A way to see what’s draining your brain (not just your to-do list)
I’ve been thinking about this for a while and I’m surprised it doesn’t exist in a clean way yet. Most productivity tools track tasks. This would track mental load. The idea: You dump everything that’s in your head (tasks, worries, decisions, unfinished thoughts) and instead of a list, it turns into a visual “cognitive load map.” Not just what you need to do, but: \- what’s taking up the most cognitive weight \- what’s stuck / unclear \- what’s draining vs lightweight \- where your attention is fragmented So instead of asking: “what should I do next?” It answers: “what is actually weighing on me right now?” I think the unlock is making something invisible (mental load) visible in a way that’s instantly understandable. This feels especially relevant for: \- people juggling a lot (work + life) \- founders \- neurodivergent brains \- anyone who feels constantly “full” but can’t pinpoint why The MVP could be super simple: \- brain dump input \- basic categorisation/clustering \- visual map (even just nodes or weight sizing) Not trying to overcomplicate it, just enough to see if that moment of clarity hits. Curious if anyone would actually build something like this or if you’ve seen anything close?
A digital space that only exists at night
There’s an entire world of people who are awake at night: parents, shift workers, insomniacs, people going through something. Right now they’re scattered across Reddit, TikTok, random forums. Idea: a platform that only opens at night. – opens around 10pm (local time, wherever you are) – live chat rooms + quiet spaces – low-stimulation, calm design – optional anonymity And then at sunrise, everything disappears. Conversations aren’t saved. Nothing to scroll back on. Just a shared moment with whoever else was awake. Less social media, more “you’re not the only one here”. Feels like something that should already exist. Like a temporary internet that only exists for people who can’t sleep.
A way to leave letters, voice or video recordings for my descendants, a way to live on long after i'm gone
I never met my grandparents. I have photos but nothing that tells me who they actually were. What they dreamed about. What they were afraid of. What their voice sounded like. They lived whole lives. They had fears, loves, dreams. And all of that is just gone. Not lost in tragedy. Just not passed down. I've been thinking: what if I could leave something for my grandchildren or great-grandchildren? Not just photos in a box. A letter. My voice. The messy, real parts of who I am. Something that gets delivered 50 years from now, when they're old enough to want to know who I actually was. I'm not technical. I don't know how to build this. But I'm wondering * Would anyone else use this? * How would you even make sure it lasts that long? * Would it matter to you if your grandparents had left something like this? Genuinely curious if this is just me or if others feel the same.
A "dating" app where you can post an event you are going to, and find a date to go with you.
UPDATE: I made it! [https://plusonematch.com/](https://plusonematch.com/) Basically, you just input your personal stats, and the stats of who you are looking for. Then you input stats about your event, or about the event you want to go to. You can do either, or both. And you can input more than one event. You input the date of the event, or the dates you are available to go to events. If you are looking for an event to go to, then the app shows you a calendar, with your matches. You send a match a like, and if they like you back, then you can start chatting. The "events" can be weddings, concerts, work galas, parties, or even just dinners. It's a bit like Meetup. Except it is for one on one dates, not a group. And it doesn't have to be just dating. It can also be if you want someone to go with you just as a friend.
911 Should Have FaceTime
Seems more than logical to add FaceTime features to Emergency Service Calls. Obviously the caller wouldn’t be able to see the operator but the they’d be able to show their situation and it would cut down on a number of different issues in my opinion. Police body cam footage, unfiltered online videos and CCTV cameras already show violent, wild and disturbing videos so giving the argument that someone (especially law enforcement) doesn’t want or need to see it is just silly. If you’re an operator for 911 and can’t do your job correctly without getting worried or shaken-up then that seems like a pretty clear sign that you should probably seek other employment because first responders jobs aren’t easy and any assistance before getting to a scene is usually more than appreciated.
A dead-simple “Renter’s Digital Vault” app for timestamped move-in/out proof to win deposit disputes
Somebody Make This: Renting in the US is a nightmare when it comes to security deposits. Landlords withhold money for “damage” that was pre-existing, or tenants can’t prove they requested repairs. The standard advice is take dated photos/videos on move-in day, email them to yourself/landlord, save receipts… but it’s messy photos get lost in camera rolls, hard to organize “before vs after,” and no easy way to compile everything into a dispute-ready report. Idea: A lightweight mobile app that’s literally a digital vault just for renters: • Guided move-in/move-out checklists (room-by-room prompts for photos, notes on existing issues like scratches/stains) • Auto-timestamp, geotag, and hash photos/videos in-app for tamper-proof proof • Quick uploads: rent payment screenshots/receipts, repair request emails/texts, appliance warranties • Search/filter by address, date, category • One-tap export: Generate a clean, timestamped PDF “Evidence Package” you can send to landlord/small claims court • Bonus: Gentle nudges/streaks/badges to encourage consistent documentation (e.g., “Upload rent proof this month? + streak!”) Nothing fancy no AI overkill, no social features. Just reliable, tenant-focused storage that’s easier than scattered Google Drive folders or Notes app. I’ve checked a bit there are general doc scanners or landlord tools (like Avail, RentRedi), but nothing super tenant-centric and effortless for this exact pain point. Existing workarounds suck when you’re in a dispute 10-12 months later. Questions to gauge if this is worth building: 1. Renters: Would you actually download/use this? What’s your current system (and how often does it fail you)? 2. What killer feature would make it a must-have for you? 3. Devs/makers: Does this sound buildable as a simple MVP (maybe Flutter/React Native + cloud storage)? Any obvious existing apps I’m missing? 4. Any red flags (privacy concerns, legal issues with timestamps, etc.)? Just testing the waters curious if this solves a widespread problem or if it’s niche. If there’s demand, maybe it inspires someone (or me) to prototype it. Thoughts? Thanks in advance!
A stationary bike I can ride at night to charge up my e-bike so I can ride to work in the morning and not arrive to work sweaty, but still know I put in the effort.
possible? practical?
APP IDEA: Pinterest/Pinterest board for memes
Right now, most memes I like end up as: • screenshots • Instagram saves • WhatsApp forwards • or lost forever There’s no good way to organize humor by context — like mood, phase of life, work culture, or internet moments. The idea: • A Pinterest-style app, but only for memes • You create boards (public or private) • Boards are the main thing people follow, not profiles • Some boards could be curated by well-known internet tastemakers and updated regularly (possibly paid, possibly not) Not a social feed. Not chasing virality. More like collecting and organizing humor the way Pinterest organizes ideas. Genuine questions I’d love honest answers to: 1. Do you already “collect” memes in some way? 2. Would you ever follow someone’s meme board because their taste matches yours? 3. What would make this unnecessary when Instagram/Reddit already exist? 4. Would you pay a small amount for a consistently good, updated meme board — or is that absurd? Tear it apart. I’m more interested in why this fails than why it succeeds.
A service where you pay someone to waste a scammers' time for you.
I have been getting spammed constantly by scammers. It's so tiring. I watch a lot of youtube videos, where people waste scammers' time. And so many of the comments say that we should do things like fund government call centers, to do what the youtubers are doing. It gave me an idea; what if there was a service where you pay someone to waste a scammers' time for you. Basically, you receive a text or email from the scammer, and you forward their contact info to the time waster. They waste the scammers time, and record a video of it, to send to you for proof. I feel like the more time these scammers are tied up talking to someone who is wasting their time, the less time they are going to spend scamming vulnerable people. And I've also heard that after you mess with a scammer, they tend to leave you alone for a bit. I'm not entirely sure about the legality of doing something like this. It was just a random idea I had. I would appreciate advice.
APP IDEA: LinkedIn But For Landlords and Tenants Where They Can discover Uber Style and match Hinge style
Most rental marketplaces only let **one side** judge the other. Tenants are screened. Landlords are not. Or reviews exist, but they are fragmented, unverifiable, or anonymous to the point of being useless. This platform is built around **mutual accountability**. Both landlords and tenants can: * Build a reputation over time * Leave structured, verifiable feedback after a tenancy ends * See historical behavior patterns, not one-off complaints The goal is not to “name and shame,” but to **reduce asymmetric risk** before a lease is signed. Think of it as: * Airbnb-style trust signals, but for long-term rentals * Less hearsay, more documented experience * Fewer surprises after keys are handed over I am here to stress-test the idea: * Would you actually use something like this? * What would make you trust the ratings? * What would break it immediately? Not selling anything. Looking for honest feedback, edge cases, and reasons this might fail.
A photo app that allows you to take pictures while displaying a translucent overlay of another photo.
This would be extremely useful for comparison shots, stop motion, etc. Want to take the same family photo every year? Just overlay last year's photo to get everyone positioned right. Taking pictures of real life locations from a movie? Overlay a still from the movie so your picture can match it. You could toggle the overlay on and off, and even if it was turned on it won't show up in the new photo, but it would be very helpful in a number of situations to be able to do that. This idea is so simple that I feel like it probably exists already but I've never seen it. If it does exist, what is the best app that can do this?
Free non-profit dating site
I see there are a lot of problems when it comes to dating sites or apps. Why can't someone just build one that unites all the good things like: \- its free but u can donate \- there's no swiping, just profiles with people near your location, no algorithm \- you have to have a profile text wich people have to read before they can send you a text (or sth similar, i don't have a plan on how to do that yet) \- avoiding that some users drown in messages (still no solution, just the goal) \- no scammers or inappropriate behaviour, maybe use votekick? I'm from Germany and mostly on kinky apps like Fet (not Fetlife) and Joyce, also Tinder. I'm doing quite OK, but **ONLY** if i have the "premium" version, what enables sending messages, wich should always be a basic feature in my opinion.
A website where people can give strangers birthday gifts.
UPDATE: I made this! Here is a link to it. I would appreciate any feedback: [https://kindredbirthdays.com/](https://kindredbirthdays.com/) I recently saw a video of a special needs man that called the police to wish him a happy birthday. It made me really sad. So I had the idea to create a website where people (like artists, poets, bakers, etc) submit some of their work for other people to receive on their birthday. They select the maximum amount of people that can receive it. I think the website should allow a maximum of 50 items. People who want to receive "gifts" can sign up to the website, input their birthday, and fill out a survey to see what gifts would be the best for them. They can change up the survey as much as they want, up until the day of their actual birthday (when they receive their gifts). And on their birthday, they are matched with 5 gifts. I think this would be a good way to make some people (like that special needs man) feel more appreciated on their birthday. And creators can use the website to get some of their work out there, and reach more people. I feel like it would be easy for people to abuse a website like this. But idk, it's just an idea I have. I would appreciate feedback.
Why don’t we have a reverse Marketplace app?
What if instead of sellers listing items, buyers listed what they want? Sellers could scroll through requests, match what they already have, and send an offer. Way less scrolling, way faster matches, and people get money for stuff they forgot they owned. Basically a demand-first Marketplace. Would you use this?
App idea: An ADHD app that lets you brain dump all your thoughts to automatically organize them
Hi everyone, I had this thought about building an app where users could just dump everything they have in mind into the app. So they just start the app, click on the microphone, and then they just talk. Everything that is on their mind, they can just dump into the app (e.g., if they have ideas of things they need to do or if they have something they worry about). After they're finished, the app shows actionable advice. For example, "Okay, so you had this app idea. What is it about? Should I create a new note that explains this idea?" and then you can accept it. It might also say, "Hey, you talked about that you want to call your parents. Should I create a reminder for that?" And you click yes please, and it automatically creates a reminder. All in all, the app just helps you clear your thoughts and actually do something. So when you're like overwhelmed, you can just talk and it perfectly helps you. What do you think about such an app? Would you use it? What else would you need to have in this app? I'd love your feedback on this idea!
Tinder but for Music
Hi all, Thoughts on this app idea which essentially is Tinder but for Music? Swiping right will add the song to a playlist you choose, swiping left will adjust your recommendations. Any feedback is appreciated.
An app for watches that will wake you up during nightmares
I live with complex PTSD, and one of the most difficult parts of it is the night terrors. I don’t just wake up startled my heart is pounding, my body is shaking, and it feels like I’ve been running for my life in a place I can’t fully remember. Sometimes I lie there frozen, trying to calm my breathing and remind myself that I’m safe, but my brain hasn’t quite caught up. It would mean so much if there were something that could pull me out sooner, anchor me back to the present, and help my body and mind remember that the danger is over
A minimalist net worth app for people who only update their finances once or twice a month
I use my budgeting app to log invoices once a month, bills once a month, and check how my net worth is doing. That’s it. I don’t track daily expenses — I just go in once or twice a month to update everything. The problem? It’s still too much work. Every month I open my app, and there’s a mountain of piled-up transactions. It’s tedious, stressful, and never perfectly accurate anyway. I just want something simple that lets me: * Log only big stuff (bills, debts, paydays) * Manually enter balances for savings, cash, and debt (no bank linking) * Get bill reminders so I don’t forget * And see a net worth graph that tracks my progress over time Basically, an app that focuses on monthly check-ins, not daily logging. Does anything like this exist? Or should I go build it?

Ever finish a non-fiction book and immediately forget everything? Here’s an idea to fix that
We’ve all been there: you read a fascinating non-fiction book, underline passages, maybe even take some notes… and a week later, it’s all gone. Nothing sticks. I’ve been thinking about how we could actually *remember* what we read without turning it into a chore. Here’s a concept: Imagine an app that lets you capture your thoughts and highlights **while you read**. Not just quotes, but questions, insights, and ideas that pop up. You just speak while you read and the App would sort the input. Then, it turns them into bite-sized “learning exercises”: * Quick quizzes or fill-in-the-blank prompts based on your own notes (like a personal Duolingo for books) * Rewards or progress tracking when you revisit ideas and spot connections * A way to organize and cross-link your notes so you can see patterns and relationships across chapters or even different books Basically, it’s like turning your reading into an interactive, playful learning experience. You’re not just consuming content—you’re building a knowledge map as you go. Curious: would you actually use something like this, or does it sound too “nerdy”?
Move your car please.
Someone needs to create a like QR code sticker that people can put on their car windows so other people can contact them instead of just putting your phone number in the window or having people call 311. How it works: Person who is trying to contact driver scans QR code, it opens a trustworthy app or website. The person chooses an option about what message gets delivered to driver. To prevent harassment or inappropriate conversations, there’s no custom options. So like options can be: - [ ] You have me blocked in. - [ ] Your car alarm is going off. Your name and number is not disclosed to the person sending the message. The person receiving the message will also not know the name or number of the person sending the message. People can also choose timeframes they would like to have the QR active so people don’t play pranks. Like if you’re moving and you’re double parked and going in and out, you can set an active period to be from 1pm-2pm. You can do the same during alternate side parking time. I think this will be popular in big cities where parking is always an issue. Also maybe there can be a way for law enforcement or the fire department to bypass the active period in case of emergencies like needing to access the fire hydrant or something else.
Why can't Reddit detect content that you've already seen so you don't see the same thing across multiple subreddits? (Or reposts in a certain amount of time)
I probably shouldn't have subscribed to so many similar subreddits but it seems like it would be fairly simple to program Reddit to avoid repeating content. Why isn't that an option? Is there a better Reddit app that does this?
Book-scanning app
I would love an app that scans book spines in bookshelves at the book store, and checks if any books appear in my to-read lists on my reading apps. I frequent second-hand book shops with wide assortments of books, but there is no way I can keep my long to-read list in my head to be able to snap up a bargain. I know Good Reads scans front covers but if you scan the spines you can do an efficient search of the book shop.
Project Idea: “I’m OK” – A Daily Check-In Safety App (Free to Build)
Hi all, I’m sharing an idea that I hope someone out there will find meaningful enough to build. I’m not hiring, I’m not seeking royalties, and I’m not asking for credit. I just want this app to exist—for myself and for others who live alone and want a simple way to stay safe. **🧩 The Concept** A minimalist Android app that asks the user to check in once a day—just press a button or respond to a prompt. If the user doesn’t check in within a set time window (e.g., 24 hours), the app automatically alerts a nominated contact via SMS or email. Think of it like an Excel =IF() function: =IF(UserCheckedInToday, "All Good", "Send Alert to Emergency Contact") **🎯 Key Features** * Daily check-in prompt (notification or widget) * If no check-in within X hours, send alert to contact * Alert includes timestamp, last known location, and optional medical info * Works offline (SMS-based alerts) * Customizable check-in frequency and alert delay * No panic button—absence of check-in is the trigger **🧠 Optional Enhancements** * Smartwatch integration (tap “I’m OK” from wrist) * Failsafe triggers (e.g., no phone unlock for 24h) * Local language support (Greek + English) * Multiple emergency contacts **👤 Target Users** * Elderly individuals living alone * People with chronic health conditions * Remote workers or expats * Anyone who wants peace of mind without intrusive tech **📜 Sample Alert Message** “Stelios hasn’t checked in today. Please check on him at \[address\]. If no response, call 166 (ambulance) or 100 (police). Last known location: \[GPS link\].” **💬 Final Note** I live in Greece, in Kalamata, and I’ve searched the Play Store and asked other AIs for help. Most apps either don’t work in my region, rely on manual panic buttons, or send validation links that fail. I’m offering this idea freely to anyone who wants to build it. If you do, I’d be thrilled to see it come to life. Thanks for reading, Stelios
A Fake/AI tag for every post that's faked or made with AI on Reddit where a seperate comment thread can dispute the truth behind it
Reddit needs to make improvements or it's going to fall behind. One thing that drives me nuts is almost every thread, people are arguing over if it's fake/AI or not. I'm thinking that there needs to be a community ability where anyone can tag it with "faked by AI" "Skit", "missing context", etc. and if it's agreed with by enough people, it appears for everyone. It detects common sentences put in the regular comments and before they enter it, it directs them to a special comment section where people can discuss if it's real. You can see the most common arguments on both sides of the screen, add any new ones and you can vote if you think it's real or not. Another idea off the back of that one is having AI let people know if someone has already said the same thing in the comments. At least, have the reader on the other side ask to not see the exact same comment twice, maybe send a notification to the person that made it, just letting them know that their comment will be minimized because it's been said at the same time.
Drive the tollway, opt in to the lottery
If you drive on a toll road, be given option to add a nominal amount to the toll (like $0.10-$0.15) to become eligible for a weekly drawing. Each “opt-in” to pay extra earns you an additional entry. Drawing every Sunday. Winner gets 80% of the total amount. Requires new legislation and partnership with the state lottery system, but the infrastructure for the toll roads should already be in place. Thoughts?
A platform similar to Tinder, except for people to trade things.
I am thinking of making a website where people can post an item that they want to trade. They input the items title, pics, description, and categories. Then they input the categories they want to trade it for. They see the items that match with theirs, and they can like, or reject their matches. If two items like each other, then a chat is formed, and they can talk about trading.
An AI to flag any video using full or partial AI
AI video generation is getting more and more realistic. You might think "I'm so smart, I will never fall for AI generated content". The truth is that your parents are already believing what they see in their facebook made with AI. We are very close to not be able to tell if a video is real or AI made. So I think it would be cool if there was a **service**, a **chrome extension or an app** that could easily identify if a video was made with AI.
An app idea to organize your space
Would people be using an app where they can click a picture of their room, office, garden, desk, wardrobe or any other unorganised space and the app give steps to organize this space. The idea is to remove the cognitive load and the friction to start.
Collaborative Music Queue
I'm looking for a simple web app that lets me host a collaborative music queue. - The host opens a web page and connects to a speaker or just uses their phone. - Other people can join via a link or QR code and add songs to the queue. - Music should play on the host’s device. - No Spotify API! Ideally, use YouTube or similar public sources. - Bonus points if there’s basic voting or song skipping. Would love a clean interface. Something like a party jukebox for the web. If anyone builds this, I’d definitely use it at events.
YouTube should provide an opposite to the subscribe button
Sometimes a video is so trash you want to ban the entire channel from your recommendations. "Don't recomend channel" option is only available on the YouTube web home screen. However, this is extremely limited. There is no simple "Don't recomend channel" on the channel page, or anywhere on YouTube for Roku. On the web, the option isn't somewhere you can get to, because home page loads whatever recommendations rather than some channel that you specify.
A website where you can find all farmer's markets in your location.
I'm thinking of making a website where you can input your location, and see all the farmer's markets around you. You can filter the markets by specific days of the week, times, and distance from you. Basically, the organization who runs the farmers market gets on the website, and submits their market's name, description, location, and hours. When the farmer's market is on the website, the vendors for the market submit their store's name, description, and booth number. The market has to approve them. Vendors will have their own profiles (under the market's profile) where they can post their personal website, contact info, and the items they sell at the market. Visitors to the website can leave reviews on both the farmers market, and the individual vendors. I feel like this will help make it easier to find local farmer's markets. And easier for farmer's markets vendors to sell their products (because they will have somewhere that people can easily find their website).
