Project Idea: “I’m OK” – A Daily Check-In Safety App (Free to Build)

From r/SomebodyMakeThis · originally by u/ExpensiveDaikon6601 · August 17, 2025

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

I actually just made an app that does this! You can check it out at [checkinmore.com](http://checkinmore.com) \- would love to get some more early users. It uses Twilio for SMS, so it should work in Greece, although I haven't tested it there yet lol. And for those saying "seems pretty simple" - this was also me when I started. Turns out making an app for iOS + Android with continuous cloud monitoring for missed check-ins and SMS functionality is less simple than one may think.

Hey all, this thread really struck a chord with me. I’ve actually been working on this exact idea for a while now. I’ve designed a prototype for an app called StillHere. The idea is simple. It passively checks whether someone has used their phone that day (this would be in the form of a screen touch, unlocking the phone or something similar) and if not, it sends a gentle notification to a trusted contact. No check-in buttons, no pressure. Just a quiet, reassuring system in the background. But here’s what I keep coming back to. Why isn’t this already a thing? It feels like such a simple concept and something that could genuinely help people and reading this thread validates that. So I wanted to ask this community a few honest questions. What do you think is stopping an app like this from already existing on a bigger scale? Is it a technical issue with how iOS and Android work? I spoke with someone who said it would be extremely hard for iOS and Android to talk to each other in that way, but after more research I think a backend structure like Firebase would be the way forward? Is it a privacy concern? Or is it just that people aren’t aware of the need until something happens? Also, if this kind of app did exist, what would make it useful for you personally? Would you want notifications? Custom triggers? A daily summary? Something else? I’m thinking of launching a crowdfunding campaign soon to get the app properly developed and I would really appreciate any thoughts, feedback or even tough criticism before I move forward. If anyone wants to see the current UI mockups or designs, I’m happy to share them privately too. Thanks for reading and for the thoughtful discussion here
