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!
