Box & Found
Know what's in every box without opening it.
A home inventory people share. Photograph what goes into a box, put boxes in rooms, then find anything by search, by QR code or on a hand-drawn room map. A household can share one inventory, and members can ask each other for an item back. Box Detective lists a box's contents from a single photo.
v1.6, an installable PWA in plain JavaScript with no framework, on Supabase and Netlify Functions. Works offline, and you can start without an account and move to the cloud later.
v0.6.1, a native Kotlin and Compose port that doesn't copy the web app's weak spots: edits save only the items that changed, and deleting a household is one safe step. It has Play Billing, FCM push and a room-map editor.
In progress: a SwiftUI client, written entirely on Windows. GitHub Actions compiles it and runs it in a simulator. It reached the notifications milestone with 213 tests passing.
