Mobile / Local data
Broom
An Android household-task app with data on the phone and sync over the same Wi-Fi network.

The problem
Bring household tasks to the phone without requiring a running server or an account.
My contribution
I rebuilt HomeSync as an Android app with React, Capacitor and AI assistance. QR pairing enables automatic sync between phones on the same Wi-Fi network.
Available evidence
The public repository contains the code and an APK in its releases.
Usage and limits
The documented sync is local: it requires QR pairing and phones on the same Wi-Fi network. It is not a cloud sync service.
