Reminders — a licence renewal, insurance, a birthday. Set how many days of warning you want and it tells you every day until the date passes, even with the app closed.
Categories, search and per-category reports (from 0.5.0).
Uninstall the old copy first
This build is signed with the real release key, and the copy already on your
phone is not. Android refuses to install over a differently-signed app —
you'll see “App not installed” if you skip this.
Back up before you uninstall, or your entries go with it.
What to do
Open the Hard Budget you already have → Backup → Back up,
and save the file somewhere off the phone (Drive, Files, email to yourself).
Uninstall Hard Budget: long-press the icon → App info → Uninstall.
Tap Download for Android above. If Android asks, allow this
browser to install unknown apps.
Open the downloaded file and install it.
Open the app → Backup → Restore from backup → pick the file
from step 1.
This is the last time you'll need to uninstall. From here the app checks for
new versions on its own at startup and updates in place.
