Alberich

For Android. Your pouches are kept on your phone and nowhere else, and it works with no internet. Open the downloaded file and let Android install it (it will ask permission for your browser the first time, because the app is not on a store). Then add the widget: press and hold an empty spot on your home screen, choose Widgets, find Alberich, and drag it out. Reminders come from the app itself, so allow notifications when it asks.

Optional. It reads your bank and card statements and works out your spending credits from them, files receipts, and keeps a copy of your phone's pouches. It needs Python 3.10 or newer. Unzip the folder, run python3 start.py (on Windows py start.py), and your browser opens; choose a passphrase. To connect your phone, open the Phone page, make a pairing code and scan it with your phone's camera. They talk over your home Wi-Fi; nothing goes through the internet. If you use Tailscale, the pairing code includes your Tailscale address too. Reading photographed receipts needs the Tesseract program, and the assistant needs your own Anthropic key; both are switched off otherwise.

The same app, running in this browser tab. The demo is filled with made-up pouches so you can look around. The other one starts empty and keeps your pouches in this browser only, which works on an iPhone too. Outside the Android app there are no reminders and no widget.
