Ajé

Personal finance for Cuba, as an Android app. Offline first; it talks to the banks over USSD and SMS from your own SIM. The app is a web frontend in a WebView, with a small native shell for what only Android can do.

make test   # the logic in Node, including the encoder's reference vectors
make smoke  # the frontend against a mock, in a phone-sized browser (Playwright)
make apk    # signed APK (needs keystore.properties)

To work on the frontend in a browser, serve web/ (for example python3 -m http.server -d web) and open index.html: without the native shell it runs against web/mock.js.
