Billify is an Android app for creating invoices and tracking bills. It is written entirely in Kotlin. Users can compose invoices with line items, store them locally on the device, and review or manage them later from a single interface.
Sideload the debug APK onto a connected device or emulator:
adb install app/build/outputs/apk/debug/app-debug.apk
Alternatively, open the project in Android Studio and press Run.
Launch the app. From the home screen, tap the compose button to start a new invoice. Enter the client name, add one or more line items with a description and amount, then save. The invoice appears in the bill list on the home screen.
Tap any invoice in the list to view its details, edit it, or delete it.
