Ngwe Khin (ငွေခင်) is a personal finance app built for Myanmar users to track everyday spending and income across multiple accounts — Cash, KBZ Pay, and other local wallets and banks. The home screen greets you with swipeable account cards and a month-by-month transaction feed, while dedicated statistics and budget pages break spending down with bar charts, net-balance trends, and per-category percentage overviews.

The app is written in Flutter with Provider state management on top of a Drift (SQLite) local database, so it works fully offline. Optional Google or Facebook sign-in via Firebase Auth backs data up to Cloud Firestore. It ships with complete English and Burmese localization, light/dark/system theming, and an in-app self-update service that checks GitHub releases for new APK versions.
