It’s a habit tracker app with fairly simple features, built with Flutter. Syncing to Google Drive incrementally using timestamp last synced data and offline-first mode, currently only targeting Android. It uses Google Drive application-spesific data so the app can only access this app directory only and can’t access your other data.
