What it does
- Step and distance tracking from the phone's hardware step sensor, working offline.
- Phone lock: optionally locks the phone until a daily step target is reached, with an allowlist for essential apps.
- The "System": daily quests, experience points, ranks from E to S, and a seven-tier streak flame.
- Daily walk challenge: suggests a nearby place to walk, at the best time for the weather and prayer times (Saudi cities), using OpenStreetMap and Open-Meteo.
- Walk maps of every session and the streets you have explored, plus a six-month bodyweight training program (Arabic and English).
- Optional account with private cloud backup and groups with leaderboards.
How it is built
- Kotlin + Jetpack Compose, Room, and WorkManager, with the core logic in a pure-Kotlin module tested without the Android SDK.
- Firebase (Auth, Firestore with tested security rules, App Check) for the optional account and groups.
- CI/CD: GitHub Actions runs unit and emulator tests and publishes signed releases.
- Fully bilingual, right-to-left first.
