Iqtidah — Daily Sunnah Tracker & Prayer Companion
The first Islamic habit tracker that unlocks 50 daily sunnahs by your prayer times.
A cross-platform mobile app that turns daily practice into something trackable. Fifty sunnahs unlock against the user's own prayer times, alongside Quran, hadith and dua, in Bengali and English. Built offline-first and ad-free so it works without a connection and without interruption.

The Challenge
The client wanted a habit‑tracking app that lets Muslims record daily sunnahs and view related Quran, hadith, and dua content in both Bengali and English. Users must see new sunnahs only after they complete the corresponding prayer, so the app has to calculate prayer times on the device and unlock content in real time. Because many users live in areas with spotty internet, the experience has to work without a network connection and must never show ads that could interrupt worship. Budget constraints limited the amount of custom backend work the team could do, so the solution had to store all reference material locally and avoid frequent server calls. The app also needed to run smoothly on low‑end Android phones and on iOS, which meant keeping the data footprint small and the UI responsive while handling time‑zone changes and daylight‑saving adjustments.
The Approach
We built the app with Flutter, giving us a single Dart codebase that compiles to native iOS and Android binaries. All static content – Quran verses, hadith collections, dua texts – was packaged as compressed JSON files in the assets folder. At first launch the app copies the files into a SQLite database, which provides fast indexed queries without pulling data from a remote API. Prayer times are calculated locally using the PrayTimes algorithm, which runs in a background isolate to keep the UI thread free. After each prayer, the repository checks the current time against the stored schedule and flips a flag in the SQLite table, making the next set of sunnahs visible. State management is handled with Riverpod, allowing the UI to react instantly to unlock events while keeping business logic testable. Localization files store all UI strings, and we switch between Bengali and English at runtime without reloading the app. This offline‑first design eliminates the need for a backend, respects the ad‑free requirement, and delivers a snappy experience even on devices with limited connectivity.

Challenges & Solutions
Challenge
Habit trackers assume a fixed daily schedule, but Islamic practice moves with prayer times that shift every day and differ by location — a 6am reminder is meaningless if Fajr is at 4:12.
Solution
Habits unlock against a computed prayer-time engine rather than clock times, so each of the 50 sunnahs becomes available in its correct window for the user’s own location and date.
Challenge
The users who most need the app are often on slow or intermittent connections, and a religious app interrupted by ads is worse than no app.
Solution
Built offline-first: Quran, hadith, dua and all tracking work with no network at all, and the product ships ad-free by design rather than as a paid tier.
Challenge
A Bengali-speaking audience is poorly served by English-only Islamic apps, but a half-translated interface reads worse than either language alone.
Solution
Full bilingual coverage across interface and content, so Bengali is a first-class language throughout rather than a partial overlay.
