Qalb-e-Saleem — read & listen to 20 majalis on iOS & Android
We designed and built Qalb-e-Saleem — a calm app to read and listen to the 20 majalis of the Shaikh, with full audio playback, the holy shajra and biography, and offline access. Built in Flutter on a Firebase backend for iOS and Android; 4.9★ on Google Play.
The brief
A revered set of majalis that deserved a reading — and listening — experience as calm as the words themselves, on every phone.
Hizb ur Rahman Islamic Academy wanted the 20 majalis of Qalb-e-Saleem in readers' hands as a beautiful app — something to read and to listen to, working offline, on both iOS and Android, without maintaining a separate codebase per platform.
The build
We built the app in Flutter from a single codebase for iOS and Android, on a Firebase backend for content and audio. A calm reading experience plus full audio playback for every majlis, the holy shajra and biography, and offline downloads — shipped to both stores in 12 weeks.
