Fortify is the #1 ranked pornography addiction recovery app in the App Store and Google Play, serving over 25,000 monthly active users and accumulating more than 3,000 five-star reviews. The app helps users build healthier habits through structured recovery programs, peer accountability groups, and real-time progress tracking — all inside a polished, judgment-free mobile experience. Holding the top category ranking in a sensitive and competitive space required constant attention to product quality, user trust, and app store optimization.
Technical Stack
The mobile app is built with Flutter and Dart, enabling a single codebase to deliver a native-quality experience on both iOS and Android. The backend runs on Ruby on Rails, handling user accounts, recovery program logic, push notifications, and community features. This stack gave the team fast iteration cycles — shipping new features and content updates without the overhead of maintaining two separate native codebases.
AI Coaching Features
One of the differentiating features is an AI-powered coaching layer that personalizes recovery guidance based on each user's progress patterns and self-reported check-ins. Rather than a one-size-fits-all program, the AI coach adapts the curriculum, surfaces relevant exercises, and sends timely nudges that reflect where a user actually is in their recovery — not where the program assumes they should be. This personalization significantly improved engagement and completion rates for multi-week recovery tracks.
Scale and Reliability
Sustaining 25K+ MAU at the #1 ranking demands zero-downtime deploys, responsive support, and consistent app store compliance. The infrastructure is built around reliability — background job processing for notifications, database query optimization for feed-heavy screens, and a release process that keeps the app within Apple and Google guidelines. Maintaining top-category ranking is an ongoing product discipline as much as a technical one.
