The Challenge
The client had a legacy fitness app that users abandoned within days. Onboarding was too long, data visualisations were unreadable, and the app felt slow on older devices. Reviews were harsh and retention kept sliding.
The Solution
We rebuilt the product from the ground up in React Native with a ruthless focus on performance and information hierarchy. Onboarding was cut from 12 steps to 3. Every screen was stress-tested on iPhone SE hardware. The goal-tracking dashboard was redesigned around a single, glanceable number.
The Result
Within three months the app went from being deleted in week one to being part of users' daily routines. Reviews turned warm, retention climbed steadily, and premium subscriptions became the engine of the business.
How we built it.
Two weeks of user interviews, session recordings, and App Store review mining to map every friction point in the old product.
High-fidelity prototypes tested with real users across three rounds of iteration. Every micro-interaction validated before a line of code was written.
6-week development sprint in React Native. Shared codebase for iOS and Android with platform-native feel through careful use of native modules.
Phased rollout over three weeks, with the paywall A/B-tested before full release.
