Challenge
Ladder is a subscription strength app built around goal-oriented programs from elite coaches and a supportive team community. The main delivery challenge was to give users sensitive health information presented calmly, clearly, and without adding cognitive load, while keeping Match, Program, and Coach consistent across the complete journey. We framed the engagement around the smallest production-worthy flow first, then expanded the scope without weakening the underlying component and data model.
02
How we built it
We started with the navigation model, reusable screen primitives, and the data contracts behind the most important user journey. From there we delivered Match, Program, and Coach in vertical slices, so every milestone included a usable interface, live data, validation, and error handling. Realtime updates and offline recovery were designed together because mobile connectivity could not be assumed. The application foundation centred on React Native, Expo SDK 54, Expo Router, and TypeScript, followed by device testing and release hardening for iOS and Android.
03
Delivery
The delivered scope brought Match, Program, Coach, and Progress into one coherent cross-platform mobile release. Live updates, recovery states, and operational feedback are part of the core flow rather than late-stage patches. For Ladder, the practical result is a product that communicates its value quickly while giving the team a maintainable base for continued delivery in health & wellness.
