Challenge
PrimeFit had a loyal gym community but zero mobile presence. Users were tracking workouts in spreadsheets.
Our approach
We mapped the key user flows, identified the minimum feature set for v1, and built with React Native for simultaneous iOS/Android launch.
Solution
A cross-platform fitness app with workout logging, AI-powered recommendations, progress photos, and social challenges. Full CI/CD pipeline with TestFlight and Google Play Internal Testing.

They built exactly what our community needed. 50k installs in 90 days without any paid UA — just great product-market fit and a flawless launch.
