Needed a cross-platform mobile app for workout tracking, meal plans, and community features — in 8 weeks.
The challenge
Shipped iOS + Android MVP in 6 weeks. Integrated Stripe subscriptions, push notifications, and a social feed.
Our approach
GreenFit's founder had a clear vision: an app that combines workout tracking, meal planning, and a social community — but they needed it fast. We chose React Native for cross-platform development, which allowed us to ship on iOS and Android from a single codebase.
Week 1 was pure scoping: user stories, screen flows, and API design. Weeks 2–4 focused on core functionality — the workout tracker, exercise library, and Stripe subscription integration. Weeks 5–6 added the social feed, push notifications, and polish.
The key technical decision was building the social feed as a separate microservice, so it could scale independently from the core app. When the app hit 10,000 users in the first month, the social feed handled the load without affecting workout tracking performance.
Timeline: 6 weeks
The results
“Six weeks from kickoff to App Store. I didn't think it was possible, but the team delivered an app that our users love — and that actually works at scale.”
