Fitness Tracker Mobile App

Cross-platform fitness app with workout plans, nutrition logging, and progress analytics.

The challenge

The startup needed a polished MVP to validate subscriptions but had no unified experience across iOS and Android. Retention dropped after week two due to cluttered onboarding.

Our solution

We built a Flutter app with guided onboarding, personalised workout plans, Apple Health / Google Fit sync, and streak-based engagement. A lightweight admin panel tracks cohort retention.

Measurable results

50K+ Monthly active users
+55% Day-30 retention
4.7★ App store rating

Client feedback

“They understood our fitness audience and shipped an app we were proud to promote on day one. User feedback has been overwhelmingly positive.”
