Fitness Startup Launches Mobile App MVP and Reaches 50K Users in 6 Months
About the Client
Fitness Tech Startup
London, UK
Pre-seed, 5 employees
The Challenge
Founders had strong fitness domain expertise but zero technical capability.
6-month runway meant the product had to launch fast and validate market fit quickly.
Needed a subscription billing model from day one to prove monetisation.
Our Approach
Ran a 2-week product discovery sprint to define a tight, testable MVP scope.
Chose React Native to ship iOS and Android from a single codebase.
Designed a freemium model with in-app purchase upgrades and a monthly subscription tier.
The Solution
Built iOS and Android app with workout logging, progress tracking, and social challenges.
Integrated Stripe for subscription billing and RevenueCat for in-app purchase management.
Implemented push notifications and personalised weekly check-ins to drive retention.
Results & Impact
"HashDev delivered a production-ready app in 10 weeks. We had paying subscribers before the ink was dry on our investment docs."
