Challenge
Creation of the first MVP for the company from scratch based on a project that was created in a very short time to convince investors of the need for a financial round.
Solution
We decided to rewrite the whole product from scratch, using native iOS development technologies.HealthKit integration was one of the main reasons for us to make this kind of decision since the app was built using cross-platform React Native technology.
Result
We got to the top 17th of the German Health & Fitness App Storepage — the product was competing with a multi-million dollar application, and we built an MVP within 1.5 months with under a $20k budget. Awesome user reviews are the best validation of the work done.
