Interexy’s Experience In Full-Cycle Development

Crumb

Hamburg-based fintech health startup mobile application based on the idea of rewarding users for health & fitness activities

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 Store
page — 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.
