Bitcoin to Fiat Android App

Client & Industry

Coinfetti is the first mobile app that converts Bitcoins to fiat on your prepaid debit card (Paypal, Payza, Paxum, Skrill) INSTANTLY with no registration required conserving the Bitcoin spirit.

My Role

I designed the Android based version of the MVP (Minimum Viable Product) for the Coinfetti startup as a freelance project. Based on the initial version of the app and interviews with the stakeholders I adjusted the information architecture, optimized the user flow and ultimately the experience of the user.


User Experience
User Interface


  • lack of clarity regarding the sort of service the app would provide
  • initial fields setup, while brief, didn’t leave room for notifications
  • feedback from the app was minimal
  • there were two simultaneous overlapping flows
  • support for more than one type of card was not marked
