The process


We started with creating an interactive Figma clickthrough design, where we introduced the new look and feel for the app. Our goal was not just to reproduce the app in the improved UI, but to rethink its functionality, make it more intuitive and efficient. It took us one week to come up with a design concept that was accepted by the client from the first iteration. Afterward, we created screens for all app’s features ensuring design consistency. We worked in sprints, with regular demos with the client. 


The client was looking to rebuild the user interface of the app, make it modern, more appealing, and intuitive. During several discovery sessions with the project stakeholders, we determined technical and business requirements. The scope was divided into two logical parts: UI/UX design and its implementation using Flutter. 


Once we had the first designs in place, our Flutter engineer started implementing them in the app. Working independently, but in close communication with the client’s in-house backend team, we gradually delivered the new modern app.
