The Problem

Stefan came to me with an idea for an app to track symptoms for people with various ailments and ilnesses.

He needed an app with an intuitive interface and a few features that could be activated with an in-app payment.

The Solution

I originally designed an app for fun that had a similar feature set to what Stefan needed.

We used my previous design as the starting ground for the project and built on it by adding more screens and features.
