To design a prototype that can mimic the future real app so design issues and user flows can be evaluated and tuned to make an app to help people navagate a test and possible illiness.
We used Adobe XD to design the prototype and used its animation features to simulate how the actual app could work and in doing so discover its touchpoints weather good or bad. We also made a web based version of the app.
Once the app was tested and approved we were asked to make the app store advertising for the product.
Here is a link to the live prototype.
