We identified three key users and looked at the overall user journey to understand offline flows and how the different users interacted. The experience of getting a medical record attested is a largely offline experience, therefore it was a primary consideration when designing this app.
We focused on building an initial proof-of-concept (POC). This was quickly designed and developed, and in matter of weeks we had real users using it via Testflight and providing valuable feedback for us to improve the product.
An improved experience was designed incorporating user feedback and additional functionality to cater for different use cases while maintaining a simple overall experience for the user. This was a continuos and iterative process.
