As an app the was designed to collect and store medical records, Prime provided interesting user experience design challenges. The most important of these challenges was the process users took to sign up for their account.

Though the off-white background created a nice sense of warmth, the first version of Prime featured a very simple landing view that asked users to sign create an account without providing much context or promising value.

I greatly prefer apps that let me use them without creating an account, but for Prime user accounts were a necessary method to protect users’ privacy and keep records secure.

To improve the experience of signing up for Prime I started by adding an informative scroll view, as well as the choice to sign up with an email account. The majority of users continued to prefer the convenience of Facebook-based authentication, but providing additional methods of signup helped them trust the app.

I interviewed users to determine the right level of conversational voice—formal enough to be trustworthy without being overly clinical or cold.

The final step of the sign up process was the step asking users to log in to their hospital account. After many iterations I settled on a simple button that would kick off an email support flow. For the most part users didn't need much help finding their password, but they were installing Prime when away from their computer—by emailing them with setup instructions I was able to remind them to add their password at a time it was convenient.

Users loved collecting their medical records in a simplified timeline of health events.

They also loved the discrete notifications that alerted them when new health information was available from their healthcare provider.
