Tasks My focus in this project was on the conceptual part of the interfaces, the whole user flow as well as building parts of the prototype in Principle.

What is HEJOU about?
A lot of people have mild to moderate pain in their daily life, which appear regularly. Often they don't have the time to see a doctor directly or they have to wait weeks before having an appointment. If they finally get to see a special doctor, they don't really know where the pain was, how it felt and what medication they took. 
To counteract this, we have developed Hejou. The health app HEJOU (short for healthjournal) should help the user to record pain, medication and appointments and therefore give a better overview of the health. The app is a kind of health diary that can help the doctor to interpret complaints better and diagnose illnesses earlier.
We started with thinking about what issues people have when visiting the doctor and how we could improve their daily lives. We created different features for an app and tried to organize them in different concepts with for example a tap bar for navigation. We sketched wireframes and from that possible flowcharts. 
After a discussion in the class about our navigation in the app and the logic of different features connecting to each other, we found out that the most important part is having the calendar with a clear overview. That is why we put the calendar in the focus and tried to make the part of adding entries for pain, medication and appointments as easy as possible. 
We first built the screens in sketch and animated them in principle afterwards, to get a clickable and working prototype. With that prototype we had a few user tests and improved the app after every testing session. 
It was important to us that Hejou be as clear as possible in order to be able to make quick entries in between without first having to find your way around. That's why we've chosen a simple calendar view of the week in the top bar, where colored circles around the individual data show what's available for that day's tagging. The look of the app should be factual, but sympathetic, which we achieve through illustrations, selected colors and round shapes.
Track important information:
The user can add new data by clicking the entry button and can choose between tracking pain, medication or doctors appointments. If the user chooses to track pain, there will be an illustration of a body with different marked parts which can be selected. Afterwards there are 10 questions about the symptoms and the pain. In the results, HEJOU prepares an overview of  information about where the pain could come from and what the user could try to get rid of the pain. Furthermore there is a section where the user can make notes and suggestions about the nearest doctors in the right field. If the user selects the medication entry, there is space for the sort of medication, the name, date and time when it was taken.
Monitor the health:
The main view in the app is the calendar, in which the entries are marked by colorful circles around the date. You have a weekly overview in normal view and can scroll to the left and right. In addition, there is a monthly view for an even better overview.
Find suitable specialists:
Since the results in HEJOU no diagnosis of a specialist replaced, you can arrange in the App appointments with specialists.
