Mia Health is a research-based app that tracks exercise impact to stay healthy
Some users lack strong exercise habits, and even active ones benefit from a push. Research shows they’re more motivated when sharing progress.
A complete design and flows for a "friends feature". Users can invite and add friends and share their activity.
measured in Mia’s Activity Quotient
Not a success - read reflection below.
Research and our previous app showed that users are more motivated when they can share their activity progress. This insight led us to explore different ways to make social sharing possible.

As part of our continuous interviewing efforts, we showed users sketches of the concept to gather early feedback. We learned that some users were concerned about sharing their activity during periods of illness or when they simply weren't in the mood to exercise. They expressed that constant visibility of their activity levels might feel invasive, like being "stalked" by friends.

I started a discussion about our goals for this feature to make sure we could measure its success. Our North Star Metric at Mia is the total AQ earned by monthly active users, so we aligned our objectives with it. Together with the lead designer, we set two main goals:
My colleague Valeria, the lead designer, was working on the Friends and Family subscription plan and we decided to include the AQ sharing to test it with this smaller user base. This was a perfect opportunity to release this feature to a smaller user group. This was important because from interviews we knew that AQ sharing could be a sensitive and controversial subject and needs to be approached carefully.

A Friends and Family subscription flow designed by lead designer Valeria (1st row). With this subscription the user was getting the AQ sharing (2nd row).
Based on one or two interviews where we saw a bit of a fear of sharing AQ all the time, we thought it would be best to share AQ on a limited basis so thats what we originally designed. From the interviews, we felt a bit of fear of being stalked at all time by your friends or family. So we made it possible to view the AQ of your friends only after you exercised yourself.
However, we were not 100% sure about this, so we created a way for users to leave us feedback directly in the app. And we got a lot of the same replies:
Yes! We like looking at it in my family, and it is therefore a minus that we can only see it after an activity.
We have an internal competition and would like to see aq friends at all times.
Every time a user submitted a feedback, I got an email, and at one point I got a multiple emails a week. In context that only a few hundred of users had the family subscription, this felt like a lot.
Adding friends will be a new feature and we wanted users to naturally discover this. To also motivate them to add new friends, we wanted to spark a bit of curiousity in them. With the screen here, we make them curious about how much AQ could their friends have, but also we right away show them the value of adding friends.

So after multiple iterations, we completed the designs. As of the time of writing this case study, it has been launched just 7 days ago, so we are still to see the full impact and metrics.
