Resonance is a digital health app designed to help users monitor and improve their stress resilience through heart rate data analysis and personalised breathwork exercises. The app allows users to measure their heart rate variability (HRV) using their smartphone's camera and flashlight. By taking HRV readings each morning, users can assess the resilience of their autonomic nervous system without requiring any extra devices.
My product design process is oriented around the Double Diamond approach, which emphasises a thorough understanding of the problem space before exploring different design solutions.
One of the biggest challenges for a B2C product is retaining new users. After shipping the first MVP, we observed a significant drop-off after the first day. Looking at the product analytics revealed that users who returned the next day were much more likely to continue using the product.
The main objective is to increase the number of users who return to the app on the day after their initial installation.
Diving a bit deeper into the product analytics showed that most users already dropped of before taking their first HRV reading.
We conducted user interviews and observed users using the product to get a better understanding of:
After analyzing all user interviews and observing users in real-time, we have identified the following common themes:
How might we help users to take their first two HRV readings, while also helping them understand the results and educating them about the value of daily HRV readings?
Exploring different solutions through a combination of brainstorming sessions and iterative sketching.
Prioritising different solution ideas on estimated effort and impact with the whole team including engineers.
The experiment showed that the new version improved the user retention significantly.
