Increasing Adherence and Retention of an AI-Powered Health Checkup App

PreemptiveAI is a Seattle-based health tech startup focused on the growing RPM (Remote Patient Monitoring) market. With a simple daily blood pulse check up on your smartphone, PreemptiveAI is able to assess overall health, biological age, and health risks, and can communicate that risk to both the patient and their provider. In this way they are carving out a more proactive (preemptive!) approach to healthcare.

PROBLEM

How can we deliver a trustworthy, simple, and intuitive user experience for daily measurements that increases adherence to daily readings and overall app retention?

OLD DESIGN

The initial design from the CTO was largely a proof-of-concept that got the functionality there. It was also used to gain more insights into how to make the measuring experience as intuitive as possible.

Insights

From informal usability testing with many participants and discussion with internal stakeholders, the following insights became clear:

1

Onboarding needs to be more informative and educational

End users need to understand the value the app provides and why it's important to take readings everyday.

2

Reading experience needs to be more intuitive and robust

We need to use higher quality illustrations and animations to help convey how to properly take readings in the app.

It also needs to be more robust and provide more feedback to the user.

3

Patients need to view their health insights

To help motivate daily readings, patients need to periodically view their health insights and trends.

Activation + First Reading Flow

The activation flow was the most critical flow to optimize for adherence and retention. It was important to ensure the user had a positive first impression and a clear, educational, and intuitive experience from the start.

EXPLORING NEW VISUAL DESIGN DIRECTIONS

Initially I wanted to explore visual design directions that felt more warm and inviting. However, ultimately we decided to keep the visual design more neutral so that it could be white-labeled for different partners.

BRAND AND DESIGN SYSTEM

We decided to keep the brand as neutral as possible to allow for easy integration with many different partners and to keep the brand professional and polished.

WHITELABELING

The brand color token was something we could customize for different partners to match their brand colors. This allowed for seamless integration and the option of both dedicated apps and SDK with different partners.

ILLUSTRATION AND ANIMATION

I created a series of illustrations and animations to help convey how to properly take readings in the app. The audience being mostly seniors, I wanted to make the process as simple and intuitive as possible.

From an average of 40% retention after 3 months to 56% retention after 3 months.

2 new partners

The new app design helped the company find 2 new partners for remote patient partnering: Optimize Health and Evidation Health.
