Amazon’s first health & wellness application, Halo.
Amazon Halo, at the core, was a service that encompassed everything health and wellness. It offered wearables you could connect to the Halo app for a central location to track fitness, sleep, mindfulness, nutrition, body fat, and so much more. This project highlights the addition of what we called "Insights"—a feature in the app that gave in-depth recaps of your week.

The problem
Giving customers a weekly recap of their health and wellness was more than just splashing on an infographic and calling it a day. We had two types of customers: folks who wanted their information bite sized, and folks who REALLY wanted to dig into their data. To top it off, we weren't just tackling fitness. This small feature was quickly becoming a huge portion of the app experience on its own.
Solving for information overload
With how much data we needed to cover for each pillar of health, tabbing was the way to go. Users could easily toggle in between each category they wanted to see recaps of, and dive deeper into the details on each page.

To solve for our heavy and light users, I designed each insight card to showcase high level data with drop downs to learn more.

User testing results
We ran tons of tests. Most of them revolved around which visualizations read the quickest and easiest. Solving for our light users was much tougher than solving for the heavy—they wanted complicated information digestible within seconds, or they'd lose interest. However, it was important we accommodated both.

After multiple iterations, results from our studies showed light users were pleased with the snackable content. They appreciated the quick reads simple graphics provided for each card, and mentioned the lack of interest they had in the content tucked away—noting it was nice they could just make it disappear off their main page.

Heavy users really enjoyed charts and graphs they could read into. They cared a lot about the numbers and reacted positively when discovering they could reveal more information within a card.

Greatest challenge
New features, old UI, and a work in progress brand book. We were moving FAST. On top of the challenges within the project itself, I was solving for a middle ground between our old UI and a new brand vision I had been developing over in the branding world.
