My first step was to learn all about blood pressure from sources like the American Heart Association (AHA), Mayo Clinic, Harvard health and others.

Once I gathered enough knowledge to understand how blood pressure worked I turned to competitive analysis to see how other apps tracked and displayed the information.

Garmin has charts and graphs to display many kinds of data but none of the charts we had would be very helpful to display the data we wanted to show.

To show ranges and multiple readings in a single day weren't very difficult but to show that data over time was a little more tricky.

For the today view, I utilized a chart similar to what the AHA used to show the ranges of Normal, Elevated, Stage 1, Stage 2 and Hypertensive crisis in some cases. A dot would represent on an X and Y axis chart to show that day's readings.

For past data we would display a line to show the systolic and diastolic ranges of readings. Along with list cards that could take you to a more detailed view of your data.

We tested designs with different demographics that were familiar with Garmin's ecosystem, as an upsell item for existing customers. We also tested designs with customers that weren't familiar with Garmin Connect to make sure the designs were understandable to new users, we wanted to validate that the range charts were effective at conveying the information.

Being able to share your readings with your doctor was another key feature within the blood pressure feature. You could download your reports and print them or email them to your health care provider.

I worked closely with devs to create, implement and test the new charts and graphs. When the project was completed we took the exportable reports to other health metrics like Weight, Hydration, Pulse ox, Advanced Sleep, Menstrual cycle and pregnancy, HRV and ECG Readings.

I worked with writers to ensure there was robust help content offering users clear, actionable insights to support more informed and health-conscious decisions about their well-being.
