Cardiac arrhythmia is a condition that causes the heart to beat irregularly. These arrhythmias can be harmless or life-threatening and affect the heart’s ability to pump blood effectively. Traditionally, cardiologists have had to rely on patients’ hearsay to understand the exact symptoms, sometimes leading to misdiagnosis. Zio was launched in 2011 to address this gap, introducing one of the first cardiovascular wearable devices on the market.

Role
The Zio app needed to cater to an older audience, so we used larger typography and clear affordances for critical interactions throughout. The core functionality had to be incredibly easy to use, considering patients might be in pain, confused, or dizzy while inputting their data.
The wearable device was attached to a patient’s chest for 14 days, collecting critical heart data that was later combined with data entered in the app after the device was returned to the care team.
The initial onboarding process was effortless, allowing patients to register in just a few taps. For return visits, patients only had to enter their 4-digit passcode.
After a patient logs in, the dashboard provides an overview of how many logs they have entered to date and how many days remain before they can remove the patch. The interaction paradigm was designed around simple taps or swipe gestures so patients could quickly enter event information.
After an event was entered, patients could pair the application with their wearable device, making the data accessible to their care team for analysis once the device had been sent in.
