Common questions

The heart rate shows "--" during a workout

Zonara needs permission to record heart rate. On iPhone, open Settings › Health › Data Access & Devices › Zonara and turn on all categories. Wear the watch snugly with Wrist Detection on.

My steps or weight don't match Apple Health

Zonara reads Apple Health when the app opens and every minute while it's open. Make sure Zonara is allowed to read Steps and Body Weight in Settings › Health › Data Access & Devices › Zonara.

Blood pressure from my cuff doesn't appear

Turn on Blood Pressure for Zonara in Settings › Health › Data Access & Devices › Zonara. Some iOS versions leave it off the first permission screen.

Why is my zone marked "Estimated"?

Some inputs are missing, such as age, sex or resting heart rate. Add them in the Health app or on Zonara's Profile tab.

How do I start a workout?

Tap a goal in Zonara on Apple Watch, use Start on Apple Watch on the iPhone's Live tab, tap the complication, or say "Start Zonara" to Siri.
