• Measure and improve your VO2 max with accuracy far superior to current smartwatches and close to that of a calibrated lab test.

• Import workouts from Apple Health, Fitbit, Polar, and Garmin.

You can turn off auto-renew at any time from your app store account settings. Cancellation of the current active subscription period is not allowed. If you are eligible for a free trial period, payment will be charged to your app store account as soon as it has expired. If not, then it will be charged at confirmation of purchase.

Patients with cardiovascular disease should consult a physician before engaging in high intensity interval training.
The app uses your phone's GPS to track your position during use. Continued usage of GPS running in the background can dramatically decrease battery life.
