Interval Timer: HIIT Coach

HIIT Coach is an interval timer that lets you keep track of your cardio fitness (VO₂ max) improvement.

To get your heart rate in the app, you can use Apple Watch or heart rate monitors with Bluetooth. Garmin watches with Virtual Run are supported.

Cardio fitness is measured with a modified Bruce protocol test you can perform on most treadmills. The test consists of stages with increasing intensity and ends when you reach 85% of maximum heart rate.

HIIT Coach makes HIIT workouts more fun by telling you when the target zone changes, so that you're free to focus on your music and your running form.

You can do HIIT workouts on Apple Watch, so you don't have to bring your phone.

HIIT Coach comes with a collection of default workouts, but you can also create custom workouts. Whether you're aiming for speed, endurance or weight loss, you can choose or create an appropriate workout in the app.

Your past workouts are saved to your workout history, where you can see the heart rate graph and and calories burned.

Your data is stored in iCloud, which makes it accessible across your Apple devices.

Always consult with a healthcare provider before starting any new exercise program. Exercise can carry risks, especially for people who have certain medical conditions or who have not been physically active in a long time. It's important to understand that using this app does not replace a doctor's advice or treatment.
