About WitU

In just 90 minutes, you'll find out how ready you are for the day.

WitU calculates your recovery based on your device: WitU Band PRO, WitU ring, or chest heart rate monitor. It doesn't tell you how many steps you've taken, but rather whether it's worth exercising today.

What you get

A 1.5-minute morning test. Put on your device, sit quietly, and the app will measure your heart rate variability and show your recovery as a percentage. The source of each number and the date it was taken are clearly stated nearby.

ABI breathing test. Breathe calmly at a set rhythm, and the app uses the beat-to-beat intervals to calculate how responsive your heart rate is to your breathing. The first reading appears after five and a half minutes, and then updates every three. A chest heart rate monitor is required.

VO₂max test. Assesses your aerobic capacity based on your heart rate during exercise.

Sleep and activity. Sleep duration and phases, steps, and calories. If you don't have a device, the data is pulled from Apple Health.

Workouts. Cardio with heart rate zones and strength training with sets: weights are entered manually, and during a set, you can see what you did last time and when.

Today's plan. You choose what to see, plan your workouts by day of the week, and what you didn't do yesterday carries over to today.

Your goal. A big goal for the year and beyond, to which the app returns you once a week. Because the right decisions are made from a resourceful state—WitU helps you maintain it.

Support. Chat directly in the app: ask a question, and the answer will be sent there.
