Works without a WitU device
Connect your Apple Watch or Garmin, or measure your heart rate with your phone camera. The better the source, the higher your Data Confidence Index (DCI).
A WitU device with dual ECG brings accuracy to a research-grade level. How it works →
Five screens that guide you step by step
Not a tracker full of numbers, but a path: measure → understand → act. Every day.
One number each morning instead of guesswork
You wake up and see a score from 0 to 100. All night, the algorithm reads your heart-rate variability, resting heart rate and sleep stages to tell you one thing: whether you have recovered or it is time to ease off.
- HRV analysis across 7 nights
- Factors in sleep and resting heart rate
- A clear recommendation for the day
Training matched to your readiness, not your calendar
Cardio, strength or a VO₂max test — the app suggests a workout type based on your morning Recovery. With GPS tracks, heart-rate zones and history, so you can see progress, not just break a sweat.
- Recommendation based on Recovery
- GPS tracks and heart-rate zones
- History and fitness trends
A research-grade reading straight from your phone
An HRV scan with a countdown and a prep checklist — no separate gadgets needed. And a 20-minute VO₂max test reveals your aerobic fitness and endurance trends.
- HRV scan with your phone camera
- VO₂max test in 20 minutes

Everyone has data. Almost no one has meaning
Most apps stop at the numbers. WitU goes all the way — to the cause, the plan and the forecast.
Collect data
Steps, heart rate, sleep, activity — all in one place.
And then go quiet. Hundreds of charts — but what to do with them is up to you.
Show stress
A stress and HRV graph throughout the day.
With no cause and no plan. You see a spike — but not what caused it.
Give a score
Recovery 62%, Readiness, Strain — one number in the morning.
Good or bad is clear. What exactly to do today is not.
Explain and predict
We layer your blood work onto your live data.
You see the cause, a ready-made plan and an early signal — before things go wrong.
We layer your blood work onto your data
On their own, the numbers are noise. Together with your biomarkers, they add up to a cause, a plan and a forecast.
Stress is not just a graph. EDA and HRV show the load, while cortisol from your blood work shows the cause. Apple Health and Whoop see only half the picture.
We spot the trend before you feel it
HRV starts to drop days before fatigue sets in. WitU notices it sooner — and your blood work makes the forecast sharp instead of vague.
- An early signal days before symptoms
- Blood work narrows the forecast from ±20 to ±3 points
- A clear plan, not just a red zone
How WitU reads your morning
Move the sliders and watch your Recovery Score and the recommendation for the day change.
With your blood work, WitU refines the result: low ferritin lowers your true readiness even after a good night's sleep.
Moderate load — a normal day.
