- SpO2
- Steps
- Distance
- Workouts
- Zone minutes

Baro only reads. It doesn't write anything back to Google Health.
Your data goes from Google Health to your phone. There are no Baro servers in between.
Phones and devices
Which phones and devices work.
- PhonesiPhone with iOS 18 or later. Android phones with Android 13 or later.
- DevicesAnything that syncs to Google Health. Google lists Fitbit trackers and smartwatches, Fitbit Air, Pixel Watch and Aria scales, which send weight only.
- Not supportedFitbit Ace. Google Health doesn't make data from Ace devices available to other apps.
- Older trackersSimpler devices record less. If yours doesn't record HRV or SpO2, Baro can't show it.
- You needA Google account with data in Google Health.
Scores
What the scores mean.
Each score compares you with your own recent history. Each one shows the data it used and how many nights it had. They are estimates, not a diagnosis.
- ReadinessHow recovered you are today, against your own 30-day baseline. HRV counts most, then sleep, then resting heart rate.
- SleepHours slept against the sleep you need, plus restorative sleep, efficiency, how steady your sleep times are, and overnight sleep stress.
- StrainHow hard the day was on your heart, from your heart rate through the day.
- StressHow far your heart rate sits above your resting level. Time spent moving isn't counted, because heart rate alone can't tell exercise from stress.
- Fitness AgeA cardio-fitness age from your own numbers. It isn't a biological age or a medical result.
