Polar with Health Connect and BIOXS: data and limits

What Polar Flow shares with Health Connect, how it reaches BIOXS and which limitations to check.

BIOXS does not connect directly to the device. The documented route is Polar → Polar Flow → Health Connect → BIOXS. Results depend on model, version, permissions and the categories written by the app.

Documented app data

Active and total calories; distance, sessions, laps and routes where available; workout heart rate, speed, daily steps, sleep and stages; SpO₂, height, weight, resting heart rate and VO₂ max.

How to connect it

  1. First sync the wearable with its official companion app.
  2. Enable Health Connect from the source app settings.
  3. Grant only the write and read permissions you intend to use.
  4. Check one identifiable record in the app, Health Connect and BIOXS.

What to check

  • Device model and app version
  • Exact data category
  • Date, time and unit
  • Read and write permissions

Compatibility limits

Flow shares new data after connecting. Weight, height, resting heart rate and VO₂ max are described as physical settings, not necessarily continuous measurements. Not every Polar sensor or watch supplies every metric.

A compatible brand does not imply that every model or proprietary score is exported.
