Sync any fitness tracker with Apple Health

Almost every fitness tracker can get its data into Apple Health on iPhone: Garmin, WHOOP, Oura Ring, Polar, COROS, Fitbit / Pixel Watch, Amazfit, Xiaomi, Withings, Ultrahuman Ring, Wahoo, Strava, Peloton and MyFitnessPal write to it natively through their own apps; Suunto, Huawei and Zwift write some data types; Samsung Galaxy Watch needs a third-party bridge app.

What arrives differs by device, so each guide below lists exactly what syncs, the current menu path and how to keep Apple Health from counting the same steps twice.

How Apple Health merges data from several devices

Apple Health keeps every sample with its source. When two devices record the same data type, the source at the top of that type’s Data Sources & Access list wins, so steps and energy aren’t added up twice.

  • Default order: data you enter yourself comes first, then iPhone, iPad and Apple Watch, then apps and Bluetooth devices. A newly added app or device goes to the top automatically.
  • Choose the winner per data type: the order is set separately for steps, energy, distance, heart rate and so on, so you can trust your tracker for sleep and your iPhone for steps.
  • Workouts are listed per source: if two apps both write the same session, Health can show it twice. Switch off Workouts sharing in one of them.
  • Activity rings need Apple Watch: data from other devices appears in Health but doesn’t move the rings.

Apple Health sync questions

Which fitness trackers sync with Apple Health?

Almost all of them: Garmin, WHOOP, Oura Ring, Polar, COROS, Fitbit / Pixel Watch, Amazfit, Xiaomi, Withings, Ultrahuman Ring, Wahoo, Strava, Peloton and MyFitnessPal write to it natively through their own apps; Suunto, Huawei and Zwift write some data types; Samsung Galaxy Watch needs a third-party bridge app. Each guide lists exactly which data types arrive.

Can I use two fitness trackers with Apple Health at the same time?

Yes. Apple Health keeps data from every source. When two sources record the same data type, such as steps or active energy, Health uses the source at the top of that type’s Data Sources & Access list, so the totals aren’t added together. Reorder the list to choose which device wins.

Why does Apple Health show a different step count than my tracker?

Another source, usually your iPhone or Apple Watch, is ranked above your tracker. Open Health → Browse → Activity → Steps → Data Sources & Access, tap Edit, drag your tracker’s app to the top and tap Done.

Do brand scores like Body Battery or Readiness sync to Apple Health?

Usually not. Apple Health stores standard data types such as heart rate, sleep, workouts and HRV. Scores a brand calculates itself stay in that brand’s app. The table in each guide shows what reaches Health.

Do workouts from another tracker close my Apple Watch rings?

No. Activity rings need a paired Apple Watch and update only from Apple Watch data, so workouts written by other devices appear in Health without moving the rings.

Is there an app that works with data from any tracker in Apple Health?

Yes. P.R.O. is a free iPhone app that reads Apple Health, so it works with every device that syncs there: an AI coach that answers with your real numbers, widget dashboards, training history for 50+ sports, adaptive training plans and a sleep score. Its free connector also lets ChatGPT, Claude, Gemini, Perplexity, Grok, Codex and Cursor read your Apple Health.
