FAQ — Frequently Asked Questions
Which devices are fully supported (live heart rate)?
Full support means your heart rate shows up live in the trainer's cockpit during a live session. It works with any Bluetooth sensor broadcasting the standard Heart Rate profile (BLE) — an open standard, not a list of one-off integrations. In practice that means chest straps and arm bands.
Known to work: Polar H10 / H9 / Verity Sense, Garmin HRM-Dual / HRM-Pro, Wahoo TICKR, Coospo H808S / HW807, Magene H64 and most BLE arm bands. If the product page says "Bluetooth Smart / BLE heart rate", it will work.
Will my smartwatch or fitness band work?
Most smartwatches and bands (Samsung Galaxy Watch, Xiaomi / Mi Band / Amazfit, Huawei, Fitbit and others) don't broadcast live heart rate over the open BLE standard — they keep the data inside their own apps, so they can't stream it to the trainer's cockpit during a live session.
Exception: many Garmin watches have a "Broadcast Heart Rate" mode — once enabled, the watch acts like a strap and works live. We continuously develop and test new sensor groups to offer the best solution — without tying the app to third-party apps — so the list of supported hardware keeps growing over time.
Do I need a third-party app or account?
No. TrainHub connects to the heart-rate sensor directly over Bluetooth — you don't need a Google, Samsung or Garmin account or any companion app, and your heart rate never passes through third-party servers.
We deliberately don't tie the app to third-party platforms — instead we continuously develop and test new sensor groups to offer the best, most reliable solution right inside TrainHub.
I don't own any sensor — is the app still worth it?
Yes — a sensor is optional. Without one you still get full workout plans with set check-offs, a calendar with weekly streaks, nutrition plans broken down by ingredient, progress photos with a comparison slider, trainer chat and offline mode at the gym. Live sessions with your trainer work too — just without the pulse view.
