Device Compatibility
AxnPoint WrXs reads heart rate from the industry-standard Bluetooth Heart Rate profile. If a sensor speaks that standard — nearly every chest strap and armband sold today, and any sports watch with a “broadcast heart rate” mode — it works. No brand lock-in, no dongles.
Built in: Apple Watch and Wear OS
The AxnPoint WrXs watch apps install automatically alongside the phone app on Apple Watch and Wear OS. Nothing extra to download — open the app on your watch, join the session, and go phone-free with live zones and haptic alerts on your wrist.
Bluetooth sensors: iPhone today, Android returning
Straps, armbands and broadcast watches currently connect through the iPhone app. Android support is returning in an upcoming release — in the meantime, Android members can go phone-free with the Wear OS watch app.
Chest straps — best accuracy
Any Bluetooth (BLE) chest strap works. Widely available choices:
- Polar H10, H9
- Garmin HRM-Dual, HRM-Pro / Pro Plus
- Wahoo TICKR, TICKR X
- Coospo H6 / H808S, Magene H64 / H603
- Myzone MZ-Switch (in Bluetooth mode)
Optical armbands — no strap under a gi
Comfortable for martial arts and easy to share between members:
- Polar Verity Sense, OH1
- Scosche Rhythm24, Rhythm+ 2.0
- Wahoo TICKR Fit
- Coospo / Magene armbands
Connecting a strap or armband
- Put the sensor on and wake it (most wake on skin contact or with a button).
- In AxnPoint WrXs, scan your gym’s QR code, then under Connect from choose Bluetooth sensor.
- The app finds the nearest broadcasting sensor and connects — you’re live on the board in seconds.
Sports watches with “broadcast heart rate”
Many sports watches can act as a Bluetooth heart-rate sensor. Turn the watch’s broadcast mode on, then connect in the app exactly like a strap:
GarminMost recent Forerunner, Fenix, Venu, Instinct and vívoactive: Settings → Sensors & Accessories → Wrist Heart Rate → Broadcast Heart Rate. Models older than roughly 2019 broadcast ANT+ only, which phones cannot receive.
PolarVantage, Grit X, Pacer, Ignite: Settings → General settings → Pair and sync → Heart rate broadcast.
COROSPACE, APEX, VERTIX: open the toolbox/menu → Broadcast Heart Rate.
AmazfitNewer Zepp OS models (GTR 4, T-Rex 2/3, Cheetah): enable heart-rate broadcast in the workout settings.
WhoopWhoop 4.0 and later: enable Broadcast Heart Rate in the Whoop app’s device settings.
SuuntoRecent models (Race, Vertical, 9 Peak Pro) can broadcast; older Suunto watches cannot.
Not compatible
- Fitbit and Oura — they never expose live heart rate over the Bluetooth standard.
- ANT+-only sensors (older Garmin straps, some gym equipment) — phones have no ANT+ radio.
- Myzone MZ-3 — proprietary protocol (the newer MZ-Switch works in Bluetooth mode).
Good to know
- A Bluetooth sensor connects to one phone at a time — it can’t feed AxnPoint and a treadmill simultaneously.
- Watch broadcast modes usually need to be switched on for each session.
- Blood-oxygen (SpO₂) readings come from the AxnPoint watch apps only — straps and third-party watches provide heart rate.
