A smart watch is what streams your heart rate: Apple Watch with iPhone, Wear OS with Android. You can still record video and use the gym board without one.
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.
iPhone: your weight, height and body fat sync from Apple Health.
Android: enter your weight and body composition in the app — it is saved to your training history.
Record video, review your session and use the gym board without any wearable. Heart rate, zones and calories need a watch.
