What our customers are saying
Interesting Data!
The data I get from this device is super interesting - in particular continuous traces during exercise, breathing rate, heart rate and HRV. It’s fascinating to exercise and leave the device on for an extended recovery period. The graphs and charts in the web app make it easy to look through your workouts and see where you pushed yourself and how your body responded. Comparing HRV changes before and after exercise is interesting and helpful for exercise programming.

Easy to use, easier to analyse!
Directions were easy to follow, quick to set up and get started. I liked that the Bluetooth connection works very well and consistently. It is pretty comprehensive, it will tell you % time spent on various heart rate zones, average heart rate, strain, beathing rate, heart rate variability and step cadence as well as % of heart beats that have a normal pattern vs abnormal.
YT
Registers excellent ECG quality
The device works surprisingly well. It produces a nice, stable single lead ECG approximately equivalent to V5 even during heavy training sessions. The online app adequately indicates premature ventricular beats and bigeminy. A registration during several hours at rest nicely shows the influence of caffeine or alcohol intake on the occurrence of premature beats.
ALFRED APPEL
Best ECG and HRM on the market
While this device is useful for the athlete, it is imperative for the cardiac patient. Think apple watch on steroids, this is it! Instead of a 30 second glimpse into how your heart is doing, you can record your ECG for over 24 hours, and post-process that data using their web interface for every SINGLE heartbeat. You can share your live ECG in real time too. Great for getting second opinions remotely.
