100% failure - complete waste of money

The app connects to your Bluetooth heart rate monitor and you start a 55 second Heart Rate Variability scan. During the scan, the app fails, loses connection to the heart rate monitor, 100% of the time. It fails 35 seconds in most often, then 45 seconds in. When it fails you must start over, and after 4 weeks I have yet to success get a scan.
I have followed all of ithletes suggestions, including importing the heart rate monitor from the UK that they recommend. My skin under the pads has been dry, with the gel, with water, with water and salts, pre workout, post-workout and the app fails every time.
Ive written in for support and zero response.
In summary;
- app doesnt perform the one task it advertises
- support is non-existent
- waste of $10
- waste of my time.
