Here is my first feedback on your app.
Graphics are nice and smooth.
The app looks promising.
For easy riding, when I drop down gear, the RPM display number become way too low compared to reality.
Sensor connections are not stable. Either my BPM sensor is droped or my Tacx Flow. Sometimes it reconnect automaticaly, sometimes not at all.
My main concern is sensors disconnection as I’m not able to complete any training session or even the FTP test.
