### 1/5 — Crashbot

*2020-05-05, version 1.23*

Crashes every time it connects to my HR monitor. Tried reinstalling, restarting, still crashes.

### 1/5 — Still crashes

*2020-01-26, version 1.23*

Can’t update my Lezyne HR monitor because this app crashes every time it connects to the HR sensor.  This app is garbage.

### 1/5 — Crashes

*2019-10-05, version 1.23*

Crashes as soon as it connects to the heart rate monitor. I did get this to work on Android though but ok to would not work on iPhone or iPad. Buggy software unfortunately seems to be a theme with Lezyne. Too bad. I like their hardware but their software leaves much to be desired.
