### 1/5 — Virtually Useless

*2022-12-14*

This app is virtually useless. The first big is inconsistent access to the tri-bar menu button. There’s some odd swip or tap gesture required to get it to show up, however; even if you can - which most times you can’t because the gesture is too similar to “tap to change the gage face style”, the menu button is too close to the edge of the screen and the touch doesn’t register. 

Shameful on a pretty clean app with lots of useful features. 

I appreciate that my odd ball nexus Bluetooth dongle worked perfectly with the auto connect feature. Once you do connect be sure you got all the adjustments out of the way because good luck getting the menu to to be accessible again.

### 1/5 — No connection

*2022-09-15*

Can barely get a connection and once connected, no PIDS are supported. Either faulty live spec or something going on with the app.
