### 2/5 — Organization

*2026-08-08*

Please make it possible to have the parameter list organized by numbers going from lowest to highest like the android version as it’s far more convenient when setting up a new board. Also it’s very inconvenient that on the iPhone app whenever a value is changed it kicks you back out into the menu screen

### 1/5 — Worst app to use to set up unit

*2025-12-03*

Unfortunately you don’t have a choice but to use this terrible app. It took me forever to get the app to connect to the unit. And after an hour of trying I ended up having to call their tech support.
