### 3/5 — What are you waiting to develop a CarPlay compatible app??

*2026-05-23*

Hey guys what are you waiting to develop a CarPlay compatible app?? It’s kind of basic to have nowadays those engine values in the screen of the car while you race!

### 1/5 — BMS doesn’t care - App is garbage

*2026-01-14*

For anything Jeep/Dodge/RAM/Alfa Romeo/Maserati this app is absolute garbage and BMS does not maintain it well. Get ready for limp mode!

### 5/5 — Data logging

*2025-12-25*

The app and data logging works great just like the mobile, but I’m on platform 125 (2.5T smartstream kia/hyundai) and for whatever reason when I’m reading a data log, it does not give me the option to enable cylinder one or “ign1” to see timing for cylinder one it’s not even in the options. List to be enabled when reading a data log.

### 4/5 — Good app, some bugs

*2025-10-20*

Overall this is a great app. It could be easier to identify which firmware profiles you need and how to make changes. Clearing DME codes doesn’t work consistently. And it would be amazing if this could be CarPlay compatible, even just a gauge widget. Allow volunteers to help with Dev!
