User Reviews

Users appreciate the app's advanced tuning features and helpful customer support, especially for certain bike models. However, recurring connection problems with the ECU, app crashes, and bugs severely impact usability. Display features like gear position and speedometer often fail or show incorrect data. The app also includes ads and paid features that frustrate users who have already invested in costly hardware. Overall, while promising, the app needs significant improvements in stability and functionality.

Cons

Frequent connection issues between app and ECU, causing data loss
App crashes on certain devices, especially when rotating screen
Missing or malfunctioning displayed information like gear position and speedometer
Paid features feel like an additional cash grab after expensive hardware
Buggy functionalities such as quick shifter settings and calibration saving

Recent reviews

The app doesn't display gear position, speedometer (sometimes it shows but not correctly) and the app response is slow, sometimes it doesn't send data to the ecu. I also miss some of the original features like one push start.
