Review summary

Recurring feedback centers on stability and connectivity issues after updates. Many users report crashes and the app failing to pair or connect with the OBD device, preventing core functions like reading codes. A minority praise the hardware for fast, accurate readings, gauge display, and battery voltage monitoring when it works. Overall sentiment is negative due to reliability problems, despite some positives when the app operates as intended.

Fast and accurate readings when the app is functioning
Ability to view gauges in the app
Battery voltage monitoring feature

Cons

App crashes or becomes non-functional after updates
Bluetooth pairing/connection failures with the OBD device
Inability to scan/read codes or enter VIN due to app instability

2022-10-24	BC*****	Other apps can view but not link to the M2, so I know it works. Can’t test somethings function if your own app doesn’t pair with the device. Fix this app!!!! If not, it’s wasted money.
