### 1/5 — Waste of money

*2021-01-10, version 11.0*

Would not connect to the reader. Downloaded a free OBD2 app that worked well. $22 down the drain.

### 1/5 — Não é compatível com BlueTooth

*2020-05-09, version 11.0*

O desenvolvedor não avisa que não é compatível com BLUETOOTH. O app exige uma interface ODBII com WI-FI!!! Quero meu dinheiro de volta.

### 1/5 — Doesn’t connect

*2020-03-01, version 11.0*

Causes phone to reboot when trying to connect app is useless

### 1/5 — Waste of money

*2020-02-16, version 11.0*

Keeps crashing. Anytime you go to access any feature just crashes.

### 1/5 — Junk

*2020-01-26, version 11.0*

Does nothing but disconnect or spin once connected. Junk

### 1/5 — Not good

*2020-01-21, version 11.0*

Do not buy

### 1/5 — Waste of money

*2019-12-27, version 11.0*

Freezes on iPhone X - doesn’t work at all

### 2/5 — Poor support

*2019-12-17, version 11.0*

Contacted via email for support on 2 occasions and I did not receive any responses. Requesting a refund because I can’t use an app that doesn’t provide any support.

### 1/5 — Cannot recommend it weakest feature set

*2019-12-11, version 11.0*

Bought it on the promise of Torque Pro that is so popular on Android. This is barebones app to the point it is useless. No special codes for a lot of the vehicles. Just wasted $10 on this. Go OBD Fusion if you need logging, reporting, etc.

### 5/5 — Getting app!

*2019-12-10, version 11.0*

Wonderful
