*2026-07-07, version 1.1.3*

Please don’t waste your money

### 5/5 — I'm cool with it

*2026-05-25, version 1.1.3*

I been using it some atleast 4 years now and it works perfect for what I need it for. The codes are true to the devices knowledge. It found my problems on my 08 gmc Yukon saying #5 coil was bad and after replacing it fired perfect. And it also is showing other codes that I know for a fact need changing but yea ish work good. Also I used It in my brother 2025 Honda and helped others figure their problem out

### 3/5 — Not best Not worst if it’s free it’s worth it

*2026-04-18, version 1.1.3*

The scanner tool dosent do everything they say it does and can’t read all cars or as smart as it makes it sound try to find a scanner that’s bi direction and updated toc2026

### 5/5 — Software is super easy to use

*2026-03-24, version 1.1.3*

Was able to connect my OBD2 reader to my iPhone with this app without any drama.  The app seems to do what we need and it is very simple to use.

### 3/5 — Works kinda

*2025-12-03, version 1.1.3*

Every time I go to look up technician service bulletins or recalls and half the time live data is nonexistent like to see some improvement

*2025-09-11, version 1.1.3*

Good

### 2/5 — Scanner/App

*2025-08-05, version 1.1.3*

Scanner works GREAT the app is okay my only complaint is you can’t switch between metric and imperial measurements when looking at live data all temps are displayed as Celsius and can’t switch to Fahrenheit

### 1/5 — Dont waste your cash

*2025-07-31, version 1.1.3*

Other than seeing some basic live info, such as Engine RPM and temp etc this is pretty useless. Doesnt display any error codes. Cheap nonsense thats just a waste of cash. Tried on Mitsubishi, BMW and VW Golf.

### 1/5 — 0 errors. While my dash display errors

*2025-05-22, version 1.1.3*

How comes that my car shows me issues and your app none. Reads everything except main thing. Another trash

### 1/5 — Malísimo

*2025-02-17, version 1.1.3*

No sirve el menú está en chino. No se conecta por Bluetooth. Ni que intentes mil veces. No sirve mala calidad. 
No lo recomiendo. No poerdas tu tiempo.
