### 5/5 — Does what it’s supposed to do.

*2024-12-02*

I’m grateful the creators still update this app. I’ve had the device and app for years now. I don’t always need it, but grateful when I do.

### 1/5 — Terrible UX

*2022-10-22*

On iOS 16 gestures are not supported. So it’s quite difficult to switch apps. The UI in general is not intuitive and seems thrown together. There does not appear to be any EV  support.

### 1/5 — Doesn’t work properly on iPhone 13

*2022-04-15*

It starts up on my iPhone 13, but then shuts down after a few seconds.

### 4/5 — Great tool

*2021-10-19*

I’ve owned this device and app for about 4 years.  It’s the first app of this kind I owned.  You can read and clear codes, read settings as dials, bars, and graphs.  Being able to monitor O2 sensors with a graph in realtime tells you exactly what’s going on.  It even had a PID for my Ford F-350 6.0 diesel.  It works on all 6 of my vehicles, Fords, GM, Saturn, Hyundai, and Pontiac.  It’s well worth the money.

### 3/5 — No wifi.

*2021-10-05*

Should say BT only

### 1/5 — Язык

*2021-02-06*

Русский язык где???!!!верните деньги!

### 5/5 — Worked Well

*2020-12-29*

Was able to clear codes on a Ford Focus MK3 with no problems

### 5/5 — Great cheap option

*2020-09-22, version 2.3.1*

Out of all the OBD readers this is the easiest to use. It may not fully work if every vehicle but it’s great at pulling codes. Worth it!

### 3/5 — 直ぐに繋がる

*2020-04-28*

他のアプリより、確実に繋がります。
無料版は僅かしか表示しません。
これらのアプリは有料版でチェック出来ず、折角良いものでも惜しい。無料版で制限事項を明確に示して呉れるとありがたい。

### 1/5 — Terrible app and adaptor

*2019-11-14*

Literal garbage app. Connects to LeLink but doesn’t display any data. No setting to adjust. Absolute junk. Will be returning the adaptor
