### 1/5 — When is the update???

*2023-08-03, version 2.0*

App crashed when I tried scanning vehicle

### 1/5 — 30 second limit

*2023-07-04, version 2.0*

Works for about 30 seconds on my iPhone 14 pro, then crashes.  Already bought a replacement and it isn't Gopoint.

### 1/5 — Fail

*2023-01-24, version 2.0*

This app and device was working great in the pass but does not working anymore.

### 5/5 — Need update

*2022-12-05, version 2.0*

Seems to be crashing since IOS 16 update. Please push out an update 

Works perfectly as advertised until IOS 16

### 1/5 — Garbage app, garbage hardware and garbage company

*2022-02-26, version 2.0*

Garbage app, garbage hardware and garbage company. Why this app is allowed on iTunes App Store is beyond me.

### 1/5 — Broken

*2019-02-28, version 2.0*

Doesn't let you select a make / model and you cant select this step

### 1/5 — Waste of money.

*2018-04-12, version 2.0*

Worst scan tool I’ve ever owned, the software is never updated for newer vehicles, has no live data stream, constantly running into glitches and apps closing involuntarily , I purchased the cable, the Bluetooth OBD2 BT1 and the software which now no longer works at all because it’s not compatible with the newer versions of IOS. Steer clear of this scan tool. Steer clear of GoPoint technology inc...

### 2/5 — Doesn’t Work on my iPhone X

*2017-12-02, version 2.0*

Worked ok with the 6s, but can’t connect with the X. 
Getting error message “Initialization failed “
Anyone has a solution?

### 1/5 — Garbage

*2016-06-16, version 1.3.1*

The box the device comes in says "works with ipad, ipad2, iPhone3G...." but you cannot install the app onto a 1st generation iPad because you need ios7+. You can't put ios7 on a 1st generation ipad. There is no other option so this is just a major waste.

### 4/5 — Prius

*2015-08-16, version 1.3.1*

Great
