## Most critical reviews (10 lowest-rated)

### 1/5 — Doesn’t connect to Veepeak OBD

*2024-04-14*

Screen just sits on The Connecting Devices page and never shows anything. I can connect to my Veepeak plug in tool just fine with OBD Fusion. No help is provided. And attempts to send Bug Report fail because it says I don’t have email set up in my phone.  Oh well. Was gonna try this tool for battery registration.

### 1/5 — BT connection shoddy

*2015-11-16*

BT connection stays connected for about two minutes when opening the app for the first time. It then proceeds to drop and reconnect every 15-20 seconds after that. Iid Tool is up to date.

### 2/5 — Missing things

*2025-07-18*

It drops items from the car randomly.  No low fuel light since using, other items have come and gone, then back.  Connection is not consistent enough to not cause issues

### 3/5 — Live Values Do Not Work

*2021-01-18*

The app works well for service functions and pulling faults, but the Live Values feature simply does not work: you can select different parameters but they always show N/A, and if you enter into the Chart mode, there’s no way to exit - tapping “End” does nothing.

### 4/5 — Incredible Granular Control, Antiquated UI

*2024-02-24*

I couldn’t be more satisfied with the amount of information and control the app provides, but would very much like to see an update from the developers that focuses on a updated interface. 

As it stands, the interface resembles an app from the early days of Android OS. I don’t mean for this to be a dig so much as an observation.

### 5/5 — Indispensable Tool

*2024-08-23*

If you’re into secondhand+ Land Rovers like I am, buy the Gap Diagnostic tool for which this app is a convenient and easy to use interface. If it saves you just one trip to a mechanic it pays for itself!

### 5/5 — Superb app, brilliant service

*2021-03-11, version 3.1.4*

If you have a 2002-2012 Land Rover, the IIDTool is a must for diagnosis and programming. Functionality is superb and the support backup from the team at GAP is amazing.

### 5/5 — Brilliant

*2017-05-08, version 2.9.4.5*

Highly recommended diagnostic tool with excellent after sales support

### 5/5 — Brilliant app/product, won't leave home in the Range Rover without it

*2017-03-13*

Amazing product and support from the guys at GAP Diagnostics, always willing to help and respond to questions etc..

### 5/5 — Amazing

*2016-11-13, version 2.9.3*

Multiple live values and graphs plus ccf editing, this app is amazing.

## Most praised reviews (2 highest-rated)

### 5/5 — Great potential, looking forward to updates.

*2014-11-05, version 2.2.4*

Currently the app does little more than is possible with the non blue tooth version and the Land Rover display.

However, we're promised graphs, multiple live value displays etc. if and when they arrive, the app will get five stars from me!

[Update May 2014]
Still waiting for the promised update. 
Is it vapourware?
[Update Nov 2014]
Awesome tool since v2
Seeing the live values is very impressive along with the diagnostics.

### 5/5 — Range Rover SC - Love

*2014-01-17*

Well, this is one great app for connecting to the black box also provided by GAP. Beats using the stalk controls! Saves the cost of a single trip to the Land Rover dealer and very easy to utilize. ;)
