## Most critical reviews (6 lowest-rated)

### 1/5 — Horrible

*2025-04-22*

Won't stay connected.. connects then disconnects.  This has been an issue with this app going on 2 years.  A shame

### 1/5 — Works on Android

*2024-10-26*

All the features of this app work on my friends Android but not on my iPhone, it has hard or impossible to use most if not all features. All I can do is look at the trouble codes.

### 1/5 — Almost useless

*2024-08-15*

Bluetooth won't stay connected or just never connects.  Not sure why this hasn't been fixed.

### 1/5 — Limited use application when it works

*2024-08-02*

App doesn’t consistently see connected Bluetooth devise. Limited options for diagnostic. Can’t activate or remotely control engine components for testing

### 1/5 — Bluetooth tool will not stay connected

*2023-02-27*

Everytime you open this app it disconnects the Bluetooth from mobile device to diagnostic tool. $500 for the tool and not useful at all.

### 5/5 — Great for troubleshooting EFI

*2018-12-28*

I have been using this for a bit on my iPhone and it works great for troubleshooting and repairing efi’s engines. 

The dashboard for sensors gives everything I need in one simple display. 

No more bulky laptops bungee corded to the tractor.
