### 3/5 — BUG REPORT

*2019-12-15*

I had posted to say that the app won’t work but in reality my kiwi scan tool has connection problems. Totally my bad.

### 5/5 — Scanner works well

*2019-06-15, version 2.2*

I use several scanners with my ELM-327.  This one generates a very detailed report showing the primary functionality of my 1999 Jaguar XK8 engine. Worth the money.

### 1/5 — Not working

*2018-08-18*

Waste of my money. Corn artists

### 1/5 — Avg fuel gauge confusing.

*2017-06-13*

Bought this app as it indicated a mpg reading. The reading on the app is confusing and doesn't offer any true readings. Indicated that I was avg 9mpg!!! 

Don't buy.

### 1/5 — Complete worthless

*2017-06-11, version 2.2*

A complete waste of money.  I would not recomend this even if it was free.

### 1/5 — Useless App

*2017-02-28*

Why there's a charge for this app, I don't know. It's done nothing for me. Waste of money.

### 1/5 — Waste o Money 2 (too)

*2016-12-21, version 2.2*

I beg forgiveness from the previous reviewer... I failed to heed your words... and I paid the price - the price of this app, to be exact! Same thing, it connects and reads the tachometer and that's about it. Says the trouble codes not in database/ couldn't read codes. This car is a newish Subaru afore crying out loud!!  It's probably the primary reason anyone gets an app like this. Don't fall prey to this app because it's cheap - it's cheap for a reason. DO NOT BUY THIS!!

### 1/5 — Waste of money!

*2016-11-22, version 2.2*

I want my money back! App reads out some things but does NOT out the DTC's which I the entire reason I bought it! Complete rip off

### 2/5 — obd2 scanner by bars

*2016-11-10, version 2.2*

Used to work good on all OBD2 equipped cars/trucks. Since iOS update 9 this app has never been able to scan older OBD2 SAE vehicles and has a hard time communicating with CAN equipped vehicles. Too buggy and I guess it was good while it lasted.

### 1/5 — Obd 2

*2016-02-20, version 1.81*

Will not connect to iPhone 6 Plus, don't waste your money!
