### 4/5 — I can not connect

*2020-09-20, version 1.2.2*

Hello!  On my phone version ios 13.6.1. I cannot connect to the adapter.  Please correct this error.  It is advisable to focus on the new ios 14.

### 3/5 — Defi master c

*2019-08-06, version 1.2.2*

Best program, please make it on English language.

### 1/5 — 👍🏻

*2017-03-11, version 1.2.1*

Since updating this app opens upside down every time! My iPad is mounted in my dash and this makes using the app useless. Please fix Defi.

Please add iPad support so the app fills the whole screen just like it does on the iPhone. 

This app is great with instant response. I've build my whole car gauge display around this app and using the Advance Controller with an iPad mini built into my dash fascia.

### 1/5 — when to ver update?

*2016-04-30, version 1.1.2*

when to ver update? ios 9.3.1

### 1/5 — iOS does not support BT

*2015-12-20, version 1.1.2*

This looks like it would be a KILLER app if iOS was to work with BlueTooth OBD readers. WiFi OBD readers only work with iOS so this app is totally useless.
