### 1/5 — Help

*2020-09-29*

### 1/5 — Doesn’t work with all radios

*2020-07-15*

had great hopes for this but doesn’t work on all radios after app is open and you begin to play a test tone audio muted and switched to I tunes tried to switch back  won’t play tone tried a iPad with no music on it and same thing plays about 30 seconds and muted get no playable media on usb message 
Tried this on several ford sync systems with same results

### 5/5 — Perfect tool for tuning audio

*2022-01-28*

Love this. I was told about this app earlier today and have used it for two cars so far. How great is it to have pink noise in an app with so many ways to use it. The best part for me is the fact that I can easily move between this noise generator and the music app to compare the RTA tune to real music. I can see this being an invaluable addition to my tuning toolbox.

### 5/5 — What a great tool

*2022-01-20*

The mastermind for this app should get his own gold star. What a great tool that you always have. It’s useful as a sales tool and for any installer that takes his job seriously. Kudos to the team at education for a truly bad to the bone tool!!

### 5/5 — A must have tool !!

*2020-07-12*

Great tool that allows an audio tech to complete many tasks, and comes in really handy specially when dealing with vehicles that don’t have a CD player. 
Well worth the investment.

### 5/5 — This is a installer must have app

*2020-07-12*

This is a great app for any professional installer. This app will save you so much time on tuning a new sound system.

### 5/5 — A must have for any 12Volt audio specialist.

Please add CarPlay compatibility!

**Developer response:** Hi, thanks for the kind words - we did test on CarPlay prior to launch and confirmed operation from the handset (we do not have the UI on the CarPlay screen at present). Can you confirm if you have operation from the handset touchscreen? Thanks!
