## What is AV Aid toolkit?

Useful tools for the Audio Visual technician! 

When you connect your device with a VGA adapter, HDMI adapter, or Airplay to a projector or flatscreen monitor, AV Aid will detect and display all available output resolutions for your device. (Even 4K!)  You can then select one of these custom resolutions and AV Aid will generate and output color bars or mirror test patterns onto your display.

The audio test generator is also expansive, including left, right, center, phase test, pink noise, white noise, sweep, a test song and more.  You can also designate your own custom test song from your own music library or via Apple Music.  *AV Aid now features a Dolby 5.1 and 7.1 surround sound test using ec-7 (enhanced ac-3) encoding!

There are several other handy AV features like flashlight, IR detector, TRS, XLR, CAT-5 Pinout reference, cable connector resource guide, and additional tips for troubleshooting Audio Visual systems. 

We have now also added a full screen front and back camera view if you would like to use your mobile device as a document camera during online meetings.

*2026-01-30*

A fb! Empty

### 4/5 — Awesome App but one Wish

*2026-01-19*

Awesome app! Would be great if we had the ability to change resolutions on the fly and check 30hz / 60hz.

### 5/5 — Used daily as indie recording engineer to sort out the vagaries of indie studio wiring

*2022-05-13*

Thank you!

### 5/5 — Coworkers use regularly, I’m concinced

*2022-05-10*

Very useful app for a 5 star environment. Makes it easy to test a set or troubleshooting in front of clients. I will use the app from my home screen so that I can throw up a test pattern with no effort. Very useful. All the audio features and guides are a huge plus as well. No need to do a search for content to test your set.

### 4/5 — Useful, but

*2022-01-01*

This is a useful tool, but I wish there was some way to send a 16:9 signal for setting up projectors.

### 5/5 — Very Useful Tool!

*2021-11-26*

I am an A/V installer and this app is fantastic. On an iPhone, get the HDMI to lightning adapter coupled with this app, and you can do some very useful video tests. The audio is powerful as well. On church installations, I use the pink noise generator to EQ the room. Well worth having this app if you do any of that type work. It is so convenient, sometimes I forget I have it, walking to the truck to get test equipment I don’t need. I already have it!

**Developer response:** Hi VideoRex!  So great to hear that it’s working out well for your application.  Thanks for the awesome review and let us know if we can do anything to make it even better!

### 5/5 — Great app

*2021-08-17, version 3.1.1*

Everything you need to test a system in 1 App. Perfect!

### 2/5 — Not compatible

*2019-10-18*

The audio tools not compatible with iPhone XR

**Developer response:** Hi Goran, so sorry to hear this.  I believe that this was resolved in a recent update, but I will look into it to be sure. Apologies for the excessively late response. Your message somehow slipped my radar, but it sort of makes sense since my wife had our second child around that time.

### 5/5 — Great App - very useful

*2019-02-09, version 2.3.2*

Would like to see a Lip Sync test
Would be nice if the 5.1 and 7.1 looped - app ends after one test
Also like to see more info on HDMI and Display port e.g. bandwidth, max resolutions supported.

### 5/5 — System Commisioner

*2019-02-02*

It is my main video test device. You can verify HDCP compliance via iPhone HDMI adapter. You can verify video audio levels passing threw AV switch to DSP. Awesome app.
