Not sure why the app is non-functional, will not download or update. I hesitate to apply any further funds with a developer that may or may not support 1gen apps after the 2nd gen is released. **Developer response:** Hello, Sorry to hear you are having trouble with AV Buddy Pro. We are updating the app at the moment to match the new updated AV Buddy. Hopefully will not be long untill release. ### 4/5 — Great app...needs some tweaks *2018-01-29, version 3* Great little app that has a lot of useful reference material tread in, and testing apps. The site survey potion is nicely done, but could use the ability to add more than 2 pictures.... curious if the developer plans on adding features/updates.... ### 5/5 — Amazing app for professionals and amateurs *2017-08-28, version 3* Well worth the amount of money! Thanks man! For the developer: I would love to get a lens calculator for Panasonic projectors. Also loved to see a power section (for distros, socapex, etc) and a lighting section (for DMX, fixtures, etc) ### 4/5 — I like It *2015-04-21* A good useful App which collects together many of the details that I may need occasionally. It is clear and easy to understand. Please add the ability to output audio test tones through the output jack. The projector datasets may well need updating and please add datasets for Panasonic projectors. Ta, Lol ### 5/5 — Amazing App! *2014-05-15, version 2.2* If you do any type of A/V, be it commercial or residential, you need this app! It should be considered one of your tools. Absolutely perfect for testing -- you don't need to lug around all your testers, just your phone VGA/HDMI adapters and this app! Thanks Chris! ### 4/5 — Mr *2014-02-17* Some fantastic tools and information. Still can't get the microphone working on iPad or iPhone on iso7! ### 4/5 — Helpful mobile resource *2013-11-05, version 1* This is a great AV resource for technicians to reference while on the go. The main page randomly displays explanations of common AV terminology. ### 5/5 — Good job ! *2013-08-07* This app has so many features ..! Useful, organized and accurate references. What you need and when you need it ;-) ## Frequently asked questions about AV Buddy Pro ### What is AV Buddy Pro used for?
