Great app...needs some tweaks

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....

Helpful mobile resource

This is a great AV resource for technicians to reference while on the go. The main page randomly displays explanations of common AV terminology.

Will not open on 2ndGen 12”iPad Pro.

I was very happy with this app for the time I used it on my Apple iPad Air2 which I replaced with my iPad Pro proximately a year ago. 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.
