Amazing application. I used to be a career AV specialist, and this was beyond invaluable. Even in my every day life, it proves still to be invaluable. Worth every cent and I still use it almost every day.

Nothing worked or displayed properly on the paid version.

Great app, absolutely invaluable for anyone who works in A/V. Totally worth upgrading to pro, this dev team deserves it. Six stars!

Shows only "You currently have no favourites" on my Pixel XL, but no tools. This is sad, I really liked this ad. Ad version works normally. Please fix this, I'd be willing to help with additional information.

Very useful for an Av tech, good estimations of distance for projection has been very useful

Wow, for the price you can't beat it. I took the free version on a recent 2 city show and gave it a shakedown cruise. The only thing I found missing was some registration screen shots. Still had to use my ol' ppt alignment/ registration slideshow. Anyway, it does a lot in so little time without stupid banners on the bottom. You're out there like me making a living on this, guys so pay for the app! Suggestion to the developer: Please add in the "video" dept some screen resolution / registration shots. SMPTE colour bars.

Just bought and the very first tool using the tone generator failed and caused the app to stop working.
