Exceptional tool for every day PA use. Lot of effort has been put into this and it shows.

Wow - almost everything is here for helping with live sound. Well presented and good help info.

So many useful tools here. Pretty much any conversion you would ever need to do, this will now do the heavy lifting.

This app says it needs access to my camera. Why? Tried to contact the developer via "Feedback", but there seems to be a problem with his email verification system that proves I am not a robot. I followed the instructions, but it just sent another verification email.

Did what I needed from it.

All very good having all the calculators. Very useful. But, the interface is just too slow to use in a gig situation. All those fancy fades and transitions are unnecessary and distracting. Just take me to the page I want. Also, who puts an intro on a calculator app? Just wastes time and is annoying.

At last an app for android that does a range of audio calculations. Does what it says on the tin!

A really useful 5-star audio toolkit, but spoiled by the interface - unlike the website version you have to go through 6 screens before you get to the calculators - similar apps like ElectroDroid take you to the calculator you want with a single touch.
