IOS8 Issue

Has stopped working on IOS 8 it just freezes and doesn't let you use any features

Great Job!

This app does exactly what was looking for and it looks minimalistic, the white on black makes it look sleek and not too bright for when I'm working on music late at night. Perfect for me :)

Very Simple but effective

Helpful tool to use either as a tone reference, for when I'm tuning guitars or as a tone generator.

Very useful app

Great app for sound techs or musicians, in need of perfect pitching or wavelength calculation. Much quicker then a calculator for working out spacing in a sub array, which is what I use it for.

I like it ... A lot.

Great app and essential for anyone working with audio. I used it to sort the intonation on my acoustic guitar today; much quicker and more accurate than using a microphone-based guitar tuner. It also works well as a synth, though I don't think that was the intended purpose for this app ;)
