This app is cool and the fact that you can dial in your own frequencies but it does not play with other apps. Also when you turn it off for more than a second it makes you go back and reset all the parameters. Needs work folks.

I thought this was a really great app and the best part is there are no in app purchases - completely free. If you know which tones you want to play (i.e. 432hz etc) then it's great for you. If you don't really know anything about binaural beats the app itself doesn't go a good job of explaining but that's nothing a simple google search on the various popular binaural tones can't fix. You put in the higher number for the carrier such as 432, and then a lower number for the tone like 30. You can have it play for as long as you want set on a timer. Awesome thanks guys.

Awesome app! Allows the manual entry of the exact desired beat frequency and carrier. The only drawback is that you have to re-enter the parameters every time the app is opened or interrupted by other apps. Would be MUCH better if favorite settings (memory) was available in the app. Highly recommended for users who are familiar with the various binaural beat frequencies and associated carriers.

I explored every aspect of this app. Don't waste your time, look elsewhere
