Neuro Sequencer Pro

One star off because it has no background functionality.

This is an excellent program for binaural beats and Isochronic tones. The program is responsive and versatile, and you can create and export your own programs!

It was good when it worked. I purchased. It crashed. Now it thinks it's a demo again. Can't reinstall to fix.

Superb! Perfect! Exporting songs lets you listen in background.

Coming from a person who needs "SOMETHING" to study, focus, sleep! This is the app that has that "SOMETHING." I have tried between 10-20 other apps but nothing works like this. At first the simple, warm tones feel weird but give it a try, let it fill your mind! Dont just listen to it for a minute or two and press the stop button. It takes time for that "SOMETHING" to kick in but once it does you will understand what I mean. Soft, calm, mellow, dreamy, introspective- are a few words to describe it.

Expensive and no background, otherwise very good
