Im withholding the fifth star in hopes that the option to listen to music from my personal collection (via the music app) is integrated. iPhone allows one sound source to come through, so I cant background it. The tones in this app are the most effective Ive used. The sound effects provide just enough ambient distraction to allow the tones to insinuate themselves without you focusing on them directly. The app is nearly perfect. Aside from my first request, the only other thing is love to see is more isochronic programs. I love that the app has ones for daytime listening, even at work. They are effective and useful, especially if listened to at the same time each day. The rhythm seems to be the key. As a far off possibility, the ability to record suggestions would be swell too. Sub vocalized suggestions, in repetition, especially in your own voice, can have similarly interesting effects as the tones. The app is worth every penny of the in-app purchase. If you like this sort of thing, and are consistent enough for it to make a difference, this app is a one stop shop.
