I have tons of Apps for helping with relaxing, stress, etc., & this one I think is still my favourite, Im SO HAPPY I found this App, I do use some of the others I have, which in total is about 10 Apps, using Brainwaves, with music, or sounds to do a variety of things, But still this App I always end up going to, when Im trying to wind down to go to sleep especially!! It is the BOMB!! Its worth every penny I spent on it & now knowing how well it works I would pay more!!
