I use this app almost everyday – Brainwaves -- Binaural Beats Review

Pretty cool! I purchased the lifetime package before my one month free trail expires. Coz it’s what I was hoping for! I just listened for less than 5 minutes the first day I downloaded it, I feel asleep immediately and never woke up through the night. Since it can be used in 5 devices, I have recommended this to my grandpa. He enjoys this app too, cool!
