Sleep Bug Pro

Sleep bug pro allows you to create the perfect sleep sound, by adding or removing certain elements, and you are able to adjust each sound. Makes sleep bug pro the number 1 in my book for white noise to sleep by

There are 24 different categories of sounds to select from. Within each category you can choose to add subtle sounds. For example, in "music box" you can add subtle piano in the background. In "ocean" you can choose to add whale sounds. There is a sleep timer and the clock is displayed. I have tried several sleep sound apps and Sleep Bug Pro is worth the purchase. Pair your phone to a Bluetooth speaker and take really get lost in the sound. Not only for sleep, you can meditate, study or have white noise in the background to help concentration. Works perfectly on my Nokia 1520 (8.1 Denim).

I love!!! it helps me sleep!

Excellent selection of mixers and sound effects. You can even set times so it'll turn itself off. If you would like to figure out if it's worth purchasing, look at the regular Sleep Bug app first. One issue with the app is that it won't run in the background - you can't, for instance, turn it on and then go navigate away to read your emails or something. The sound will cut out. It's perfect otherwise.
