Best white noise app I've ever seen or used – Sleep Bug Review

I've been using this app everyday for over 4 years. It's the best. It's free, the sound is ongoing unlimited so it won't stop/shut off after let's say 12 hours, there's a great variety of white noise sound track options, it's easy to use, the sound quality is excellent at any volume, the volume range is great (you can choose from very soft to very loud), and there's optional variety you can add or remove to every sound track w/ the push of a button (for example, you can add seagulls to the beach waves track). My favorites: I play the waterfall at night for aiding deeper & better & uninterrupted sleep, and the beach waves in the day for relaxing & making me feel like we live near the beach! We have this app downloaded on all our devices, so it's mobile. The kids get the same white noise at home, in the stroller, car, at grandma's house, & on vacation!
