I was checking out the Amazon App store the other day, because it JUST became available in Canada.
I came across this little app called Relax Melodies. Essentially, it’s a white noise generator. It provides you with a selection of many different kind of “sounds” which you can then mix and combine to create the perfect white noise for you. I’ve been messing with it today and it’s a great little app.
You can also find it on the Google Play appstore.
The free version here: https://play.google.com/store/apps/details?id=ipnossoft.rma.free
The premium version here (provides more sounds): https://play.google.com/store/apps/details?id=ipnossoft.rma.premium
And from the Amazon Appstore, if you prefer that.
