Wow this looks incredible! I quite like the Overcast model where you can optionally pay a little just to support the author rather than for extra features or nagware.

So I made Ambi, a small iOS app with a clean interface and a set of freely available ambient sounds — rain, waves, wind, birds, that sort of thing. You can mix them, adjust volume levels, and just let it play all night or while you work. Everything works offline and there are no hidden catches.
It’s something I built for myself first, but I figured others might find it useful too. Feedback, bugs, and suggestions are all welcome.
