What's New in Moss

1.4.0

October 19, 2026

Moss is now made for iPhone Duo. Open it up and Moss uses the whole inner screen, with the orb on one side and your sounds and sliders on the other. Fold it partway and nothing sits on the crease. Moss can also share the screen with another app. Small fixes throughout.

User reviews

One of The Few

This is one of the few noise generation apps that has listenable white noise. Everything is so soft - and the slider option for fine tuning is great. It’s generated on the spot instead of a file being played back which is what most “generators” really are. The only Green noise app I can find that has such high quality and accurate noise generation. Comparing the tone to other soundscapes, the tone of the noises provided in this app are highly accurate to natural recordings while still being noise from a noise generator. Great stuff. Great to listen to, and soothing. The Green noise specifically reminds me exactly of wind in the mountains for our summer trips. Exactly the right tone.
