Users generally praise Pero for its broad ambient sound library and calming effects, with a well-designed favorites feature and solid free content.

Some users also wish for more updates or visuals, but the dominant feedback centers on improving free access and library depth.

Cons

Limited free options and a paywall; more free options desired.
Desire for more sound selections/variety beyond what's currently available.

Recent reviews

The free version should have a sound that everybody would like and that are simple, such as night and simple rain. You should also have more rain, like rain on tin roof and rain in forest, etc.
