Numerical Audio has introduced RF-1, an algorithmic reverb for iOS.

RF-1 is a collection of algorithmic reverbs, capable of creating a variety of effects, ranging from small rooms to huge, heavily modulated spaces. The iOS reverb integrates with everything from AudioUnit Hosts over Audiobus to Inter-App Audio, Guitar- and USB Interfaces.
