Who doesn’t need a good chorus? FAC Chorus is a good choice for iOS as a AUv3 plugin. In version 1.2 this app gets better with a brand new preset manager, automation support, which will be extremely useful.

Finally this version makes the bypass button visible everywhere as apparently it wasn’t always supported by hosts.
FAC Chorus costs $2.99 on the app store now:
