There are some already. Look for DAF or "delayed auditory feedback" on the play store. It is also trivial to build one with web audio.

Nope. They absolutely cannot be delayed auditory feedback. That disrupts speech. The device must reproduce the chorus effect. [0]

Some of those DAF apps can also apply pitch shifting (which is actually AAF). Provided they work properly, they should be able to provide that choral effect. I am no expert by the way, I've only toyed with those for a few minutes.
