Does anyone use the CInema P3 app? Can you give information on the cinema and cinema2 image stabilisation options?

Recently found this app, and was intrigued to find it's extra 2 image stabilisation options beyond the pretty good apple IS - "cinema" and "cinema2".

The IS is very smooth, though there's quite a delay when using it, and there's no documentaion abou them that I could find.

Can you us them in normal day to day recording, or do you find the delay is too much?
