I'm a sucker for a delay effect so may well have purchased the LL iOS blind. As it was I didn't need to because it's free to D/L, only requiring an in app purchase to unlock the full feature set.
It took me (at most) a few minutes to appreciate what a heavyweight app this is. Far from a transparent plate reverb and delay, this has bags of character which colours the sound beautifully. Don't bother taking my word for it, though - I'd urge you to try it for yourself.
