It is one of the more expensive applications out there 14.95 € / 19.50 $...
If you have and use FL Studio-
this would be pretty much a must have as it integrated with the FL Studio for PC,
you can take the saved mobile version and open it up in your Pc version
and things will be synchronized.
My biggest "problems" is that it does not have any kind of tweakable synthesizer
and no way to import your own samples-
you are bound to the sounds they provide for you...
But it is probably pretty incredible for sketching out ideas and even if you dont have FL Studio PC you have midi save and import- so it can be pretty handy...
Plus that it is supposed to work on one of my not so strong devices- HTC Wildfire S.
But will it beat SunVox or Caustic in flexibility and use?
