Pros and cons of Stockfish Chess app for iPhone and iPad

Stockfish Chess app good for

Very good chess game . But can we have an update to fit the os 4 ? Cause it bugs and stop all the time
Stockfish is the best chess engine out there, obviously the app is really good to, though some bugs exist (mainly while trying to make both sides play by the computer)
This is the best app of chess I have ever seem. Just amazing. Tnx Tord. Just wanted classical annotation like e2-e4.
Very strong engine but it crashes since last update! Please fix it as soon as possible!!!
Thank you very much for this awesome chess software. I think no GM can win against it!
Finally, finally, finally... Free and perfect chess game. Get it before too late.

Some bad moments

Theres this huge bug, it happens if you move to an area that the computer wont have a choice and will have to sacrifice a piece and the computer just wont move at all
Good interface and excellent features but Their is a bug, after a couple of take backs it looses track of its piece and crashes. I would love to get an update (with bug fixes).
Humnhnnn.. Why cant I beat this thing!? Im usually very good at chess, or so Ive been told.
Whenever I use this app my battery dies really fast and my phone gets burning hot. Uninstalled it for a different one that didnt kill my battery
Ok, but crashes a lot - including halfway through a game I was actually winning! Not optimized for iPhone5 and support didnt reply when I emailed them. A shame, because it could be excellent. Im going to get Shredder Chess.
Its a great program for functionalities, but it continuosly crash after 2.0 upgrade...loosing the current game!
