The games are very buggy on mobile devices, unless you only want to play on a desktop I do not recommend this. So buggy you won't get through even one 10 minute session without problems. The monthly subscription is deceptively advertised and a pain to cancel. My account said if I did not cancel by this day I would be billed, so I cancelled on exactly that day, and I was still billed!!!!!!!! The cognitive ranking, which is probably why you want to sign up, is wholly worthless. Sure they'll give you a number but no mention out of how many?!? So what's the point? Every other "score" anywhere is like 80% of 100, cognifits "ranking" is like congratulations your #789. Of what??

Used it for 20 minutes and I was hooked. Great way to exercise your brain!

Started with the exercises in iOS 7 and was able to do most on an iphone. I got the subscription through buying the MindWorks supplement. The Mahjong puzzles are easier on an ipad though. In iOS 8 all the exercises that require hand eye coordination don't work anymore. Also, in Mahjong I seem to be perpetually stuck at level 5.4 even though I've completed it successfully numerous times. Hope they can fix these bugs soon. Otherwise a very good and really challenging app.

Really enjoyed the variety of games and was hooked from the start! Until I ran into problems with lots of bugs on the mobile version. One game doesn't even work - always a frozen screen. Several other games freeze at certain levels which prevents you from progressing to the next level. Very disappointing and I would not recommend paying for Cognifit.
