Good but

Subscription rate is waaaaay too high for an app thats impossible to be scientifically proven. The training sessions (games) are decent but only 3 on the free version which isnt hardly brain exercise. I wouldnt pay for the pro version because the range of the "free" games Ive played doesnt really feel like its doing anything to improve my cognitive abilities.
All in all, worth a try but cant really say there will be any tangible differences in your life if you dont use it.
