5 stars: This is a well organized/coordinated app. Managed to get the full app when it was discounted and will say it was worth every cent. I do see improvement, and that was something I was doubtful of. Would recommend if you have the money to spare and if you're looking to improve brain activity. (Bought the lifetime for around 60 CAD, a steal)
3 stars: The app itself is easy to use and laid out well, they entice you in with a good selection to keep you occupied at first, then once you've had a few go's bam.. it's £2 a month for unlimited go's or £70+ to unlock completely. Seems very excessive when you could buy an old Ds and brain training game for less.. If the price becomes more realistic then perhaps 4/5* . But for now, by all means try .. but you'd be a fool to purchase at full price
3 stars: Too many things or games are locked for free trial. Unable to test and see what other game looks like. Even if the game is free, you can only play once, no replay available, that's sad! If there's more game unlocked for free trial with more replays, that would be better.

5 stars: I haven't gotten the pro yet but I love this app! I try to beat my high score everyday all the while improving my focus, memory, coordin...
