It's a really nice training app, but the interface is very 'cheerful', causing the user to watch animations of achievements and introductions to the challenges a lot of the time, instead of really working the brain, which is annoying. Free version is heavily ad-supported. I'm not trying the paid version.

i really love this game! i play nearly everyday. the only reason i give four and not five stars: some of the mini-games are designed to teach patience. as such, these games can go a long time without me touching my screen. there's no function of the app, however, that keeps my screen from dimming in these situations. it would be super-helpful if no-screen-dimming could be incorporated into the app as a whole. fix that=5⭐.

I would like a refund. When I signed up the app said they will send us a reminder before payment. I never used the app and never received a reminder. They've gone and charged $90. I know it said it would remind us which is why I started the trial. Very disappointed in your sneaky sales tactics, lulling people into a false sense of security.
