Im with most on this - the app you did not know you needed
Hate to admit it, but a few weeks ago I found my 55 year old brain struggling with multiplication. I had clearly lost what little edge I might have had. Ive been working with Brain Tuner and while I cant provide scientific data that its improving my mind, It forces me to intensify my focus, which can not be a bad things. Im still on the slowest speed but will drop by again after Ive used for over a month. I like the score and feedback that comes up after each session.
