Challenging and fun brain training game
Elevate Brain Training is a fun brain training game with tests of focus, speaking skills, processing speed and more.
You must sign up for an account either via Facebook or email and then configure a program according to which skills you'd like to sharpen such as listening, brevity, focus etc.
The tests are very well thought out and with up to 100 levels, it's tough enough to challenge all ages. My program wasn't exactly as requested but it's one of the better brain training apps out there.
