Brilliant design for traditionally boring brain exercises


Double Dynamo is a version of the "dual N-back" task, a memory challenge that, if repeated regularly at a person's absolute maximum ability, can increase working memory and, in some studies, general fluid intelligence. N-back is popular among "brain hackers" for that reason.

N-back is also, typically, extremely boring, and the wall between "can" and "can't" is very high, and stressful to reach. Dual Dynamo has solved this. Attention to presentation, and easing the player into the task by varying complexity along the way to greater challenges, makes this much more approachable for the same benefit.

The one to get


It's hard to describe just how good this app really is. From the graphics to the mind-bending difficulty, to the gameplay and the music, it's all just top-notch. There really is nothing else quite like it in the brain training, working memory, or n-back space. I've tried them all, and this is the best by far. The best thing about it is that it's challenging and fun - few other apps in this category are.

My one disappointment is that the app doesn't allow family sharing. Otherwise, it's great.


Somethin's Fishy

I don't review apps very often. It takes a truly special app for me to be prompted to rate it. This app is truly amazing, and I think it really does help your brain!
