Improve your fluid intelligence with BetterBrain.

Fluid intelligence is the ability to reason and solve new problems independently of previously acquired knowledge. With BetterBrain you practice challenging memory tasks where you have to remember simultaneously audio and visual events. A scientific study has shown a positive effect of this training on the fluid intelligence of a test group.

The memory task you need to practice is the 2-back task where you must remember the letter you heard two steps back in the past and simultaneously the position of a square on a three by three grid.

BetterBrain features multiple user controlled settings such as two additional training tasks (audio position, color change, form) and adaptive difficulty control: Once you make sufficient progress, you may work on the more challenging 3-back task and if you make too many mistakes, the level will be reduced. Another advantage of BetterBrain is the possibility to practice dual channel memory tasks which are either fully audio or fully visual.

You can also export via email or iTunes a complete log file of your training sessions for later analysis.

Awesome n back trainer

As far as n back options for ios go, this is the best I have found so far. My only complaint so far is it took a while to learn the labels... visual apparently referred to position which was confusing.

Great dual n-back app

Exactly what I was looking for. Works flawlessly. Thanks for making such a useful app!

Good, but...

I like this app, it serves the purpose. However it would be nice if you could export the log in a more friendly format like a graph or excel file instead of tsv.
