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.

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.

Great dual n-back app

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

Useful, but lacking in interface

The core functionality of this app is great. I have only one complaint, and it is the fact that the center square of the grid is taken up by a large number indicating which n-back your are using. The indicator could easily be put somewhere else, so that the center tile could be used for the visual sequence.

The logging is a little clumsy because instead of making a graph for you, it gives you the raw data in tab-delimited form, and there is a large amount of data to sift through. The inclusion of stats on the bottom of the screen really bother me because I see the numbers changing in my peripheral vision while the app is running a test, and I end up looking back and forth to the grid and the stats to see how I'm doing.

My last complaint is about the most recent update. Yes, it's good to see that the author is keeping the app updated, but I really question the utility of ear training in an n-back app. As a musician, I see very little to be gained from trying to memorize tones. More benefit is gained by listening to chords and intervals. There are quite a few exercises included in this app that I see little use for, and would rather see the author spend the effort on improving the interface.

tl;dr - has potential, but effort spent on making new exercises would best be spent improving the interface
