5 stars: So far the best Nback I've found. It's evolved and gotten better. I would still like a more accurate metric for tracking scores. For example, the ability to look back on average percentage scores for each level to see how they improve before you reach a new level.
5 stars: Does what it's supposed to do. Would be nice to be able to control prgression, maybe succeeding at a level a few times before going to the next. Too many fluke wins...
4 stars: Tough workout. My brain hurts! Thank you for this simple, easy to use application of dual n-back!
5 stars: I don't doing play exactly.because is not explain about the game.but I belive this game is for chalenging the brain.
3 stars: game is great but the sound is to low so I have to increase it and then the advertisement becomes too loud
3 stars: Doesn't appear to follow the rules as described in the tutorial. The level decreases after only 1 session below 50%. It went from level 4 back to level 2 after 1 session at 50%.
4 stars: It's challenging and fun. The best way to increase my iq.
5 stars: Overall it works well but sometimes the sound is skipped and I have to restart it. I hope this bug is fixed soon. Edit: bug is fixed. App is great now.
4 stars: Game sound too low followed by very load advertising.
