Very Expensive!! Pay per game is a very expensive option for a game that is so simple. I wasn't even able to test it.
Too expensive It's pay per session... Would have been great if it's a one off payment.
DUAL N BACK It will not let me spell anything
The next level evolution of the Dual N-Back app that is demonstrated to have transfer effects to short term memory and essential cognitive tasks outside of software brain training. I've done brain training for 3 years now and this app is significantly more challenging than anything I've tried before. In HighIQPro my best performance was 7-back and I regularilly trained in the 5-back range and sometime higher. Yet right now I'm doing the emotional n-back training mode and I'm finding that I can barely make it to 5-back.
Best n back for real Little bit lagging
Not actually free It's a pay per play game.
