2N BacK
Adaptive dual N-Back training
Free · Designed for iPad. Not verified for macOS.
A faithful dual n-back: the Jaeggi staircase, d-prime scoring, and lure tracking. An on-device coach plans each next session. No account, nothing uploaded.
Dual n-back is a working-memory exercise. A square lights up somewhere on a grid while a letter is read aloud, and you flag it whenever the current square or the current letter matches the one from n steps back. At 2-back that means holding two separate streams in mind and checking each against something two trials old, while new items keep arriving every three seconds.
It is hard, and it stays hard, because the level moves with you.
