App Description
Dual N-back. Scientifically proven memory workout!
- Every session consists of 40 turns. Each turn a square will light up in a 3x3 grid and a letter will be read out loud.
- Your job is to remember both the letter and the position of the square - and then indicate when the current square or letter is the same as it was N turns ago.
- As you get better, the number of turns N you have to remember is increased.
