## What is RecallBloom?

Train your memory with a brain game you can start in about a minute. Remember positions and spoken letters, compare them with earlier rounds, and see your practice in clear numbers.

RecallBloom makes Dual N-Back training easy to start: tap when the position or sound matches, and wait when it does not.

REMEMBER WHAT YOU SEE AND HEAR
A tile lights up and an English letter plays. Decide whether each matches the one from a set number of rounds ago. As new information arrives, keep the recent positions and sounds in mind.

START WITH A SHORT SET
A standard set has 20 scored rounds, three seconds each, plus the opening rounds you need to remember. Begin with about a minute of practice, pause when you need a break, and resume later.

SEE WHAT CHANGED
Compare your mistakes with your previous or first set at the same level and task. Review position and sound mistakes separately, and follow your results on a graph.

KNOW YOUR NEXT GOAL
Your challenge path shows your current level and what comes next. Look back at the day you started, the levels you cleared, and your latest results.

LEARN BY TRYING
Three short practice questions introduce the rules. Try the matching buttons and learn the timing before starting a full set.

PRACTICE AT YOUR PACE
Use automatic difficulty adjustment or choose a level manually. Adjust the sound volume and switch between light and dark themes.

No account registration is required. Training records are stored on your device.
