Recall IQ

Recall IQ is a clean, focused memory trainer that tests how many digits you can recall under pressure.

Numbers flash on screen, then vanish. Your job: type them back from memory. Each level pushes further more digits, more numbers, or trickier formats until your recall breaks.

SIX MODES

Normal modes
• Single: one number appears, then you type it back.
• Double: two numbers appear one after the other, then you type both together.
• Chain: three short numbers appear in sequence, then you rebuild the full chain.
• Multi: a configurable series of numbers appear in sequence (2–8 segments), then you type them all back in order.

Special modes
• Phone: memorize a full phone number (e.g. 06 78 28 39 30) and type it back.
• Plate: memorize a registration plate (e.g. ER 450 AZ) letters and digits and type it back.

THREE DIFFICULTIES
• Easy: longer reveal times, 4 lives, and shorter starting numbers.
• Normal: balanced settings with 3 lives.
• Hard: shorter reveals, 2 lives, and longer starting numbers.

You can also fine-tune the reveal duration with a manual time adjustment.

TRACK YOUR PROGRESS

A built-in dashboard shows your best scores, longest digit spans, average performance, and a session-by-session chart so you can watch your working memory improve over time. Filter between Normal and Special modes to focus on what matters to you.
