Recall IQ

How many digits can you hold in your head? ​Push your short​-term memory with escalating number challenges. ​Six modes, three difficulties one sharp mind.

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.

DESIGNED TO RESPECT YOUR TIME • No sign-up required. Just open and play. • All progress is stored locally on your device. • No social features, no leaderboards, no distractions. • A single, non-intrusive banner ad keeps the app free hidden during gameplay.
