MinuteMemory

Short offline drills for working memory: digit span, spatial grid, and color sequences. Brief display, then recall. No account or ads; best scores stay on your device.

MinuteMemory is a minimal app for short-term memory practice during quick breaks.

Three modes Digits: Memorize a number string, then type it after it hides. Length adjusts roughly between 3 and 8. Spatial: A 3 by 3 grid highlights cells in order; after hiding, tap the same order. Count adjusts roughly between 2 and 8. Colors: Memorize a color sequence, then tap swatches in order. Count adjusts roughly between 3 and 6.

Each round shows the stimulus for about two seconds. A correct round increases the next difficulty; an incorrect one decreases it. In Settings you can toggle sound and haptics and set the starting difficulty for each mode when you reset.

The app works offline, does not require an account, and stores your records on device only. It is for self-practice and leisure, not medical diagnosis; consult a professional for health concerns.
