Watch. Remember. Answer. MindSpan trains the most important cognitive skill you have: working memory. A shape moves across the screen. You watch. Then you answer: what was it? What color? What pattern? Sounds simple. It isn't. HOW IT WORKS Each round, a geometric shape — triangle, star, polygon, moon — travels along a path. Your job: hold it in mind, then identify it from a set of options. As you improve, shapes move faster, paths grow more complex, and the distractors look more alike. CHALLENGE LEVELS Between the memory rounds, brain-teasers change the pace — mental math, logic and odd-one-out puzzles, lateral-thinking riddles, and number patterns. The question stays on screen; you reason it through. Memory and reasoning, woven together, so no two sessions feel the same. WHAT YOU'RE TRAINING Working memory is the brain's scratchpad — the ability to hold and manipulate information in real time. It underlies reading comprehension, mental arithmetic, decision-making, and sustained focus. Research consistently links working memory capacity to fluid intelligence and learning ability.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
MindSpan Memory Booster holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: 123 has 1.4K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 0% of MindSpan Memory Booster's written reviews are positive against 75% of 123's, so the app with the better star average is not the one people write more warmly about.
MindSpan Memory Booster ships an update fortnightly, 123 every 2 months. The most recent releases landed on November 2, 2026 and November 6, 2026 respectively.
