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.

Verdict

The call

The clearest difference is review sentiment: 123 at 75% against MindSpan Memory Booster's 0%. 123 also leads on ratings volume (1.4K vs 2) and iOS requirement (9.0 vs 15.6). MindSpan Memory Booster's advantage is update cadence (fortnightly vs every 2 months) and rating (5.0 vs 4.8). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
