Memory Meadow: WM Training

Memory Meadow is a quiet game for the part of you that holds things. Blooms open in a meadow, then tuck away behind the grass. A moment later, one peeks back out — and you say whether it is the same as before, or changed. That is the whole idea: a brief look, a short hold, and a simple answer. It is drawn from a real memory-science task called change detection, the same paradigm labs use to measure visual working-memory capacity. SEVEN WAYS TO PLAY Measured — the main game. A few blooms, then the meadow gently adapts to find how many you can hold at once, and reports it as your capacity score, K. Capacity check — the same task at fixed set sizes of 3, 4 and 6, for a clean, comparable reading. Casual — the whole scene returns and you simply say whether anything changed. Slower, gentler, accuracy only. Firefly Trail — lanterns light up one at a time along a trail; tap them back in order, then in reverse. A classic spatial span task, the Corsi block-tapping test, dressed in fireflies. Echo Hollow — blooms drift past one at a time; tap Match when a bloom repeats the colour from n blooms ago. This is the n-back task, and it trains something different from holding still: updating what you carry as new information arrives. Fern's Lantern — the same hold-and-recall task as Measured, but on some rounds Fern lifts a lantern over the spot she's about to ask about just before the probe — a small, honest look at how a cue changes what memory holds onto. Wind Chimes — a short run of chimes plays, one bloom at a time; echo it back by tapping the blooms in the same order. A memory-span task for the ear, so it plays beautifully with your eyes closed. There is also a Weekly challenge — the same seeded set for everyone that week — a Long Wander that strolls through every game in one flowing session, and Two Keepers, for taking turns with someone else. WHAT YOU GET BACK - A daily goal and a streak, with a freeze so one missed day doesn't erase a month - Your capacity (K), spans, and n-back record, tracked over time - Records and achievements as you go - A shareable summary card, built only from your own numbers - A short, honest research page explaining what each game measures — and what the evidence does and doesn't support BUILT TO BE QUIET No account. No ads. No tracking. No network calls. Nothing leaves your phone, because there is nowhere for it to go — your progress is stored on the device, and the only way to move it is the backup you export yourself, as a file or a block of text. Up to three keepers can share the meadow, each with their own streak, bests and settings. An optional daily reminder (a local notification only — nothing is sent anywhere), a calm soundtrack with moods you unlock as you play, sound effects you can mute, and settings for larger text, reduced motion, and slower timing. A NOTE ON WHAT THIS IS Memory Meadow is a playful working-memory exercise built on real tasks from cognitive psychology — change detection, spatial span, n-back. It is not a validated clinical intervention, a medical device, or a diagnostic tool, and it won't diagnose or treat anything. The evidence is honest, too: practising these games reliably makes you better at them, but the best research does not show that working-memory training reliably improves general intelligence or everyday thinking. Play it for what it is — a genuinely enjoyable way to notice what your mind can hold.
