About memtry
A lab notebook for your memory: 20 short tests, honest baselines, and a daily challenge shared by everyone on Earth.
What this is
Memtry collects the classic memory paradigms, digit span, the chimp test, Stroop, n-back and 16 more, into clean two-minute games you can run on any phone. Every game page explains what the test measures and cites where the science comes from. No account, no paywall, no dark patterns; streaks even include rest-day grace.
What it is not
It is not a brain-boosting miracle. The research on training transfer is mixed and we say so plainly in our guide. What you get is real: measurable improvement on real cognitive tests, and a daily habit that treats your attention with respect.
