How fast are you today?
Eight short tests of reaction, memory, typing and focus. Do one, or do the round and get a single score for the day. Your history stays in this browser — there is no account, no leaderboard, and nothing is uploaded.
Start the daily round All eight, about five minutes, one score.The eight tests
- Reaction Time Test Five rounds, your median, and every attempt you have made.
- Typing Speed Test WPM, accuracy and consistency, letter by letter.
- Number Memory Test One more digit each round, until you drop one.
- Sequence Memory Test Watch the pattern, repeat it back, one longer every time.
- Verbal Memory Test New word or one you have seen? The list keeps growing.
- Visual Memory Test A pattern flashes once. The grid grows every level.
- Aim Trainer Thirty targets, timed, plus the misses most trainers hide.
- Stroop Test Name the colour, not the word. See what the conflict costs.
Why there is no account
Your results never leave this browser
Every test runs entirely on your device and stores its results in local storage. Nothing is transmitted, so there is nothing for us to see, sell or lose. That is also why there is no sign-up: there is no server-side record to attach an account to.
The trade-off, stated plainly
Nothing syncs between devices, and clearing your browsing data deletes your history. There is an export button that produces a JSON file you can import elsewhere — the manual version of sync, and the honest one.
Scored against a fixed scale, not other people
Each test converts to a figure out of 100 against a fixed range rather than a percentile. Your score cannot move because of who else played today, which is what makes a personal history worth keeping.
No streak mechanics designed to trap you
There is a streak, because a reason to come back is the point. There are no notifications, no emails and no way to lose progress by missing a day beyond the streak resetting. Your history is kept regardless.
A note on what these are
These are consumer tests in a web browser, built to be fun and repeatable. Your screen, your mouse and how much sleep you had all move the numbers — so compare yourself against your own history rather than against anyone else, and treat a bad run as a bad run.
None of them is a diagnostic instrument, and a low score is not evidence of anything medical. If you are genuinely worried about your memory or attention, that is a conversation for a doctor rather than a browser game.
