Ability Tests
Short browser-based ability tests covering attention, working memory, response control and reaction speed. Everything runs locally, with no sign-in.
Ten single tests
Choose by task, not by diagnosis. Single-test and composite boards are ranked separately.
Search & selection
Find a target, filter distractors, or follow the ink color.
Target Tap
Locate a target in a grid and measure the accuracy and speed of visual search.
Standard challenge: 20 roundsTarget accuracy · correct-response timeOwn standard leaderboardVisual Search
Find the distinctive shape among similar ones and measure visual search.
Standard challenge: 20 roundsSearch accuracy · correct-response timeOwn standard leaderboardStroop Test
Measure resistance to interference by choosing the ink color, not the word.
Standard challenge: 60 secondsColor accuracy · interference (when enough samples)Own standard leaderboardSequences & updating
Reproduce positions, compare earlier stimuli, or continue a number pattern.
Memory Grid
Remember a spatial sequence and reproduce it in order to measure short-term spatial memory.
Standard challenge: 15 roundsWhole-sequence accuracy · recall timeOwn standard leaderboardN-Back
Measure working-memory updating with a visual matching task.
Standard challenge: 30 roundsHit rate · false alarms · balanced accuracyOwn standard leaderboardSequence Recall
Find the pattern in a number sequence and continue it to measure sequence reasoning.
Standard challenge: 15 roundsPattern accuracy · response time, not memory spanOwn standard leaderboardRules & response control
Withhold a response, switch rules, or combine two features.
Go / No-Go
Respond to GO signals and hold back when a No-Go signal appears.
Standard challenge: 60 secondsGo hits · No-Go withholding accuracyOwn standard leaderboardRule Switch
Measure attention switching as the matching rule changes.
Standard challenge: 20 roundsOverall accuracy · switch-trial accuracyOwn standard leaderboardDual Focus
Track several visual features at once and measure how well you divide attention.
Standard challenge: 20 roundsOverall accuracy · dual-feature accuracyOwn standard leaderboardReaction Time Test
Click when red turns green. Choose 3–20 rounds with a tutorial warm-up and view your average reaction time.
Standard challenge: 5 roundsFive-round average reaction timeOwn standard leaderboardStandard challenges automatically join a pseudonymous leaderboard without registration or manual submission. Random codes, best scores, key test metrics and dates are public, but account details and raw responses are not. You can generate a seven-day link to share a snapshot of an aggregate result.
Results reflect this test and device conditions. Compare them with your own history, not as a diagnosis.
