Reflex Lab: Brain Speed Test

How fast is your brain, really? Reflex Lab packs 15 measurements of reaction time, memory, focus and motor precision into one app. A round takes 30 seconds to a minute. And instead of just throwing a number at you, it places that number on the human distribution curve — so you see your percentile and a rank from S+ down to D. ■ 15 tests • Reaction Time — tap the moment the screen turns green • Auditory Reaction — the screen never changes; react to sound alone • Mind Clock — judge a target duration with no clock to help you • Aim Trainer — hit targets fast and accurately • Typing Speed — retype sentences against the clock (WPM) • Number Memory — how many digits can you hold after one glance • Sequence Memory — reproduce the order the tiles lit up in • Visual Memory — remember every tile that flashed • Chimp Test — can you out-remember a chimpanzee • Verbal Memory — have you seen this word already this run • N-Back Memory — a working-memory task: same tile as N steps back • Color Trap — catch the clash between meaning and ink colour (Stroop) • Impulse Control — tap on green, hold back on red (Go/No-Go) • Instant Count — grasp the quantity at a glance, without counting • Peripheral Vision — keep your eyes centred and name the direction ■ Not just a score — an interpretation • Your position on the human distribution curve, with a top-% figure • Ranks from S+ / S / A / B / C down to D • An ability radar across Speed, Memory, Focus and Motor • A combined brain score and its trend over time • A weakness report built from your round-to-round spread • Pick an age band and everything is recalculated against your peers ■ A reason to come back • Daily Challenge — 5 tests chosen by the date, identical for everyone that day • Streaks, and a freeze to rescue one when you miss a day • 30 achievements • Full Gauntlet — every test back to back, then one combined report ■ Built to be comfortable • 10 languages: English, Korean, Japanese, Chinese, Spanish, Portuguese, French, German, Indonesian, Vietnamese • Works offline — no sign-up, no login, no server • Backup export and restore (JSON) • Shareable result cards • Dark and light themes, colour-blind mode, left-handed mode • Personal targets per test • A daily reminder at a time you choose ■ Privacy Your records and settings stay on your device and are never sent to the developer.
