BlindSec vs Stop Timer Button Challenge

Stop the stopwatch at exactly 7.00 seconds. Without looking at the clock. That is all of BlindSec. Tap to start, tap to stop — and only then do you find out how far off you were. It sounds trivial until you try it at a table full of people. FOUR GAMES The timing game and Reaction each come in a solo version and a pass-the-phone version for the whole table. • Timing game — stop the clock on the second you were given. With friends nobody sees a score until everyone has finished, and then the results unfold from last place to first. • Reaction — hit the screen when it changes colour. We count the milliseconds. On your own, or in turns with a ranking at the end. • Delayed drawing — you see your own hand from a moment ago. Now try to draw anything at all. • Training — timed challenges. TRAINING Two timed challenges, each at four difficulty levels: Easy, Medium, Hard and Survival — all four free. Before a round you see the range you have to hit. Both ends of it count. • Sudden death — twenty rounds climbing to twenty seconds. Then the target stops growing and starts breaking apart: a round becomes one, two or three stretches timed in a single go, in eight named shapes. • Arithmetic — the target is the result of a sum shown for a moment only. The measurement starts by itself when the sum disappears, so you do the arithmetic while it runs. Every level has its own rule. On Easy it takes three failed rounds to end the attempt. On Hard the average of your last four counts — one mistake passes, two do not. On Survival the first value outside the range ends it. The margin grows with the target, but slower than the target itself — just as human error does. The same level therefore means the same thing in every round. IT CANNOT BE CHEATED The game protects the measurement in several places at once: • The system clock hides for the length of a round. • The background moves in frequencies that cannot be counted — there is nothing to tally instead of seconds. • While measuring there are no sounds and no haptic pulses — individual taps could be counted. Timing starts the moment the system registers your touch, not when the app reacts: tens of milliseconds, enormous in a game like this. RESULTS TO THE HUNDREDTH Times are shown to two decimal places, never deeper: below a hundredth the screen noticing your touch decides, not skill you can train. Equal times are a tie. The two highest grades come from the screen too: one for a hundredth off, one for dead on. STATISTICS AND LEADERBOARDS Round history, records and form charts — free, with nothing trimmed from the past. Separate tabs for the timing game, reaction and training, each in its own unit. The Training map shows how far you have come: eight fields of three stars each, and a hint where the next one is closest. Twelve badges in three tiers, all free. The extended boards are free too: consistency, warm-up, form by time of day, time distributions and an activity calendar. Game Center leaderboards are optional. TWELVE LANGUAGES English, Polish, German, Spanish, French, Italian, Portuguese, Dutch, Czech, Slovak, Norwegian and Turkish. EVERYTHING STAYS ON YOUR PHONE No accounts, no sign-in, no syncing.

A big red button and a stopwatch you cannot see. Tap to start it. Tap again when you believe the target time has passed. The clock stays hidden while it runs, so there is nothing to read and nothing to count. Only your own sense of how long a second is. Can you finish all of the missions? Then it tells you exactly how close you were. FIVE WAYS TO PLAY • Classic — pick a target and chase it, or let the app pick one for you • Arcade — round after round on three lives, with the window closing as you go and a streak multiplier that makes the round you are on worth more than the last • Daily run — five targets, the same for everyone, scored out of 100 • Missions — thirty levels that get tighter, longer and less forgiving • Party — pass the phone around, closest to the target takes the round BUILT TO BE FAIR Your time is measured from the moment your finger touches the glass, not from when the app gets around to noticing. Nothing on screen moves while the clock runs. Anything that repeats on a fixed interval is something you could count, and counting would defeat the whole thing. Play to one, two or three decimals. The grading follows your choice. MAKE IT YOURS Eight button designs and eight displays, or build your own: shape, colours, size, labels. Use one of your own photos as the face of the button. Tune the haptics and the sounds to taste, or switch them off. KEEP TRACK Every attempt is logged. Personal bests announce themselves. Statistics show where you land, and whether you tend to stop early or late. NOTHING LEAVES YOUR PHONE No account. No advertising. No analytics. No tracking. The app has no network connection at all, so there is nothing for it to send even if it wanted to.
