Monday? Sleepless night? Your brain knows. 75 seconds, 3 games, one merciless number: your brain's battery % TODAY. Send the challenge and watch your friends power down. Your phone shows its battery percent. DeadBrain shows YOURS — how much energy your brain has left today, after that night, after that coffee (or lack of it). 75 seconds. 3 games. Zero mercy: TAP TAP — smash the screen for 7 seconds. We measure power, jitter, and the exact moment you fade. Because you will. BS DETECTOR — true or BS? 3 seconds per statement. Hundreds of questions, autopilot always loses. RAM — repeat the tile sequence. Longer every level, until your memory overflows. At the end you get your BRAIN CHARGE % — from power, vigilance and working memory — plus a meme verdict with a stamp: from "NUCLEAR REACTOR" to "BRICK MODE". Then the best part: send friends a result card with a challenge. Let them prove they've got more percent. They won't. • Your charge changes through the day — measure in the morning, after coffee, after meetings, after the party • Today's readings history — see when you actually drain • Nerd mode: full telemetry of every trial • In English, Polish and Spanish • No accounts, no ads, no data collection It's a game, not a medical diagnosis. You'll still take it personally.
