## What is DeadBrain?

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.
