Brain rot test · 2 min

Your brain isn't lazy. It's hijacked.

Find out how deep it went. Thirty-six honest taps, a Rot Index out of 100, and a screen time autopsy of where the hours actually go. No account. Nothing leaves your phone.

Start the test

What the test measures

• How soon after waking you check your phone, and how long the first session runs
• When the scrolling hits hardest: dead moments, bed, weekends, all day
• Whether you can stop mid-session, and how often you have tried to cut down
• Eleven rot markers adapted from smartphone-use research

What you get

A Rot Index from 0 to 100 with a plain-language reading, an attention age estimate, and a projection of how many years the feed takes at your current pace. The Rotless app on Google Play turns the result into a day-by-day rewiring protocol with a Scroll SOS, an AI focus coach, and a live counter of the hours you get back.
