RotMeter: Brainrot Score

How rotted is your brain today? RotMeter gives it a number.

RotMeter watches how long you spend in TikTok, Instagram, YouTube, X, Threads, Reddit, Snapchat and Facebook, and turns it into a daily Brainrot Score from 0 to 100. Short-video feeds count for more. Cross your budget and the meter goes orange.

The cute app that tells you you’re rotting your brain. Then helps you stop.

🧠 BRAINROT SCORE
• One number for the day, 0 to 100
• Ten-segment meter: teal is fine, orange is HIGH ROT
• Worst offenders ranked by minutes against their own budget
• Streak of days under budget, with your record

⏱️ FOCUS SESSIONS
• 15, 25, 50, 90 or 120 minutes
• Pick the apps to watch; open one and it shows up as a slip
• Strict mode: no quitting early. Well, not easily.
• Zero ads during a running session. Banner and nav slide away. That is the product promise.

🚧 APP LIMITS
• Daily budget for all doom-apps, plus a slider per app
• Nudge when a limit hits, one notification per limit per day
• Savage mode: nudges roast you instead of asking nicely
