Joker Chaos Timer

You don't control the clock. He does. Joker Chaos Timer is the anti-Pomodoro. Instead of rigid 25-minute blocks, you set a range ā say, 15 to 45 minutes ā and then you let go. The Joker decides when your session ends. Could be soon. Could be a while. You won't know until it happens. That's the point. WHY CHAOS WORKS Traditional timers create a false comfort. You glance at the clock, see 18 minutes left, and your brain checks out early. With Joker Chaos Timer, there's nothing to glance at. No countdown. No progress bar. Just you, your work, and the lurking knowledge that it could end any second ā or not. Psychologists call this variable interval reinforcement. Slot machines use it. Now your focus sessions do too. HOW IT WORKS 1. Set your minimum and maximum session length 2. Hit start ā the Joker picks a random end time within your range 3. Work. Forget the clock. Stay present. 4. When the Joker is done with you, he'll let you know. That's it. No phases, no stages, no system to learn. FEATURES ā Anti-Pomodoro variable timer with custom min/max range ā Joker animation that triggers at session end (surprise guaranteed) ā No visible countdown ā pure focus mode ā Session log so you can see how long you actually worked ā Notification support for background sessions ā No account. No subscription. No ads. ā Fully offline WHO IS THIS FOR? ā People who game their own timers ("just 3 more minutes") ā Anyone bored of the Pomodoro routine ā Creative workers who lose track of time anyway ā People who find chaos... motivating The Joker doesn't follow your productivity framework. He has his own. Start a session. See what happens.
