App Description
Every morning, you commit real money to 3 things you must do today.
Every midnight, BATSU checks.
Done? Your money stays. Broke your pact? Your batsu is forfeited.
HOW IT WORKS
1. Set your batsu
$5 to $100. You choose the amount at risk.
2. Face the mirror
Look yourself in the eye. Declare your tasks. Lock it in.
3. Complete by midnight
Break your pact, forfeit your batsu.
THE SCIENCE
Your brain feels the pain of losing $50 exactly 2.5x more than the pleasure of gaining $50 (Kahneman & Tversky, Prospect Theory). Loss aversion drives real behavior change. BATSU turns that science into a daily accountability system.
WHO THIS IS FOR
- Founders and operators who measure life in output
- People who know willpower is unreliable
- Anyone ready for real accountability, not gamification
Set up your accountability pact at batsu.io. The app tracks your daily progress and enforces your commitment.
