Constraint Clock

Constraint Clock is a focus-session timer built around deliberate limitation rather than plain time-boxing. Choose a creative or behavioral rule, run the countdown, and log a short reflection afterward — a lightweight loop for practicing constraint-driven focus instead of just watching a clock.

Features

• —Library of creative and behavioral constraint rules to run sessions against
• —Countdown timer built specifically for constraint-driven focus sessions
• —Post-session reflection logging to track what each constraint taught you
• —Session history for noticing which constraints actually work for you
