About
66 is a visible countdown from 66 to 0 for the activities you want to turn into a habit: a daily workout, a breathing practice, a focus routine, anything you'd rather repeat than track. HOW IT WORKS Pick an activity, and 66 counts the days for you. Each day it's expected, you start it with one tap. Missing a day doesn't reset your progress in Standard mode 66 just keeps an honest score. Hardcore mode is stricter: a missed required activity ends that attempt and starts a fresh one, while your history stays exactly as it happened. BUILT FOR REAL ROUTINES, NOT JUST TIMERS An activity can be as simple as a duration, or built from a sequence of phases effort and rest, focus and break, inhale and hold repeated as many times as you like. 66 speaks each phase as it begins, so you can keep your eyes closed or your phone in your pocket. RUN MORE THAN ONE AT A TIME Track several 66-day challenges side by side a morning routine and an evening one, say each with its own countdown, history, and statistics, never interfering with each other. ON YOUR WRIST TOO The optional Apple Watch companion shows today's activities, starts and stops them, and rings or taps you at the right moment without ever requiring your phone to be nearby to keep going. YOUR DATA STAYS YOURS 66 has no account, no sign-in, and no server. Every challenge, every session, every statistic lives on your device. There is no tracking, no analytics, nothing sent anywhere. It works the same with no internet connection at all. 66 is not a biological rule or a productivity gimmick it's a simple, honest way to watch a number count down while you do the work.Read more

Run several free sessions at the same time, one per Activity: a 12-hour fast keeps going while you work out or read. Home lists each running session with its phase and countdown, below the day's challenge. Finish each one on its own. On Apple Watch, every running session is listed: start another Activity while one is in progress, and end each one separately.
