About this app
Build a habit for 66 days—and make it stick. 66-Day Habit & Streak Tracker is a focused daily routine builder for people who want clear progress, simple check-ins, and a real finish line. No clutter. No account. Just the habits that matter. START IN SECONDS Choose a starter template or create your own goal. Track up to four active habits, set reminders, and check in with one tap. WHY 66 DAYS? Habit change takes repetition. A 66-day challenge gives every routine a clear beginning, visible momentum, and a finish worth celebrating. STAY CONSISTENT • Daily check-ins and a visual 66-day grid • Current streak, best streak, completion rate, and weekly recap • Flexible Day Ends setting: Midnight or Late Night at 3:00 AM • Reminders for your schedule • Home Screen and Lock Screen widgets • Apple Watch check-ins • Live Activities for at-a-glance progress • Flame Guard protection for an occasional missed day • Pause and archive habits without losing history • Trophies and share cards for milestones BUILT FOR REAL LIFE Use it for fitness, reading, meditation, studying, journaling, hydration, morning routines, or quitting a bad habit. The focused limit helps you commit to fewer goals instead of building an overwhelming dashboard. PRIVATE BY DESIGN Your habit data stays on your device.
