## What is 66?

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.
