Don't Break The Chain

Commit to a habit for 49 days (7 weeks). Each day you succeed, draw an X. The visual chain of X's creates powerful motivation—once you build a streak, you won't want to break it.

Features

  • Visual Progress: See your entire year in a beautiful continuous grid.
  • Native Experience: Seamless iCloud sync across iPhone & iPad.
  • Smart Notifications: Context-aware reminders and recovery prompts.
  • Widgets: Track progress from your home screen.

The Science

Visual Progress: Seeing a chain of X's activates your brain's reward system.
Loss Aversion: Breaking a streak feels like losing something valuable.

After 49 days, your new behavior becomes automatic. That's the X Effect.
