A simple habit tracker built around calm 21-day streaks.
Core features work without an account.
Subscriptions are optional and unlock additional features.
Streak21 is a simple habit tracker built around one idea:
consistency matters more than intensity.
There are no scores, no pressure, and no complicated systems.
Just show up, one day at a time.
Streak21 helps you build habits in calm 21-day cycles.
You track whether you showed up — not how perfectly you performed.
Features:
• Track habits in focused 21-day cycles
• Simple daily yes/no check-ins
• Streak-based progress, no scores
• Clean and minimal interface
• Optional reminders
• Designed for long-term consistency
Streak21 is for people who want less pressure
and more quiet structure in their daily life.
