Streak21

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. Terms of Use（EULA）: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
