## What is TwentyOne?

TwentyOne is a calm, no-frills habit tracker built around one idea: small steps done daily beat perfect plans.

Pick one routine. Check it in a single tap. Watch your streak grow, day by day. No badges, no XP, no shame — just a quiet record of you showing up.

KEY FEATURES
• One-tap daily check — done, missed, or skip
• Three modes — 21-day challenge, flexible streaks, or infinite routines
• Skip days that don't break your streak
• Undo any day with a single tap
• Edit past days when life gets in the way
• Try Again — restart any habit with one tap when it ends or breaks
• Push the target — extend 21 days to 30, 60, 90, and beyond
• Archive view — a frozen snapshot of every finished or broken challenge
• Today widget for your home screen and lock screen
• One calm daily summary — not a separate ping for every habit
• Hide habit names on the lock screen for privacy
• A clean grid that shows every day at a glance
• Local-first — your data lives on your device, no account required
• Light and dark mode, Dynamic Type, full VoiceOver support

WHY USERS LOVE TWENTYONE
TwentyOne stays out of your way. There is one habit at the center, one tap to mark the day, and a clean grid that quietly fills in. Built for people who would rather close the app and live their day than stare at charts.

— TIPS —
TwentyOne is free with no subscriptions and no premium tier. If the app helped you, you can leave the developer a small one-time tip — a cup of coffee — directly inside the app. Tips are entirely optional.

— PRIVACY —
Your habits are stored locally on your device. No accounts, no analytics, no data sold.
