TwentyOne: Habit Tracker
Build streaks, day by day
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
A calm habit tracker built around the 21-day rule. Pick one routine, check it in a single tap, and watch a quiet streak grow.
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.

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.
