21Days is a simple and focused habit tracker built around the principle that it takes 21 days of consistency to form a lasting habit.

Create your habit, track your daily progress, and keep your streak alive. The challenge is clear: if you miss a day before completing 21 days, your streak resets and you must start again. Once you complete 21 days, your habit becomes established, and occasional misses no longer reset your streak. This unique approach keeps you accountable, motivated, and fully committed to your personal growth — helping you turn new routines into stable, lasting habits.

Whether you want to exercise, meditate, read, or simply build healthier routines, 21Days makes the process simple, motivating, and effective.

Key Features:

Create and track your personal habits.

21-day streak system to boost accountability.

Clean, distraction-free design.

Take the challenge, stay consistent, and transform your habits — 21 days at a time.
