⸻
Daily Habit Tracking
Mark habits complete with a single tap. Swipe between weeks to move through your history and revisit any past day to log or update entries. Add a personal note (up to 500 characters) to any completed entry. It works like a lightweight habit journal you can look back on whenever you need it.
⸻
Calendar Views
Switch between a weekly view and a full monthly calendar to see your progress at a glance. The monthly view works as a goal tracker, helping you spot patterns, find gaps, and stay accountable across the whole month.
⸻
Streak Tracker
Your streak counter updates automatically as you log daily habits. Watch consecutive days stack up and use that momentum to keep your routine on track. Streaks are calculated from your actual entry history, not estimates.
⸻
Make It Yours
Customize every habit with an emoji icon, one of 12+ preset colors, or a fully custom color from the color wheel. Your habit tracker should feel personal, because consistency is easier when you actually enjoy opening the app.
⸻
Celebrate Your Wins
Complete all of today’s habits and Check Square rewards you with a confetti burst. Small wins deserve recognition. Positive feedback helps your daily habit tracker feel less like a chore and more like a ritual.
⸻
Dark Mode
Full dark mode, light mode, and system-adaptive theme support so the app looks comfortable in any lighting condition.
⸻
Private by Default
No account required.
No sign-up needed.
Every habit entry, note, and streak is stored locally on your device. Check Square works offline and keeps your data private and under your control.
⸻
Whether you want to drink more water, read every day, exercise consistently, or finally make progress on a habit you’ve been putting off, Check Square gives you a simple, distraction-free habit tracker built around daily habits that actually stick.
A streak tracker and routine tracker in one place. No subscription. No login. No clutter.
Just your habits and your progress.
