Daymark: Habit & Quit Tracker

Daymark is a habit tracker that also helps you quit. Build good routines with daily check-ins, or start a counter for a habit you want to leave behind and watch the days clean and the money saved add up.

BUILD HABITS
• Create habits with your own schedule: every day, certain weekdays, or a number of times per week
• Check in with one tap and keep your streak visible
• Add notes and set reminders for the habits that matter most

QUIT BAD HABITS
• Start a quit tracker and see your days clean grow
• Enter what the habit used to cost and see the money saved
• Reset honestly if you slip, and keep your history

YEAR HEAT-GRID
See your whole year at a glance in a colorful grid. Dark cells and bright streaks show where you were consistent, so you can spot your best months and the weeks that need attention.

STREAK SHIELD
Life happens. A streak shield protects a streak when you miss a day, so one bad day does not erase weeks of effort.

EDIT ANY PAST DAY
Forgot to check in yesterday? Fix any past day, add a missed check-in or correct a mistake. Your habit history stays accurate.

REMINDERS WITH BATTERY DIAGNOSTICS
Phone battery savers often delay or block notifications. Daymark includes diagnostics that show which settings may affect your reminders, so you can fix them and trust your daily nudge.

FREE BACKUP YOU CONTROL
Export all your data to a JSON file and import it on a new phone at any time. Backup is free, and your data is never locked in.

PRIVATE AND AD-FREE
No ads. Your habits stay on your device, and you do not need an account.

Daymark is a self-tracking tool for personal routines. It is not a medical or treatment service. If you need support with a health condition or addiction, please talk to a qualified professional.

Start today: pick one habit, check in, and let your streak grow.
