Habit tracker & printable generator

Mark habits on a monthly calendar and export a printable tracking grid.

YOUR WORKSPACEProcessed on your device

Choose a month, add up to 12 habits and mark days manually. Changing the month clears marks for review. Completion is marked days divided by all calendar days, including future dates.

Choose a valid tracking month to mark days.

JSON backups are needed to resume later. CSV and PDF are report snapshots. Large reports stop at 40 pages. This PDF uses one landscape page and rejects text that cannot fit.

Nothing is saved automatically. JSON backups are readable, unencrypted files. Export before closing. PDFs support Latin, Greek and Cyrillic text.

How privacy works

How it works

Choose a tracking month, enter habit names and mark calendar days manually. Build a completion report, print the monthly grid and export JSON to keep the editable record.

Supported formats

Up to 12 habits; valid Gregorian months in years 0001–9998. CSV marks, one-page landscape PDF grid and JSON backup.

Good to know

Completion is marked days divided by all days in the month, including future dates. It is not a verified behavior or health measurement. Changing the month clears existing marks for review.

Worked example

Before

Read is marked on four days of a 31-day month

After

A completion figure of 12.90% and four marked cells on the printable grid

The same four marks in a 28-day month would produce a different percentage.

Keep the month and its marks together

The backup includes habit names, selected month and day numbers. Export it before closing. Print the blank grid if you prefer paper; the PDF does not store marks you add with a pen.

Troubleshooting

Why did changing the month clear my checks?

Day numbers belong to a specific month. Clearing them prevents last month’s marks being silently assigned to different dates. Import a saved backup to restore the original record.

Common questions

Does the tracker send reminders or verify completion?

No. You mark days yourself. No notifications, sensors, account history or external tracking are used.

Can I use this without an internet connection?

Yes, after you prepare this tool from Offline help and the browser retains its assets. Installation is optional. All processing dependencies are bundled locally.
