The refill you want
isn't on the shelf.

So make it. Lay out the page on your phone, print it at home at actual size, cut along the marks, punch the holes, and it drops straight into the binder you already use.

A green six-ring binder open to a printed monthly refill

Pick a page, print it, put it in.

Nothing to configure. Whether you pick a ready-made page or build your own, everything from printing onward is the same.

1  Pick a page The template list

Monthly, weekly, grid and dot pages are built in. If the one you want isn't there, build it yourself.

2  Print at actual size Export at actual size or tiled on one sheet

Print at "actual size" and the lines and the holes land exactly where they should. Tile several pages on one A4 or Letter sheet if you like.

3  Cut and clip it in Aligning front and back for double-sided printing

Cut along the trim marks and punch the holes. The ring side is kept clear, so the holes never cut through a line.

Pages that come built in.

Every image here is real output. Line spacing runs from 2.5 mm to 10 mm in 0.5 mm steps.

Also a two-page monthly, horizontal and left-page weeklies, a year at a glance, hourly schedules, habit trackers, isometric grid, columns and more. New pages arrive without waiting for an app update.

The Japanese calendar, already filled in.

Japanese public holidays in color, the imperial era year, and rokuyō — the six-day luck cycle printed in Japanese planners — all come with the dated pages. Substitute holidays and bridge holidays are calculated the way the law defines them.

Rokuyō is computed astronomically from the lunisolar calendar, so it stays correct across years. Weeks can start on Monday or Sunday. Prefer plain English pages? Turn all of this off.

You don't change your binder to suit the app; the page is made to suit the binder. The diagram below is to scale.

turn the paper

Enter a width and height in millimeters to add a size that isn't listed.

The ring side stays clear

No lines are drawn where the rings sit. The margin adjusts in 0.1 mm steps, so it can match the rings you own.

Tuned to your printer

Home printers shrink a page slightly and shift the back side a little. Print one calibration sheet, measure it with a ruler, enter the values once, and every page after that comes out right.

The editor, splitting a page into blocks

Pick one, or build your own.

Split the page across or down. Split a block again. That is the whole technique — and any block can hold a grid, lines, a table, text, or a monthly or weekly calendar.

  • A calendar placed in a block reflows to fit it
  • Save a combination you like as a part; edit the part once and every copy updates
  • Two-page spreads, and pages that repeat by month or by week
  • A different typeface per block; extra faces download only when you use them
  • Designs and parts export to a file, so they open on another device

Questions

The printout came out the wrong size

Choose "actual size" (100%) in the print dialog. "Fit to page" shrinks the sheet and the holes no longer line up. If a millimeter or so is still off after that, print the calibration sheet, measure it, and enter the values under Calibration.

The back side is out of line when I print double-sided

First check that the binding option is set to "long edge". Then print the calibration sheet double-sided, measure how far the front and back crosshairs are apart, and enter that as the back-side offset. Every printer is different, so the app ships with 0.

What is free?

All of it: the editor, every size, PDF export and the double-sided correction. The only purchase is a one-time option to remove the ads, and it changes nothing else. Ads appear only on the list and export screens, never while you edit.

Where are my pages stored?

Only on your device. There is no account and no sign-in, and neither your designs nor your PDFs are sent anywhere. To move to another device, export a design to a file and import it there.

Do I need the Japanese calendar?

No. Pages come in English with plain weekday names, and the holidays, era year and rokuyō are each a switch you can leave off.

The next refill you want, you can make.
