About CheckWhenDone

CheckWhenDone exists because new habits stick better on paper. You design a check sheet in the browser, print it on a single A4 page, hang it where you'll see it, and check a box every time you follow through. After roughly 20 checks a habit tends to carry on by itself, which is why the default sheet has 20 boxes.

The tool is free and requires no account. There's nothing to sign up for and nothing to install. A sheet's entire configuration is encoded in its URL, so you can share a sheet with someone by sending a link, or reprint your own next batch with the numbering continued from where you stopped.

CheckWhenDone is built and maintained by OlliDev, an independent software developer. The site is a small, focused product: one configurator, one printable page, no upsells. If you have questions or suggestions, see the contact page.
