What we make

Three kinds of useful

Start with a free tool. When you need the whole job done, there's a template or a kit for it.

Free tool

Our standard

How we make things

One job, done properly

Each product solves one problem from start to finish, rather than a bundle of half-finished tabs.

Numbers you can trust

Formulas are checked by automated tests against an independent model before anything is released.

Yours to keep

Pay once, no subscription. Templates live in your own account, and your data stays with you.

New tools, now and then

Get an email when we add a calculator, a template or a new trade. No more than a couple a month, and you can unsubscribe from any email.

Sign-up runs on our store page, powered by Gumroad.

About

Fresh out of the kiln

Popkiln is a small independent studio making digital products for people who make and sell: calculators, spreadsheets and kits that each do one job well. We start with one trade at a time and build its shelf properly before moving on.

A kiln is where raw clay comes out finished and ready to use. That's the idea behind everything here: small things, made properly, that you can put to work the same day.
