Small tools that do one job well.

About Benchlet
A one-person studio in Seoul, building for the trades the big apps forgot.
Farriers, home coffee roasters, mobile notaries, lash artists, short-haul truckers, colorists, planted-tank keepers. Each of them has a job that comes up every week and a tool for it that is either a paper form, a spreadsheet someone emailed around, or a subscription built for a company ten times their size. Benchlet builds the small tool in between: one job, done properly, at a price that makes sense for one person.
- 01
One job per tool
A roasting log logs roasts. A lye calculator calculates lye. There is no dashboard to learn, no onboarding tour, and no feature you did not come for.
- 02
No ads, ever
Nothing here is paid for by showing you banners. Where a tool is free, it is free because it costs almost nothing to run. Where it is not, the price is on the page.
- 03
Your data stays yours
Most of our apps make no network requests at all and need no account. Browser tools do their work on your computer, so the file you drop in never leaves it.
- 04
Where you already are
Some jobs belong on a phone, some in a browser, some on paper. Every product page has four buttons, App Store, Google Play, Etsy, and browser, so you pick the one you use.
