I have a few friends who run small businesses and they were still calculating employee time cards by hand or with messy spreadsheets. I wanted to build a simple tool for them that was fast, private, and didn't require yet another subscription or account.

EZTimeCard.com is the result. It's a completely free time card calculator that runs entirely in the browser.

All data is saved to local storage, so you don't lose your entries when you close the tab.

It handles daily and weekly overtime calculations and time rounding (15-minute, nearest, etc.).

There's no backend and no server. Your data stays with you.

It's built with Next.js and Tailwind CSS.

I'm looking for feedback on its usability, features, and any bugs you might find. Does it solve the problem well? What's missing?

Thanks for checking it out.
