Show HN: I built a simple, free sit/stand timer to fix my bad desk habits

Hi HN,

Like many of you, I spend long hours at my desk — coding, reading, working. I know I should stand up more often, but I always forget and end up sitting for hours. So I built a tiny web app to help me — and maybe you too.

It’s called StandUpBuddy — a free, browser-based timer that reminds you when to sit and stand. You set your own timing (like 40 minutes sitting, 20 standing), and it gives you gentle, friendly notifications to switch.

Features:

Customizable sit/stand ratio

Start, pause, and reset controls

Runs entirely in the browser

No accounts, no tracking, no ads

100% free

It’s minimal by design — just something that quietly supports healthier habits during long sessions at the computer.

Would love to hear your thoughts, feedback, or ideas for improving it!

But i always stand now and I've never been less healthy!
