Hi Product Hunt, I'm the maker of Bursta.
It's a free interval timer that runs in the browser. Every workout format has its own page, and each page opens on that format's numbers, ready to start: boxing rounds of 3 minutes with a minute of rest, Tabata's 8 × 20/10, the Norwegian 4x4, a 7 minute workout circuit, box breathing, and 15 more.
What it does:
A bell at every change, and a warning before a round ends
A big clock with a fullscreen key, for a phone, a laptop or a gym TV
Keeps the screen awake where the browser allows
Rising and falling tones that pace each breath on the breathing pages
It reads the wall clock every frame and keeps no tick counter, so a stalled tab does not put the count behind. One honest limit: keep the tab in front, because a browser may pause the sound of a tab you cannot see.
Under each timer there's a short article on the format, with the sources behind its numbers.
No install, no sign-up, nothing to pay. Which format is missing?
