Cooldown timer
For anything on a cycle: credits that renew every twelve hours, a game timer, a recurring check. Run several at once and they keep counting while you use the rest of the site.
No cooldowns yet
Add one above. It keeps counting while you use the rest of the site, and picks up where it left off if you reload.
What is a cooldown timer?
A timer that restarts itself. An ordinary countdown ends and stops; a cooldown ends, tells you, and immediately begins the next cycle. That is the right shape for anything that regenerates on a schedule — API credits that top up every twelve hours, a daily reset, energy in a game, a machine you can run again after four hours.
The thing that makes it useful rather than annoying is that it counts from the deadline rather than from when you noticed. Check a twelve-hour cooldown fourteen hours late and it is already two hours into the next cycle, exactly as it would be in reality, instead of quietly resetting to twelve and drifting later every single time.
Why do these keep running when other timers do not?
Most browser timers, including the ones elsewhere on this site until recently, live inside the page you started them on. Navigate away and the countdown is destroyed with the page, usually without warning. Cooldowns are held above the router instead, which is why the dock at the bottom of the screen follows you around the site and why closing this page does not stop them.
Each one is stored as the timestamp it will fire at rather than a number being decremented, so a reload, a sleeping laptop or a throttled background tab cannot make it late. What no web page can do is survive the tab being closed, which is the one honest limitation worth planning around.
Good things to track
Subscription credits and rate-limit windows, since knowing you are eleven hours from a reset changes what you do next. Game timers, which is where the word comes from. Anything on a medical or care schedule where the interval matters more than the clock time. And laundry, which is the most-forgotten cycle in any house.
If what you want is a single countdown rather than a repeating one, the countdown timer is the simpler tool, and it can now be handed to the dock too.
Frequently asked questions
- Do the timers keep running if I go to another page?
- Yes. Cooldowns live above the page rather than inside it, so moving to another tool on the site does not touch them, and a small dock at the bottom keeps showing what is running. They also survive a reload, because each one stores the moment it fires rather than a count of seconds ticking down.
- Will it alert me if I close the tab?
- No, and nothing running in a web page can. Closing the tab ends everything; there is no server here holding your timers. Leave the tab open — pinning it is the usual trick — and the chime fires on schedule. For something you genuinely cannot miss, a phone alarm is the honest recommendation.
- What happens if I am away when one fires?
- It rolls straight into the next cycle and marks itself ready, so a twelve-hour cooldown checked fourteen hours later has already started the next twelve rather than sitting there waiting for you. The cycle counts from the original deadline, not from when you noticed, so it does not drift later every time.
- How many can I run at once?
- Three on the free tier, which covers most people tracking a couple of things. Pro removes the cap.
