Study sprints
Twenty-five minutes on, five off. The tab title changes, so the break announces itself from whatever you're reading.
Time apps
An online countdown timer that tells you when it's done.
Set hours, minutes and seconds, press Start, and go back to what you were doing. At zero it chimes, the display flashes red and the tab renames itself — so it reaches you whether you're watching, in another tab or working with the sound off.

Chime, red flash, tab title
Pause and resume as often as you like, and Reset puts the clock back without reloading the page. What it won't do is survive the tab closing: there's no saved state to restore, which is the honest trade for a timer that never sends your countdown anywhere.
What a plan gets you
Every tool on AppsCyborg sits behind one plan, this one included. There's no free tier and there never has been — the entry price is €1 for a day.
No ads beside the clock
Free timer sites pay for themselves with ads next to the number you're trying to read, and some of them move. This page has none.
The countdown stays in your tab
Once the page has loaded, the timer makes no further request. There's nothing about your countdown for us or anyone else to record.
It reads the clock, not the ticks
The time left is recomputed from your system clock on every update, so a busy or backgrounded tab makes the number jump to the right value instead of quietly drifting behind.
79 tools, one account
The same plan covers every tool on the site — video, audio, images, PDF and ebooks — not just this page.

The row we lose is the one worth reading first: close the tab and the countdown is gone, which a kitchen timer would never do. If you need something that survives walking away from the computer, use the timer on your phone. What this is good at is sitting on the same screen as the work — no install, no ads, and nothing about the countdown leaving the machine.
What people time with it
Nothing exotic. It's a countdown in a browser tab, which turns out to be where a lot of time already gets spent.

ways it tells you
€1
for a 24-hour pass
Cooking and baking
Hands covered in flour and the phone in another room, while the laptop is already open on the recipe.
Workouts and intervals
Set the round, press Start, and let the chime tell you to move without having to look at anything.
Meetings and stand-ups
Fifteen minutes, on the shared screen everyone in the call is already looking at.
Exams and timed practice
One clock in front of a whole room. The red flash lands even with the sound turned off.
Talks and presentations
Keep it on a second screen. It's a number and two buttons, so there's nothing on it to distract anyone.
Whatever you're timing, it runs in the tab and nothing is uploaded.
The rest of the account
This is the only clock on the site, but the plan behind it is the same one that runs Video Cyborg, MP3 Cyborg and PDF Cyborg — 79 tools on one account.
See it run
Twenty-two seconds, recorded on this page. Set the time, press Start, and watch what happens when it reaches zero.
The recording has no sound, and a screen capture has no browser tabs in it, so the chime and the tab title aren't in the video. Both happen.
Create an account and pick a plan to run it yourself.
Questions
Getting started
What is Timer Cyborg?
A countdown timer that runs in a browser tab. You set hours, minutes and seconds, press Start, and it counts down to zero and alerts you. There is nothing to install and nothing to upload — the countdown is a number in your own browser.
How do I know when time is up?
Three ways at once: a short three-note chime, the countdown flashing red, and the tab title changing to "Time is up". The flash and the title keep going for a minute and then stop on their own. Three, rather than one, because a muted tab, a silenced laptop and a deaf user all need the alert to arrive.
The countdown finished but I heard nothing
Sound is created when you press Start, because browsers refuse to play audio that no click asked for. If you restored the tab from a previous session, or the browser reloaded the page in the background, that click never happened and there is no sound to play — press Start again and it comes back. Check the tab isn't muted too: browsers mute individual tabs and remember it. The red flash and the tab title fire either way.
Does it work on my phone?
Yes. It's a web page, so any current browser on Android, iPhone, iPad, Windows, macOS or Linux will run it. On a phone, keep the tab in the foreground: mobile browsers suspend background tabs aggressively, and a suspended tab cannot chime at you.
Using it
Does it keep time if I switch tabs?
Yes. The time left is recomputed from your system clock on every update rather than counted down tick by tick, so a background tab makes the display jump to the right value when you come back instead of drifting behind. The alert can be a few seconds late in a tab that has been hidden for a long while, because browsers slow background timers down — but it fires.
What if I close the tab or reload the page?
The countdown ends. Nothing is stored on your machine or ours, so there is nothing to restore — you'd set it again. That's the trade for a timer that never sends your countdown anywhere. If you need one that survives closing the browser, use the timer on your phone.
Can I set more than 24 hours?
Yes. Put 100 in the hours box and it counts down four days and four hours, showing the days alongside the clock. Below a day the display stays as hours, minutes and seconds. Bear in mind the tab has to stay open the whole time.
Can I run several timers at once?
One per tab. Open this page in a second tab and you get a second, entirely independent countdown — each one alerts on its own and renames its own tab, which is how you tell them apart.
Plan and privacy
What does it cost?
€1 for 24 hours, €6 for a year, or €30 once for lifetime access. Any of them unlocks all 79 tools, not just this one. There's no free tier — creating an account costs nothing, but running a tool needs a plan.
Does my countdown leave my browser?
No. Once this page has loaded, the timer makes no further request: the hours, minutes and seconds you type never reach a server, so there's nothing about your countdown to store. The site itself does record ordinary web analytics — which pages get visited, which tools get used — as our privacy policy sets out. The distinction is real and worth stating plainly: the page is measured, the countdown is not.
Does it work offline?
The countdown does, once the page is open — it needs no network to run. Loading the page in the first place needs a connection, and so does signing in, so this isn't something you can rely on from a plane with the tab closed.
The buttons do nothing
Almost always JavaScript: an extension or a strict privacy setting blocking scripts on the page leaves the buttons inert. Allow scripts for appscyborg.com and reload. If it still won't run, write to us — the address is at the bottom of this section — and say which browser and extensions you're using.
Still stuck?
Write to us and a human answers, usually the same day.
