Description from extension meta

Countdown & countup timer, with simple interface and ability to run multiple timers.

Image from store countDown
Description from store QUICK START: I'm working on an improved input system, but for now a quick start for how to use the current one: You can use the mouse scroll wheel, just point to the right time field and scroll the wheel up/down to adjust the value (ddd hh:mm:ss). You can also use the keyboard by directly typing the desired time. First click on one of the timers (anywhere beside notes) and input your time. Examples: To set 15 minutes: 15. or 1500 (00:15:00) To set 72 hours (3 days): 72.. or 3... (3 00:00:00) To set 3 hours and 45 minutes: 345. or 3.45. (03:45:00) To set 90 seconds (1:30): 90 or 1.30 (00:01:30) Fixes: * Fixed keyboard input not registering Features: * Tricky input (still working on it) * (new ) TTS for notes * (new) Shortcuts on badge timer * (new) Options to set different sound alarms and volume * (new) Notification alert (optional) * (new) Multiple colour themes * Multiple timers * High range of spans with up to several years * Count up like stopwatch (to start, set the timer from 00:00:00) * Optimised for extensive use * Display timer one the icon badge * Set and navigate the timers with keyboard * Set timer with scroll wheel * Custom notes for each countdown P.S. Rate the extension and spread the word to encourage the developer (me) to dedicate more time in implementing more features.

  • (2023-01-24) Sadman Hossain: I absolutely LOVE this extension but recently keyboard input has stopped working, which is a massive deal breaker for me. However, I know that the dev is actively working to fix the issue (I can confirm that version 4.1.2 does NOT fix keyboard input; the only way to change timer values remains to be scrolling), and for that I have to give this 5 stars, because I know that they listen to their users and I trust that they will be able to fix the issue and continue to support this extension for years to come. Consistent extension support is difficult to come by, even amongst many popular extensions (that have often had their last update years ago), so this gesture of solidarity means a lot to me.
  • (2023-01-23) Виктор Азаров: Отличное расширение! Супер-полезное и очень удобное. Awesome extension. Very useful! [Bug?] Can't input time using number keys anymore for some reason ( [Suggestion] Would be nice if it would be possible to move timers around (up and down in the list).[Suggestion] Would be great if it would be possible to export and import timers list (for backups and to transfer between browsers/user profiles/computers) [Suggestion] Also would be nice if mouse wheel scrolling wouldn't change timer's time unless editing mode is active on it.
  • (2023-01-19) Roger Valle: Would be 5 stars but the keyboard input doesn't work. :/
  • (2023-01-18) eksine: You cannot input time using keyboard?? what happened to this app? it used to be good, now it's horrible !!!
  • (2023-01-16) universe: best countdown extension but fix input desired time by keyboard please .
  • (2023-01-15) Monique Guebou: Doesn't work anymore with the last chrome update on MACOS
  • (2023-01-13) Adam Balint: This is not a countdown but a countUP app. Also, I have no idea what the icons mean apart from the deletion. There are 3 icons that represent sound.
  • (2022-12-20) matt: scrolling the mouse wheel to set the timer jumps from 5min to 6min30 to 7min30 etc...why not 1,2,3,4,5 ? Garbage app that can't even perform the most simple task correctly
  • (2022-12-11) Zun De: Just what I am looking for. Simple and useful. Thank you very much Alexander.
  • (2022-11-24) Uresia: Very useful thank you, sir
  • (2022-11-23) Arrow Oskar: too cool and simple
  • (2022-11-15) lendon pedregosa: can use a shortcut to directly start the countdown. but overall it is simple, easy to use and very flexible
  • (2022-11-02) Miroslaw Biegun: Great in it's simplicity :)
  • (2022-10-14) João Amadi: This is exactly what I needed. Simple and very effective. Allows for multiple timers and chronometers, I use the notes to name each one and time different activities and automations that I run daily. I needed something easy and accessible to help me track these automations in particular, and this extension was the perfect one for it. Only thing is that it took me a while to figure out where to add the notes to each counter (it's on the little strip on the bottom of each one). One suggestion would be to add a little "add note here" so other people can find it more easily. That's all, because I love it!
  • (2022-10-14) Dr.: Keyboard no longer works for setting the timer, and using the scrollwheel is highly inaccurate. (using slimjet browser)
  • (2022-10-06) imbolc: Blissful simplicity
  • (2022-09-25) Armin Mueller: Worth 5 stars. Simple and effective :)
  • (2022-09-22) Pankaj Dhungana: I was exactly searching for this, I tested 3 and this is it simple and handy.

  • (2022-07-25) cOnfidential cOrp: If you want to edit the timer , click on the timer and press the numbers on your keyboard , and backspace to make it zero
  • (2022-07-19) Дмитрий: Очень хороший таймер! Практически то, что искал: несколько таймеров одновременно, имеют названия и несколько звуков! Главное - очень удобно, использую для браузерной игры! Спасибо! Только непонятно для чего встраивается в атозагрузку...
  • (2022-05-18) tyler corelitz: Ability to have multiple concurrently running timers is great. Would be nice to be able to add time to a running timer that is counting up, either by typing it into the counter after it starts from O or with a +1 minute or +5 minute button. Using this as a supplement to our billing tool which doesn't have a good timing utility for multiple concurrent running timers.
  • (2022-05-12) Arnav Chaudhary: Whoever made this is a genius, with all the small details and features, this has got to be the most handy times I've ever used, but at the same time it was very frustrating to try and understand how it worked when I first downloaded it. If the creator is reading this, please make it more intuitive or explain each feature slightly better in the overview. The complexity overshadows its brilliance
  • (2022-03-23) Антон Игнатенко: Наконец-то я нашел то, что хотел!) Спасибо! Уже думал, что придётся писать расширение самому)))
  • (2022-03-23) Famgz: Very efficient and minimal
  • (2022-03-09) Zrck_069: -Uzun alarm olmalı, en uzunu 3 saniyede bitiyor. -O konuşma balonu ne işe yarıyor? -Tekerlek sayıları karışık arttırıyor..

  • (2022-01-12) Maria Noor: Simple and easy to use. I was confuse how to set it at the start but after I figured it out it's working seamlessly. I love that it notify and give sound when the times end. Excellent product. Very helpful. Totally Recommend!!!
  • (2022-01-06) Jason Yu: My favourite timer extension from the ones I tested out

  • (2021-11-29) nima barghelame: too cool and simple but u need to fix futures and put a legend on it

Really loved the work.. and when the banners shows saying restart it is awesome.. Really appreciate your work.. Thanks for this beautiful work ❤❤❤
  • (2021-09-21) L J: Is there an chance you could add an auto reset toggle for the clocks? Right now with the auto reset upon completion, It's really hard to track which of the clocks i have used.
  • (2021-08-30) HCA Lewisville: Love this timer would really like to be able to share the timers I use across multiple accounts and share/add others so they can see and use the same timer.
  • (2021-08-27) Shouryan Nikam: Pretty simple and straightforward. Gets the job done for me. Would recommend!
  • (2021-08-23) Bach e-mail: Exellent app, simple, complete, sober, perfect, big thanks
  • (2021-08-21) Gamer Always: Excellent extension for windows 7 only. Come windows 10 and notification doesn't always show or sound. I am not sure if it's windows 10 or the 43" LG display. I know for one the google app doesn't work correctly on the monitor; I suspect it can only support 32" and more would cause programs to somewhat function incorrectly.
  • (2021-07-25) Florian Walther: Very useful
  • (2021-07-18) Dan Pan: I don't know why scrolling is no longer working. Is it because I upgrade my chrome?
  • (2021-07-12) Walter Rodrigues: Gostei muito. Muito fácil de usar. Tive que ler como se programava o tempo mas foi a única dúvida que tive e era óbvio. Erro meu. A extensão é muito útil.
  • (2021-06-23) Carlos Alejandro: Awesome extension! I would love to be able to set the counter to large mode for easy viewing (pin).
  • (2021-06-20) Etheric: A great extension for multiple timers. Good variation of alert sounds and nice themes as well.
  • (2021-05-19) Elaine Nguyen: Could you pretty please add a big, visual notification? That is large? I hear a sound go off when my timer is done, but I would also like a big dialogue box or chrome tab to pop up too.
  • (2021-05-10) josh assing: easy to use, multiple timers, not obnoxious alarms/alerts; nice TTS touch.

  • (2022-02-21, v:4.1.1) Dallin Jones: Always on top
    This is so close to what I'm looking for! Is there a possibility you could add the option for it to always be on top? This is my favorite timer (and I've looked at over a dozen), but my main need for it is so that I can study for school (using full-screen video recordings) and see my timer in the corner (or preferably where I put it) while in full-screen mode of the recordings. This would be my go-to timer if I could get that option!
  • (2022-01-28, v:4.1.1) Seth Gordy: Negative Countdown Functionality

  • (2020-04-30, v:4.0.3) Chris Marabate: Difficult to associate which timer goes with which text reference.
    My main issue with this extension is that it seems backwards to me that the text description goes below the timer. I would like the option to have the text description above the timer instead. I also find it very difficult to because all the timers are the same color with no real divider between each of them except for the text description which I always associate with the wrong timer for the reason I stated above. I think there should be a border added around each timer and its text description to make it easier for me to recognize what text description goes with each timer. While I am at it, I also would like to be able to re-organize them in whichever order I want instead of them being stuck in the order I created them.
  • (2020-04-28, v:4.0.3) Chris Marabate: Would like easier way to differentiate timers that have ended from the ones still running.
    Currently the only way I can tell which of my timers have ended is by looking for the "Stop" icon or by looking at if the time is still ticking or not. I would really like it if the timers that have stopped looked a little different from the rest of them in a way that is more noticeable. Having it change color would work but I also have commented on other peoples suggestion saying that I too would like it if there was a way for us to change the color of each timer individually. So if you implement that option as well, then you might need to do something else to indicate the timers that have ended. Maybe something as simple as adding a border around the timers that have ended in a color that would stand out no matter which color we set for that particular timer. But I'm not picky as long as it is easy to tell at a glance which timers have already ended and which ones are still running. Thanks!
  • (2020-04-28, v:4.0.3) Chris Marabate: One small issue: Scrollbar breaks ability to set time after adding more than 8 timers
    This didn't become an issue until I added more than 8 timers. After I add a 9th timer, a scrollbar gets added which makes it impossible to adjust the time of each timer because using the mouse wheel scrolls the scrollbar instead of adjusting the time like it is supposed to. Besides that I absolutely love this extension. But I would really like to be able to have more than 8 timers going at once. Do you think you could fix this for me please?
  • (2020-02-05, v:4.0.3) Nickolas Meinerz: Does this feature exist?
    Is there a way that I can get the timer to display on every tab? I can see it only in one tab and it's only a digital countdown. I have ADHD and visual countdown timers are very helpful--particularly when it is in a circle that gets smaller as it counts down. Or is there a way I can maybe "pop out" the timer as a separate window that I can position on some corner of the screen? Thank you so much!

    When the shortcut keys were enabled for this app, it enabled them on a global basis, which blocks the keydown event for the entire computer. In the future, enabling these as "In Chrome" by default would save a lot of heartache trying to debug what was causing keys to stop working on a computer.

  • (2019-10-07, v:4.0.2) Dee DanyFrostt: fatal prob_dropdown timer list won't open
    * I can no longer open Countdown (to show all the current timers) by using the icon, just to the right of the address bar. * Ctrl + Shift + Y no longer works as well. When I try this, the icon by the address bar shows that it is being selected (light grey background shading vs white) but the list of timers does not open/drop down. I have uninstalled/reinstalled it 3 times now and re-added my timers (from a backup in Wordpad). I am able to open the drop down list a few times... and then it just stops working. I can tell the program is still working because the timers that are still running are causing the popup notifications. * I have the latest version of Chrome (Version 77.0.3865.90) * I haven't changed any hardware/settings * I haven't added/removed any software to my computer * I haven't added/removed any extensions to Chrome * I have rebooted my computer and the problem still exists I didn't realize how much I absolutely rely on your simple-to-use program, until it stopped working. I don't see any other program that is remotely comparable. Any suggestions? If not... is there another extension you can recommend? I play an online game and I am using about 15-20 timers to be efficient in the game... LoLz.. without your program... My gameplay is seriously suffering. Hope you can help. :-)
