About CountDownr

Just released: CountDownr on your iPhone and other smartphones. Please check it out:


More news...

CountDownr is my little Ajax project which gives everybody his own collection of countdown counters. Each counter is customized to its own time and date when it goes off. There are two types of counters:

  • Counters for a specific date and time. These counters can be repeated daily, weekly, monthly or yearly which advance automatically when the alert goes off. They are perfect for reminders on single events, lunchbreaks, weekends, paying your monthly bills or birthdays and holidays.
    Example: Midnight
  • Counters which read the upcoming events from public Google Calendars. Any public calendar can be the source for a counter. It advances automatically to the next event after each alert.
    Example: Google Developer Calendar
How is it done?
CountDownr uses Javascript to manage and render the clocks. So everything runs locally on your browser.
Where is the state stored?
CountDownr stores the state completely in a local cookie. There is no personal data stored on our servers. This way the set of clocks is individual for each computer.
In case you want a collection of counters (and many more Apple Dashboard widgets) which state is stored on the server so that it can be access from everywhere please try
Widgetop - Your Web Desktop
What about my private calendars?
Unfortunately Google doesn't support the access to your private calendars the same way as for public calendars at the moment.
If you want to get a counter for your private calendars please try the Calendar Counter on Widgetop.
I like the counters, can I have one on my homepage?
Sure. Go to our Syndication page and create the code for your counter. Copy that code snippet to your homepage and it should work. I would be pleased to hear about it.
Can we promote our events on your site?
CountDownr is a great place to advertise your events and event calendars. Please see our advertising page for the details.
Apple Dashboard Widget?
Yes, actually this project started as a little Dashboard widget. You can download it from here.
If you want to see it running you can test on the Widgetop web desktop.

What about IE?
Countdownr runs on IE but there are limitations because even IE7 still doesn't support the CSS opacity property. With IE6 you won't have any fun because it misses support for transparent PNGs.
If you want to have see the counters perfectly please use a modern browser like Firefox, Safari or Opera.
