Live countdowns
Add the dates that matter. The closest one counts down to the second at the top of the screen; edit or remove any of them whenever you like.
Made by Powerhouse Digital · Free app
Kairos.
A small, fast app that keeps your countdowns, your calendar and today's plans in one place. The next big moment ticks live at the top. No account, nothing to download from an app store, and it keeps working when you're offline.
Everything you're
counting down to.
Month calendar
See the whole month at once, with every day that has something on it marked so nothing sneaks up on you.
Daily plans
Write down what today needs and tick each item off with a tap.
Installs anywhere
Add it to your phone's home screen or your computer's dock or taskbar, and it opens like any other app. No app store.
Private by design
No sign-up and no account. Everything you add is saved in your browser, on your own device, and never sent to us.
Works offline
Once it has loaded, Kairos keeps working without a connection, on a plane or out of signal.
Free
No subscription and no paid tier. A single small ad keeps it free.
Fast + light
Opens instantly, even on older phones, and takes up almost no space.

The name
Why "Kairos"?
The ancient Greeks had two words for time. Chronos was time passing on the clock. Kairos (καιρός) was the right moment, the one worth waiting for. A countdown is a way of watching for your kairos, so that's what we called it.
