Your timers

Run several named timers side by side — pasta, eggs and a call — and they wait for you here, saved on this device only.

Straight to a time

The timers people open most. Every duration from 1 second to 24 hours has its own page, listed below.

New

More than a timer

Countdowns you can share, games to challenge friends, and a room to study together.

Count down to anything, together

Birthdays, weddings, trips, launches: make a live countdown in ten seconds and share the link. The preview shows how many days are left.

10 Second Challenge

Stop the clock at exactly 10.00 — the numbers vanish after three seconds. Then dare your friends to beat you.

Reaction Time Test

Wait for green, then tap as fast as you can. Five rounds give your average in milliseconds, and a link to dare friends.

Chess clock

Blitz, rapid or your own time control, with increment or delay. Tap your side to end your turn, on one phone between you.

Group Pomodoro room

One link, one timer for the whole group. Everyone focuses and takes breaks together, no accounts.

Share your week

Turn this week's focus into a picture for your story or group chat, made entirely on your device.

Quiet on the outside, exact underneath

Keeps true time

Counts against the real clock, so it stays exact through background tabs, sleep and reloads — and the alarm rings until you press Stop. How it is tested.

No ads. No signup.

Nothing to install, nothing to sign. Your timers, sessions and streaks stay on your device.

Calm by design

Scenes stay still on timer pages unless you ask for motion, and every scene is a still painting with reduced motion.
