Countdown
Flip clock timer
A flip countdown timer with presets, custom hours and minutes, alarm sound, and shareable links.
Type or use the mouse wheel over a field. Deep link: /timer/?m=25
How the flip countdown timer works
Pick a preset or type your own hours, minutes, and seconds, then press Start. The remaining time folds down on large flip digits, and the browser tab title mirrors the countdown so you can track it from the tab bar. Pause resumes from the exact remaining second, Reset returns to your typed values, and Repeat restarts the same length after each finish.
Presets and direct links
Seven one tap presets cover common sessions from 5 to 60 minutes. For other lengths, type values directly or scroll with the mouse wheel over any field. Every length has a direct link: add ?m=25 to the timer address to open a 25 minute countdown, with values from 1 to 999 supported. Bookmark favorite lengths or send the link to someone else and they start from the same value.
Alarm sound and notification
Choose an alarm tone from the dropdown and set the volume slider. Selecting a tone plays a short preview, and reaching zero plays the full sound with a Time is up message. The browser asks once for notification permission on the first start. Grant it to receive a system note alongside the sound, which helps when the tab sits in the background.
Accurate in background tabs
The timer stores its end moment as a timestamp and recomputes the remainder from your device clock on every update. Switching tabs, minimizing the window, or briefly sleeping the device does not skew the result the way counted ticks would. Keep the volume up and the device awake for the alarm, since muted tabs and full system sleep can suppress sound.
Good uses for a flip timer
Study sessions pair well with a 25 or 50 minute countdown on a second screen, since the large digits show the remaining time without opening another app. Cooks set quick reminders for steeping, resting dough, or oven checks. Trainers run interval blocks with Repeat on, and teachers project the timer during silent reading or group tasks. Because the page needs no account, each use starts in seconds on any shared computer.

FAQ
How do I set a flip clock timer?
Pick a preset such as 5, 10, or 25 minutes, or type hours, minutes, and seconds into the three fields. Press Start to begin the countdown shown on large flip digits. You can pause anytime by pressing Start again, which turns into Pause, and Reset returns to your typed values. The repeat switch restarts the same length automatically after each finish.
Does the timer keep running if I switch tabs?
Yes, the end time is stored as a timestamp, so switching tabs or minimizing the window does not pause the countdown. The remaining time is recomputed from your device clock on every tick rather than counted tick by tick. The browser tab title also shows the live countdown, so you can watch it from the tab bar. Return anytime to see the exact remaining time.
Can the timer play a sound when it ends?
Yes, choose an alarm sound from the dropdown and set the volume slider to a comfortable level. Changing the selection plays a short preview so you know what to expect. When the countdown reaches zero, the sound plays and the page shows Time is up. Grant the one time notification permission if you also want a system note alongside the sound.
Can I link directly to a 25 minute timer?
Yes, add ?m=25 to the timer address, for example flipclockai.com/timer/?m=25, and the page opens preset to 25 minutes. Any value from 1 to 999 works the same way, so you can bookmark favorite lengths or share them with others. The recipient sees the same starting value on their own device. Press Start after the page loads to begin.
