Silent and visual timers
Sound isn't always an option. These timers signal with a full-screen colour flash, a phone notification, or a large visual countdown instead — and there's an extra-loud option for the opposite problem.
Use a silent timer in a library, shared office or sleeping house; a notification alert when the phone is in your pocket or locked; a large visual countdown when a whole room needs to see the time left; and the loud alarm timer when the kitchen or workshop is noisy.
No-sound alerts
Screen flash and haptics instead of an alarm.
Visual countdowns for a room
Big digits and colour phases everyone can read.
When you need it louder
For noisy rooms or when you walk away.

Frequently asked questions
How does the silent timer tell me time is up?
The whole screen flashes red for several seconds and the digits turn red. No sound plays at any point, so it's safe in a quiet room.
Can a web timer vibrate my phone?
No website can vibrate an iPhone, and Android blocks vibration in background tabs, so Tickline uses a silent full-screen flash instead. To be alerted after leaving the browser, add Tickline to your Home Screen and allow notifications.
Can students at the back of a classroom read the countdown?
Yes. The classroom timer uses oversized digits and turns amber then red in the final seconds, which reads clearly from across a room or on a projector.
