Silent timer for meetings, presentations, and libraries.
Widget instant-start, routine automation.
VertexTimer is a next-generation timer app you can rely on even when you can’t make a sound.
In meetings, presentations, lectures, or at the library—you can manage time accurately while staying considerate of everyone around you.
■ A silent timer you can trust
Timeboxing in meetings, keeping track during presentations, pacing lectures, focused study in a library.
Even in places where you can’t use sound, VertexTimer notifies you with vibration.
It can notify you in the background and even while your phone is locked.
■ Start instantly from your Home Screen
Just tap a widget to start a timer without even opening the app.
“30 minutes” before a meeting, “Pomodoro 25 minutes” when you begin studying, “HIIT 45 seconds” for workouts—
your timers are right on the Home Screen, so you can act before you even have to think.
Supports three widget sizes: Small, Medium, and Large.
Choose the layout that fits your style (Medium/Large are available with the Plus plan).
■ Automate complex schedules with Routines
With Routines, you can run multiple timers in sequence—perfect for workflows that have several steps.
