About this app

Signal Timer is a professional timer application designed to maximize your focus and efficiency with the power of sound and vibration.

Suitable for studying, work, training, meditation, and all your daily activities. It offers a more advanced time management experience than just keeping track of time.

Key Features
Two Modes to Choose From
Switch smoothly with a single tap between the simple and intuitive "Stopwatch" mode and the "Countdown" mode, allowing you to set a target time.

Various Signal Notifications
Minor, perfectly timed signals let you know the passage of time without interrupting your activities.

Short signals every 10 seconds

Intermediate notifications every 15 and 30 minutes

Special completion notifications let you know when the countdown ends

Each notification has a unique sound and vibration pattern, allowing you to intuitively keep track of milestones without looking at the screen.

Reliable Background Operation
Even if you close the app or turn off your screen, the timer continues to tick quietly and reliably in the background, ensuring your focus will never be interrupted.
