Perfect timer for workouts- keeps your music going and your screen locked while your headphones continue to play

FAQ

How does the timer work in the background?

To ensure the timer functions correctly in the background, you must allow notifications for the app. This enables the app to continue its timing operations even when it's not actively displayed on your screen.

How can I add custom sounds to the timer?

You can add custom sounds through several methods. Files can be dragged and dropped onto the device via a computer connection, pasted into the app's folder from the Files app, shared from other applications, or selected directly using the '+' button within the app's Sounds tab.

What are the different timer output modes?

The app offers three distinct timer output modes: intervals, total time, and countdown. You can switch between these modes by tapping the timer display located at the top of the screen.

What is the 'Shake To Start' feature?

The 'Shake To Start' setting allows you to initiate or cancel the timer by simply shaking your device. This feature is useful when you cannot interact with the screen directly, such as during cooking, but requires the app to be open.

How do I prevent the screen from locking while the timer is running?

The 'Prevent Lockscreen' setting is a useful option that keeps your device's screen active while the timer is in operation. This ensures you can always see the timer without the screen turning off.
