Control with Volume Buttons

More precise. More effortless.
Button Stopwatch is a practical stopwatch app designed to be controlled with your phone’s volume buttons.
Whether you are running, training, or in a situation where it is hard to look at your screen, you can start, stop, and record laps using only the volume buttons on your phone. It helps reduce the frustration of tapping the wrong spot on the screen and lets you capture the right moment without missing the timing.
When you rotate your phone sideways, the display automatically switches to a large landscape timer mode. Unnecessary buttons are hidden, and the time is shown in oversized text, making it easy to read even from a distance while your phone is propped up.
Measured times can be saved with a single tap. You can review your running records, training best times, practice laps, and other important results anytime later.
Simple, yet fully equipped with the features you need.
Button Stopwatch is built for everyday timing, with a focus on being easy to read, easy to control, and easy to save.
