In the video, a person is holding a Samsung phone in their hand. The phone has a finger timer app open on the screen. The app displays two green hand icons and a timer that counts down from 5 seconds. The person's finger is shown pressing the screen, presumably to start the timer. The timer counts down from 5 seconds to 0 seconds. After the timer reaches 0 seconds, the person's finger presses the screen again, and the app displays a message that says "Press Start to start the timer." The person's finger then presses the screen again, and the timer starts counting up from 0 seconds. The video ends with the person closing the app.
