No turning needed. Just tap Start on the timer you want. ◆ Start right from your Home Screen Tap a timer in the widget to open the app and start the countdown. Each widget can show its own timer set. ◆ Check and control it from the Lock Screen See the time left on the Lock Screen, and pause, resume, or stop without opening the app. On iPhone models with the Dynamic Island, you can check and control the timer there too. ◆ Make every timer your own Name each timer, set its length, and change the screen and border colors. Show the numbers in the font you like. Only one timer runs at a time. Whether you’re settling in to focus or taking a quick break, keep the times you need ready in Timer4.
