Stay focused while Twenty keeps track of your screen breaks with gentle reminders, Live Activities, Dynamic Island, and flexible focus and break cycles. Twenty is a minimalist timer built for regular screen breaks and simple focus routines. Start a focus session and get back to what you were doing — reading, studying, coding, browsing, or working. Twenty keeps track of the time and reminds you when it’s time to look away, take a short break, or begin again. 20-20-20, made simple The 20-20-20 rule is a commonly recommended screen-break habit: about every 20 minutes, look at something around 20 feet away for about 20 seconds. Twenty makes that routine easier to remember. Make the timing yours • Customize your focus duration • Customize short and long breaks • Choose how many focus cycles come before a long break • Use the default 20-20-20 rhythm or create your own focus-and-break routine Stay in the flow • Gentle notifications when focus or break time ends • Live Activities on the Lock Screen • Dynamic Island support on compatible iPhone models • Your timer continues while you use other apps Designed to stay out of the way • Minimal, distraction-free interface • Portrait and landscape layouts • Landscape mode works beautifully as a desk timer • Light and dark timer appearances Whether you’re working at a computer, studying, reading, coding, or simply trying to remember regular screen breaks, Twenty gives you a simple rhythm for focus and rest.
