Sururi

Your list may be long, but what matters today should always be clear. Sururi is a todo app designed to help you focus on what truly matters today—and finish the day with a satisfying sense of closure instead of an ever-growing list. Choose the tasks you genuinely want to accomplish as Today’s Focus. They stay visible at the top until they are complete, so you always know what deserves your attention next. When you are ready to begin, set a focus timer. Check the remaining time in the app, on widgets, and through Live Activities. Reaching zero does not automatically mark your task as done. You decide when the work is truly complete, allowing you to move at your own pace. Once you finish everything in Today’s Focus, close out the day with Sururi’s distinctive paper-tearing experience. It is more than another checkmark—it gives your completed day a tangible ending. Key features - Today’s Focus for keeping important tasks visible - Tomorrow’s Focus for planning the next day in advance - Focus timers with pause and resume controls - Timer progress through Lock Screen Live Activities and widgets - Subtasks for breaking larger work into manageable steps - Notes, reminders, and colors for each task - Routines for work that repeats - A backlog for tasks that do not need your attention yet - Focus history for revisiting completed days - Todo management across iPhone and Mac Sururi does not ask you to see more. It helps you see what matters now. Start today’s page with Sururi.
