Stop overthinking. Start a timer. Get it done. iTimeBox is a focus timer that turns big, intimidating goals into small, achievable sessions. Pick an activity, set a duration, and commit. No multitasking, no distractions — just you and the task in front of you. When the timer ends, you've won. Every completed session is proof that you showed up. WHY IT WORKS Most productivity apps track what you did. iTimeBox changes what you do next. By committing to a focused block of time — even just 10 minutes — you overcome the resistance that keeps you from starting. Use it for anything: studying, exercise, physical therapy, language practice, deep work, creative projects, or breaking a procrastination habit. FLEXIBLE BY DESIGN • Set a minimum duration to push through tasks you avoid • Set a maximum to keep enjoyable activities from consuming your day • Create multi-stage sessions with warm-up, focus, and cool-down phases • Works with Timeboxing, Pomodoro, GTD, or your own approach BUILT FOR MODERN iOS • Live Activities — see your timer on the Lock Screen and Dynamic Island • Widgets — start sessions right from your Home Screen • Siri — start and stop sessions with your voice • iCloud Sync — your activities and history stay in sync across devices • Session History — review your progress with a contribution-style activity graph • Export — take your data with you THE GOAL ISN'T PERFECTION iTimeBox is built around a simple idea: showing up consistently matters more than measuring outcomes. Ten focused minutes on physical therapy, language practice, or a creative project adds up. You don't need to be perfect — you just need to start.
