OTASK is a visual 24-hour day planner that puts your entire day on a single clock face—so you can actually see where your time goes. Instead of endless lists, your tasks live on a clean 24-hour dial. One glance shows what's now, what's next, and how much of your day is still open. It's calm, focused, and refreshingly simple. WHY OTASK • See your whole day at once Every task and reminder sits on a beautiful 24-hour dial. No clutter, no noise—just a clear picture of your day. • Plan in seconds Swipe up to add a task, set a start and end time, and you're done. Drag any block on the dial to reschedule instantly. • Routines that plan ahead for you Build your recurring days once—morning routine, work, workout, sleep—and let OTASK fill them in automatically for the days ahead. • Never miss what matters Get timely notifications for tasks and reminders, and follow your current task right on the Lock Screen and Dynamic Island with Live Activities. • Widgets at a glance Keep your day in view with Home Screen and Lock Screen widgets. • Your day, on every device Everything syncs privately through iCloud, so your plan is always with you on iPhone and iPad. • Designed to disappear A minimal, monochrome interface that stays out of your way and helps you focus on the day—not the app. OTASK is for anyone who wants to be more intentional with their time: students mapping out study blocks, professionals time-blocking their workday, and anyone building better daily habits. Plan every day with clarity. Download OTASK and take back your 24 hours. — Membership OTASK offers a free trial, after which full access continues with a Monthly, Yearly, or one-time Lifetime purchase. You can manage or cancel your subscription anytime in Settings.
