TASKS & PROJECTS Organize work into projects with boards, lists, and Focus Now mode. Set priorities, due dates, tags, and recurring schedules. Move tasks between projects with a tap. RICH NOTES Write with a full editor — headings, bold, lists, code blocks, images, and more. Embed index cards, link notes to tasks, and use keywords to organize. CALENDAR & SCHEDULE Plan your day with events, timeblocks, and weekly/monthly views. Sync your Google Calendar. Track time with a floating timer that shows what you're working on. TIMED ROUTINES Build step-by-step routines with countdown timers and voice cues. Morning routine, workout, study session — each step timed and announced. Track streaks and consistency. HABITS & COUNTERS Track daily habits with streaks. Use counters for anything you want to count — water glasses, pushups, pages read. Reset daily, weekly, or never.
