🗓️Plan without friction

  • Today, Upcoming, Anytime, Incoming — a workflow, not just lists
  • Type “call mum every 2nd tue 9am” — it’s scheduled
  • Deadlines separate from start dates, like real work
  • Dependencies: lock a to-do until its prerequisite is done
  • Subtasks with progress right on the row

🔔Reminders that actually remind

  • Re-fire until you act — done or snooze from the notification
  • Recurring alarms with their own clock
  • Reminders on notes and pages, not just tasks
  • A badge that counts only what’s due right now — zero is reachable

📝More than tasks

  • Scratchpads: to-dos, notes, pages, files and hand-drawn scribbles on one surface
  • Markdown pages with a reading view, links and code blocks
  • Your own calendars (.ics) beside your to-dos
  • Custom sections, tags, pinned items, separate profiles

🔓Yours, not ours

  • Sync through your own cloud folder — Drive, Dropbox, iCloud, anything that syncs
  • Import from Things 3 and Todoist
  • Export everything, even after the trial ends
  • Unlocked by a license key that works offline, forever

Every platform. One philosophy.
