Keep the to-dos and notes you do not want to forget right where you can see them. StickySort is a colorful sticky note app for the Lock Screen, Home Screen, and Dynamic Island. Capture tasks, shopping lists, plans, and ideas as individual notes, then check or sort them without losing context. Use a Lock Screen widget for quick access to a note. When you want to see a whole page, start a Live Activity from the page menu. It can display one page at a time for up to 8 hours. On supported iPhones, expand Dynamic Island to view the notes and complete checklist items. On the Home Screen, choose Page View, Pinned Note, Quick Add, Unsorted Count, Sort Reminder, or Checklist.
