iCloud Sync, and Checklist now runs on iPad and Mac.

• iCloud Sync (Pro): keep your library the same on your iPhone, iPad, and Mac, and get it back after a reinstall. Turn it on in Settings > iCloud Sync. Your lists sync through your own iCloud, with no account and no server of ours in between.
• iPad and Mac: screens adapt to larger displays. The Library shows more checklists per row, lists keep a comfortable reading width, and everything works in landscape, Split View, and Stage Manager. Checklists and menus respond to hover with a trackpad or mouse.
• Paste a list: paste from Notes, Messages, or anywhere into Quick Add, an "Add an item" field, or the editor. Every line becomes an item, bullets and numbering are cleaned up, "x2" becomes a quantity, and "Heading:" lines become sections.
• Apple Intelligence: on supported devices, Quick Add and pasted lists are understood by Apple's on-device model, messy wording, quantities, and headings included. Private and offline; nothing leaves your device.
• Quick Add shows what you typed as the checklist it will become, sections and quantities included, and a new list gets its name from you, never a guess.
• New lists get a fitting emoji suggested from their title on devices with Apple Intelligence. Swap it in a tap, as always.
• Edit in place: tap any item's text on a run or a Daily To-Do to change it right there. Touch and hold an item on any list, or in the editor, to lift it and drop it anywhere, even into another section.
• Collaborate on a Daily To-Do: invite others to your daily list and check things off together, just like a shared checklist. Free to join; hosting is part of Pro.
• Pick up where you left off: a checklist with a run in progress shows Resume next to New Run.
• Share is back as the first item in a checklist's ⋯ menu.

Everything you already use stays free, private, and offline.
