Ever accidentally marked a task complete? Moved something to the wrong place? Deleted an item you meant to keep? Today, I’m excited to announce that Undo has arrived in Airlist.

How It Works

On iPhone, just shake your device to undo the last action, or press the ( … ) button in the top right and select Undo… On iPad and Mac, use Cmd+Z. Airlist remembers your last 30 actions, so you can step back through recent changes one at a time.

Almost everything can be undone: completing tasks, moving items, deleting, editing names and notes, changing dates, starring items, collapsing sections, and more.

Under the Hood

Building Undo for a sync-first app presented interesting challenges. Each undoable action captures its previous state, and when you undo, Airlist reverses the change both locally and across all your devices. Deleted items are fully restored with all their properties intact. Complex operations like indent/outdent that affect multiple items are unwound in the correct order.

Try It Out

Undo is available now in Airlist on iPhone, iPad, and Mac in the App Store. Give it a shake (or a Cmd+Z) and let me know what you think. As always, I’d love to hear your feedback at help@airlist.app.
