What's New in Signatur
1.87
September 10, 2026
Drafts now sync between your devices, not just signed documents. • Open a contract on the Mac and it is on your iPhone a moment later, still a draft. The marks you have placed but not yet signed travel with it. • If a version signed on another device takes over a draft that still carried marks you never sent, the app now names the document instead of letting them disappear quietly. The same goes for a document deleted on another device. • While you are working, the same PDF is no longer uploaded again and again, so syncing keeps up with you.
