SidePane on iPhone Duo

SidePane turns iPhone Duo into an extended display for your Mac, over the cable or Wi-Fi, with touch and Apple Pencil support. The Mac display follows whichever screen you use, inner or cover, and resizes when you fold or rotate. Stand it up in tent mode to sign a document with Apple Pencil, or unfold it for room to show a whole reference page.
