Shapely 3D 1.3 is built for iPhone Duo. Two screens, one project, and a hinge we treat with the respect it deserves. MADE FOR IPHONE DUO - Shapely 3D runs at the native size of both screens. Closed, the outer screen is the whole editor: the catalog, the gizmo, Edit Points, booleans, the printability check. Open the phone and the same project gets more workplane around it, with your selection and your camera right where you left them. Nothing is letterboxed, nothing hides behind the fold, nothing asks you to start over. - Built with Xcode 27.1 and the iOS 27.1 SDK, so the phone is treated as what it is, not as a tall iPhone with a line down the middle. The line is a feature. We checked. PRINTABILITY, NOW WITH A SENSE OF PROPORTION - The check now tells minor mesh issues from ones that need repair. Hairline gaps, slivers and a few flipped triangles - the kind every slicer closes on its own, and the classic 3DBenchy is full of - get a quiet grey mark and a "Minor issues" status that says the model prints as it is. No export gate, no lecture. The orange warning, "Needs repair" and the question at the door are kept for holes and inside-out surfaces a slicer would get wrong. Benchy has printed a million times. It did not need our opinion. ALSO NEW - The projects home now recommends one other independent app, through Kickstart Exchange - matched by app, not by you: no tracking, no identifiers, no "based on your activity". Shapely 3D Pro never sees it. Pro is ad-free, and stays that way. - The Pro screen opens with the Pro artwork - the app icon with its sparkles, the same picture the App Store shows for the purchase - instead of a generic sparkles symbol. It borrowed a symbol for three releases. It has its own picture now. FIXED - Importing an STL from Files or iCloud Drive works again on iPhone and iPad. In 1.2.0 it said "could not import" to every file you picked, which was true, and unhelpful. - Fixed a crash on iPad that could close the app while moving, rotating or scaling an object. Of all the moments to leave, mid-drag was the worst one. Everything from 1.2 - the printability check, Repair, Import USDZ, the Printing tab - is right where it was. Folded or not.
