Ionadol Aura puts the five classical orders — Tuscan, Doric, Ionic, Corinthian, and Composite — into your hands wherever you stand. Point your camera at a real column, set the module from a single lower-shaft diameter measurement, and watch canonical proportions from Vignola and Palladio materialize as draggable hairlines over the stone itself. The Canon Overlay is the heart of the app. Lay the member-height ladder, the entasis curve, the Ionic volute spiral, flute divisions, and intercolumniation span directly onto your photograph. Seat each line against the real stone until it fits, and the app returns a signed divergence in parts for every architectural member — shaft, capital, architrave, frieze, cornice.

Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be.
