Tornasol is now an iPhone Duo app. • Open the phone and the editor takes the whole display with the iPad's layout: the tool rail, the options bar and the Layers panel floating over the canvas, and the bar's controls in a column under the camera. • Fold it part way and the editor divides at the fold: the canvas on one page, and on the other the Layers panel at full height under a navigator of the whole picture, live, which a finger pans. Held like a book, the panels take the page beside the bar; set down like a laptop, they take the raised page, leaving the flat half to draw on. • Closed, the phone's layout, with the tools along the bottom. • Brushes follow Apple Pencil's tilt where the Pencil senses no pressure, so Apple Pencil (USB-C) draws the whole brush held upright and a thinner line laid flatter, with pressure still sizing the brush where a Pencil has it. • Two projects side by side in Split View on the open display. Also in this version: • The Layers panel's actions open in place under the selected layer: opacity, blend mode, adjustment layers, effects, mask and delete, so it is plain which layer an action touches. • The tool options are divided into groups, so each label sits with its control. • A new icon.
