What's New in The Rotation. Watch Collection
1.1.8
October 29, 2026
Letters from the house: a switch in Account, off until you turn it on, lets the house send a note to this phone about your register and its news. You are asked once, after you sign in; Not now leaves everything as it is, and the switch turns it off again whenever you wish. Nothing in the register needs it. When a newer version of The Rotation is on the App Store, a quiet line in the Collection says so, with the store a tap away. On iOS 26 and earlier, a watch photographed on the wrist is framed square on its case in the Mounted style, whatever the light on the skin. Smaller corrections throughout.
