A coloring app rebuilt for the Duo, with a bigger canvas when you open it
Does Lake: Coloring Book for Adults work on iPhone Duo?
Yes, from launch day, says its developer. Lake told FoldHunt the iPhone Duo update is ready: open, a bigger canvas with the coloring tools in reach; closed, quick coloring on the cover.
- Developer claimedLake, the developer, in a submission to FoldHunt on October 12, 2026, saying the iPhone Duo update ships on launch day, and in its press kit, which shows the app closed and open on the Duo (lake-coloring.notion.site). The App Store seller is Lake d.o.o. (id 1183717726). Version 4.32.0 (released September 22, 2026) does not mention the Duo, and neither does the description.
Adapted for the fold
- Closed · Outer display
Quick coloring on the cover
Closed, Lake keeps a compact layout for quick coloring on the go, with My Works in two columns and the tabs in a rail down the right edge of the cover.
- Open · Inner display
A bigger canvas, open
Open, a redesigned, less cluttered layout gives the artwork more room and keeps the tools in reach: the brushes down the left of the canvas and the color wheel along the bottom. All Art and My Works spread to four columns.
About Lake: Coloring Book for Adults
Lake is a coloring app of hand-drawn pages by independent artists, with artistic brushes, hundreds of colors and a coloring journal. For iPhone Duo, Lake’s team rebuilt the interface for both displays. Closed, the cover keeps a compact layout for quick coloring on the go. Open, the canvas gets more room, so you zoom and tap less; the interface is less cluttered, the coloring tools stay within reach, and All Art and My Works spread out to show more drawings at once. The team says Apple Pencil support will follow once it comes to iPhone Duo. The update isn’t on the App Store yet; Lake told FoldHunt it ships on launch day.
