Philips Hue on iPhone Duo

Why foldables need their own layout

Apps designed for a single flat screen often look wrong on a foldable. Buttons end up on the fold, text gets cut off on the narrower outer display, and custom tab bars stay at the bottom when the system has moved its own bars to the side. HueCommand has been adjusted for iPhone Duo so the light controls stay easy to reach in each position.

Room tiles never sit on the fold

When the app is open across the inner display, the Rooms grid checks whether it spans the fold. If it does, it always uses an even number of columns, so the fold falls between two columns and never across a room tile. You can tap any room without aiming at the fold.

Tab bar on the side

On iOS 27.1 and later, iOS puts app bars along a side edge on iPhone Duo in most positions. SwiftUI moves its standard bars automatically, but HueCommand uses its own tab bar, so it has been built to follow. When iOS puts bars on the leading or trailing edge, the Rooms, Scenes, Automate, Effects and Settings tabs move into a column on that side. Your content is laid out beside the bar instead of underneath it.

Layouts that fit the outer display

The outer display is narrower, and together with the side tab bar that leaves little room. Screens across the app have been adjusted so they fit:

• Settings and Automate cards stack their title and details instead of cutting them off
• Accessory rows (switches and sensors) move the battery level below the name when the row is narrow
• Names wrap at word boundaries instead of being hyphenated mid-word
• Scene cards keep their color dots visible in a narrow column
• The Effects room picker shares the width instead of pushing the page sideways

The same changes help on smaller iPhones and with large Dynamic Type sizes.

Getting the most from the larger display

Unfolded, the Rooms grid adds columns to fill the extra width, up to the even number that fits, so you can see more rooms at once. If an odd number of columns would fit, the grid drops one so the fold still falls between tiles.

Folded, the outer display works well for quick switching: open the app, tap a room, done. Interactive Home Screen widgets and the Control Center control (Pro) make it faster still.

Everything else works as on iPhone

On iPhone Duo you get the full iPhone app: rooms, scenes, effects, music sync, automations, the Goodnight fade, and widgets and Control Center controls (Pro). Pairing, local control and your saved scenes are the same as on any other iPhone.

Free vs Pro: the app is a free download and everyday light control is free. Pro (monthly, yearly, or a one-time lifetime unlock) adds remote access, geofencing, multi-bridge, bridge backup, the energy dashboard, Entertainment streaming, AI scenes and more.
