Closed

## Closed, the bars line up along the camera

Turn iPhone Duo: tab bar, back button and actions follow the camera into a rail, and change sides with the phone. The layout your users know stays the same.

GoodBarber’s engine places your app’s bars in the rail itself. **Nothing to set up.**

## Questions about iPhone Duo

**### Do I need to redesign my app?**

No. Your fonts, colors and layouts stay the same. Closed, iPhone Duo shows the layout of your iPhone app; open, the same layout with more columns.

**### What does my app do on iPhone Duo before the rebuild?**

It runs. Open, it shows at iPhone size in the center of the inner display; closed, it uses the outer display, to the left of the status bar and the camera. After the rebuild and the published update, it fills the inner display.

**### I am creating my app now: is it ready for iPhone Duo?**

Yes. New apps are built with the current engine, which supports iPhone Duo. You publish them to the App Store and Google Play from your back office.

**### Which bars move into the rail?**

Those that display as icons: the back button, shortcuts, the Bold, Minimal and Floating tab bars, and the actions of a detail page. The Clean and Classic tab bars, and a Bold tab bar without icons, stay at the bottom: the rail stops above them.

**### Is there a rail when iPhone Duo is open?**

In landscape, yes. In portrait, the bars stay at the top and the bottom of the screen.

**### Does what I was doing continue when the phone opens or closes?**

Yes. A podcast or a radio keeps playing, and a long text stays where you were reading.

**### Does anything change on Android, the PWA or iPad?**

No, nothing changes.
