iPhone Duo UK: Will Sussex Go work on Apple’s first foldable iPhone?

Why “iPhone Duo” is one of the world’s biggest searches today

The name moved immediately from rumour to confirmed product when Apple published its official announcement on 9 September 2026. At the time this guide was prepared, Google’s country-by-country Trending Now pages showed “iPhone Duo” leading the past 24 hours in several major markets, including more than 500,000 searches in the United States, more than 200,000 in both the United Kingdom and India, and more than 100,000 in Canada.

Google Trends does not publish one combined live “world number one” table, and the displayed volumes are rounded snapshots. Even so, simultaneous top positions across several large markets show why interest is genuinely international, rather than a short local spike. You can check the changing picture on Google Trends UK and Google Trends US.

What Apple has officially announced

According to Apple’s UK press release, iPhone Duo is the company’s first foldable iPhone. It is designed to work as a compact phone when closed and a larger multitasking device when opened.

Why Sussex Go should run on iPhone Duo

App compatibility starts with the operating-system requirement. The App Store currently lists Sussex Go for iPhone with a minimum requirement of iOS 15.6. Because iPhone Duo will arrive with the much newer iOS 27.1, it clears that published minimum by a wide margin.

Apple also says developers can adapt apps to make better use of the foldable display. Sussex Go does not need to claim a special Duo interface for passengers to use the existing booking service. We will distinguish clearly between ordinary compatibility and any later interface optimisation after real-device testing.

What the foldable screen could mean for passengers in Sussex

A larger phone does not change the fundamentals of booking a reliable journey, but iPhone Duo’s multitasking design could make common travel tasks easier. Apple says Split View can place two apps side by side. In practice, a traveller could keep a booking or message visible while checking a flight board, map, hotel confirmation or train update in a second app.

What we will check when iPhone Duo reaches customers

Software compatibility can be established from the published iOS requirement, but a responsible product claim also needs real-world testing. When retail devices and the final iOS 27.1 build are available, the useful checks will be:

1. installing Sussex Go directly from the App Store;
2. creating or signing into a passenger account;
3. searching pickup and destination addresses;
4. requesting a quote and completing a test booking;
5. checking notifications, location permission and journey management;
6. reviewing the layout on both the outer and unfolded displays.

If a later Sussex Go release adds a layout designed specifically for the larger inner screen, the App Store version history will be the right place to confirm it.
