What moved #1: getting your app ready for iPhone Duo, importing prototypes into Bubble

Two stories dominated the week of November 2 to 8: apps arriving on iPhone Duo, and Bubble positioning itself as the landing place for apps built with other tools.

iPhone Duo makes apps handle two screens

iPhone Duo, the first foldable iPhone, has been on sale since October 23. Closed, it shows a 5.4-inch display; open, a 7.6-inch one, 50% larger than iPhone 18 Pro Max. Both displays share the same aspect ratio. According to Apple, apps that use standard SwiftUI and UIKit components adapt on their own, and new APIs let developers go further. On the App Store, a “Made for iPhone Duo” badge flags optimized apps, and Apple features them in editorial collections.

GoodBarber shipped iPhone Duo support for its iOS apps on November 5. Closed, iPhone Duo shows the iPhone app as it is, with the tab bar, back button and actions grouped in a rail along the camera. Open, the app keeps its layout and gains columns: a product grid goes from 2 to 4 items per row, for example. An app that’s already live needs to be rebuilt from the back office, then the update goes through App Store review. Sources: GoodBarber, iPhone Duo page and changelog.

What it changes for you: a published iPhone app now has to work on two screens, and the apps that do it well get featured by Apple. If your app is native, rebuild it with the latest SDK and test it closed, open and half-folded. For Flutter or React Native apps, and the AI tools that produce them, we found no specific announcement as of November 12: ask your tool before you ship an update.

Bubble becomes a landing place for apps built elsewhere

Bubble now lets you import an app built with another tool. Its documentation lists exports from Lovable, v0, Base44, Replit and Claude, and says any project you can export as a ZIP or HTML file can be imported. There are two ways: upload the code to Bubble, or ask an AI agent to rebuild the app through Bubble’s MCP server. Either way, you end up with a Bubble app you edit in the visual editor.

That MCP server has just landed in Claude’s connectors directory and ChatGPT’s plugin directory. It also works with Claude Code, Codex and GitHub Copilot, but not with Cursor yet. According to Bubble, it can create or edit a web app or a native mobile app straight from the assistant. Source: Bubble, “Bubble MCP” documentation.

What it changes for you: a prototype made with an AI generator is no longer a dead end if you want to keep developing it without code, and you can do it from the assistant you already use. Keep in mind it’s a rebuild, not a copy: check every screen and every data rule after the import. The documentation also doesn’t say whether an imported app can go straight to the stores as a mobile app.

In brief

• Bubble published a preliminary analysis of a security incident that began on October 26, with steps for app owners: security dashboard, privacy rules, API keys marked private, editor set to private. Source: Bubble, preliminary root cause analysis.
• Lovable added connectors, including PayPal and ActiveCampaign, plus approvals for companies. Nothing new on mobile. Source: Lovable changelog.
• Wix launched Studio Two, an editor for agencies that combines AI generation, visual editing and React code. It builds websites, not mobile apps. Source: Wix press release.
• GoodBarber now has an agent build the “Create with AI” sections of its AI Extension Builder, testing them in a browser at phone width before saving. Source: GoodBarber changelog.
