> Find details of the latest improvements and updates here
**September 29-30, 2026**
Agent testing for everyone, iPhone Duo previews, GPT-6.1 Sol
A native Swift game on iPhone Duo in the cloud simulator
* **Agent testing** is on for every Web app and Mobile app project. After it changes your app, the agent opens it, clicks through what it built, and fixes what it finds. You can watch it live in the preview under **Agent is testing your app**. See [Agent Testing](/docs/features/agent-testing.md).
* In the Vibecode iPhone app, your preview stays on screen and usable while the agent works
* Native iOS apps can now be previewed on **iPhone Duo**, the foldable iPhone. On the web, use the device switch in the preview toolbar, then fold and unfold to test both displays.
* If you leave a native iOS preview idle for an hour, the simulator pauses and asks **Are you still here?** Tap **I'm still here** or send a prompt to pick up where you left off.
* Installing a native iOS app now checks your backend first. If it was never deployed, deploy it before you install. If it has changes you haven't deployed, choose **Deploy backend** or **Install anyway**.
* Connect Apple for native iOS apps by signing in with your Apple ID, and Vibecode creates the App Store Connect API key for you. On the web, see, replace, or disconnect your Apple credentials under **Apple Developer** in **Settings**.
* **Hard reset** on a native iOS preview no longer waits for a full rebuild when your app is already built
* Read the [Native iOS Apps guide](/docs/getting-started/native-ios-apps.md)
* **GPT-6.1 Sol** replaces GPT-6 Sol in the model picker and is the default for follow-up prompts. It's also in the APIs tab for your apps.
**September 28, 2026**
Built on iPhone
Introducing Built on iPhone
* **Built on iPhone**: describe an app in the Vibecode iPhone app and the agent writes the Swift, builds it, and tests it in a cloud simulator. Then [install it on your home screen](/docs/getting-started/native-ios-apps.md#install-on-your-iphone). No Mac or Xcode needed.
* **Claude Sonnet 5.5** replaces Claude Sonnet 5 in the model picker, and is in the APIs tab for your apps
* New referral rewards: you and your friend each get $1 when they sign up with your link (for your first 5 referrals), plus a one-time bonus for both of you when they first subscribe (Plus $10, Pro $20, Max $50 each). See [Referral Program](/docs/getting-started/plans-and-credits.md#referral-program).
* On the web, queued prompts are saved with your project, so they keep running if you refresh or close the tab
* After your first prompt on the web, Vibecode offers to turn on browser notifications so you know when your app is ready
