Expo SDK 57 and Liquid Glass - New mobile apps start on Expo SDK 57 with a new native design system, UI components, and support for Liquid Glass on iOS. Existing apps can ask the agent to upgrade.

A New Look - User dashboard is updated with a new design language, and improved support on mobile.

Test on Your Own Device - Ask for a development or preview build, and the agent sends a link to register your iPhone or iPad. Share the same link with your testers.

Screenshot Markup - Draw, add text, and crop a screenshot of your preview, then attach it to your message or download it.

Connect Your Expo Account - Connect your Expo account once, and CatDoes uses it for mobile previews and app builds.

Watch 2.0, with errors and API keys for each app in your project, more accurate stack traces, and support for Expo 57

@ File References - Type @ in the chat box to point the agent to a file or folder. Files the agent mentions are linked too, so you can open them in one click.

Files on Mobile - Open the Files tab on your phone, tap a file, then tap Edit to change it.

Support Reply Emails - When the CatDoes team replies to your ticket, you get an email that takes you back to your project to read it.

The agent never removes an API key or makes it optional on its own. It asks first, and you decide for each key.

Simpler Google and Apple Sign-In - Turning on Google or Apple sign-in for your app only takes a Client ID. No client secret or redirect URL needed.

Release Build Key Check - Before an App Store or Google Play build, CatDoes checks that your app's API keys have values and asks you to add any that are missing.

Smarter Preview - When your app uses a native library that can't run in the browser, the preview names it and offers to open your app in Expo Go.

Smoother scrolling and streaming in long chats

Support for custom build profiles in eas.json
