Converting MIT Appinventor APP to IOS

No, this is not possible. Android apps work on Java and use .apk files. And it is not possible to convert/ run .apk files on iOS devices.
Refer: App Inventor apps for iOS
Refer: StackOverflow

No this is also not possible and currently in closed beta. Refer the same link as I posted before. However, you can develop apps for android devices using Chrome or Firefox browser in your PC and Apple computer too :slight_smile: . I use Windows so I don't know about MacOS devices.much.

Hope this helps!
