App Inventor runs through a Web browser. If you're using a phone, you work with the phone connected to your computer by a USB cord. Your app will emerge on the phone bit by bit as you work. If you don't have a phone, there's a phone emulator included with the App Inventor setup package that you can use instead. When you're done building, you can "package" your finished app to produce an "application package" (Android apk file) that can be shared around and installed on any Android phone, just like any other Android app.
