You downloaded the Companion for ios? When will IOS version be available to the public? - #54 by FelixAnosike.

This is the community Samiullah for discussion of both Android and ios

Have you read Setting Up App Inventor

Connect your Phone or Tablet over WiFi explains how to use the Companion to build apps.
