Last Resort Alternative: Expo Snack

If you absolutely cannot set up the local development environment despite following all the steps above and seeking help, you can use snack.expo.dev as a last resort. However, please note:

  • Some course features will be difficult or impossible to implement in Snack
  • You won't be able to test certain device-specific features
  • The development experience will be significantly limited
  • Real-world IoT app development requires a proper local setup
