You parked somewhere near the stadium or bar, but when the concert/party ends you don't have a clue where the car is. The friends you came with are equally as clueless. Fortunately you haven't lost your Android phone that never forgets anything, and you remember you have the hot new app, Android, Where's My Car?. With this app, you click a button when you park your car, and the Android uses its location sensor to record the car's GPS coordinates and address. Later, when you reopen the app, it shows you a map from where you are to the remembered location-- problem solved! With this tutorial you'll be able to download a created app and then study the annotated blocks below to better understand the app and App Inventor programming in general.

With these beginner-friendly tutorials, you will learn the basics of programming apps with App Inventor.

Follow these four tutorials and you'll have four working apps to show for it! After building the starter apps, which will take around an hour, you can move on to extending them with more functionality, or you can start building apps of your own design. Get started now with Hello Codi!.

Colored Dots is a simple painting program that uses a second screen to select the paint colors. This tutorial serves as an introduction to creating apps that have multiple screens.

The location sensor object is used to communicate with the global positioning satellite receiver (GPS) in your phone/tablet. When the LocationSensor communicates with the built-in GPS receiver, the GPS can determine the location of your device.  The sensor can also work with network/wifi location services.  Finding a location using the network uses very different techniques to determine a location. Location means, the device's present latitude and longitude or it can mean your street address.
