As you use an app to explore a lesson or solve a problem, you add data and denitions in one or more of the
app’s views. All this information is automatically saved in the app. You can come back to the app at any time
and all the information is still there. You can also save a version of the app with a name you give it and then
use the original app for another problem or purpose. See Creating an app on page 105 for more information
about customizing and saving apps.
With one exception, all the apps mentioned above are described in detail in this user guide. The exception is
the DataStreamer app. A brief introduction to this app is given in the HP Prime Graphing Calculator Quick Start
Guide. Full details can be found in the HP StreamSmart 410 User Guide.
