What Are Apps and How to Use Them

Apps are what make your smartphone useful beyond just making calls. Think of them as different tools, each designed to help you do something specific.

What is an App?

"App" is short for "application" - it's simply a program that runs on your phone or tablet. Each app does something different, just like different tools in a toolbox.

Think of it This Way

Your phone is like a Swiss Army knife. It comes with some built-in tools (apps), but you can add more tools (download more apps) whenever you need them. Need to check the weather? There's an app. Want to video call family? There's an app for that too.

Apps You Already Have

Your phone came with several useful apps already installed:

Are Apps Free?

Most popular apps are free to download. If an app costs money, it will show the price instead of "Get" or "Install." You can use your phone without ever paying for an app.

App Safety Tips

Only Download from Official Stores

Always use the App Store (iPhone) or Play Store (Android). Apps from these stores are checked for safety.

Check Reviews and Ratings

Before downloading, look at the star rating and read a few reviews. Popular, well-rated apps are generally safe.

Be Careful with Permissions

Apps may ask to access your camera, location, or contacts. Only allow what makes sense - a photo app needs camera access, but a calculator doesn't.

Delete Apps You Don't Use

If you downloaded an app and don't use it, you can delete it. This frees up space and keeps your phone organized.

How to Delete an App

iPhone

Press and hold the app icon until it wiggles. Tap the minus sign (-) or "Remove App," then "Delete App."

Android

Press and hold the app icon, then drag it to "Uninstall" at the top of the screen. Or go to Settings → Apps, find the app, and tap "Uninstall."
