Many people hear the word “app” but are not always sure what it means. Apps are simply small programs on your smartphone that help you do specific things.
This guide explains what apps are and how to use them, step by step, without technical language.
What Is an App?
An app (short for application) is a piece of software that helps your phone perform a task.
Common examples include:
- Phone and messaging apps
- Camera apps
- Email apps
- Internet browser apps
- Weather and maps apps
Most smartphones come with several apps already installed.
Examples of Common Apps You May Already Have
Most smartphones come with several apps already installed.
You may already be using some of these without realising they are apps.
Here are some common examples:
- Phone – used to make and receive phone calls
- Messages – used to send and receive text messages
- Camera – used to take photos and videos
- Photos – used to view and organise your pictures
- Maps – used to find places and get directions
- Internet browser – used to visit websites
These apps are usually shown as small pictures (icons) on your home screen.
You do not need to install them yourself — they are already part of your phone.
How to Find Apps on Your Phone
- Unlock your smartphone.
- Look at the home screen.
- Apps appear as small square or round icons.
- Each icon usually has a name underneath it.
If you don’t see all your apps:
- Swipe up or sideways on the screen
- This opens a list of all installed apps
How to Open an App
- Find the app icon you want to use.
- Tap the icon once.
- The app will open on the screen.
If nothing happens, tap again gently. There is no need to press hard.
How to Close an App
You do not usually need to close apps, but if you want to:
- On most phones, press the Home button or swipe up
- This returns you to the home screen
The app will stop being used automatically.
How to Switch Between Apps
If you are using one app and want to return to another:
- Use the recent apps button or gesture
- You will see small previews of open apps
- Tap the one you want to return to
This is normal smartphone behaviour.
Do Apps Cost Money?
- Many apps are free
- Some apps cost money
- Some apps are free but offer optional extras
You are always shown the price before installing an app.
Important Reassurance
- You cannot break your phone by opening apps

Using apps becomes easier with practice.
