How to find, download and use apps safely
Learn how to search for, install, update and remove apps from the Play Store or App Store, how to tell a safe app from a fake one, and how to manage permissions so your phone stays clean and secure.
Apps are the small programs that make a smartphone useful — for messaging, payments, photos, maps, news and more. Knowing how to add the ones you want, and avoid the ones that could harm you, is one of the most valuable smartphone skills.
Every phone has one official place to get apps: the Google Play Store on Android, or the App Store on iPhone. Sticking to these official stores is the single most important safety habit, because the apps there are checked and can be removed if found to be harmful.
This guide shows you how to install, update and remove apps, and how to spot fakes and manage what each app is allowed to do.
How to install an app
Installing an app is simple once you have done it once. Make sure you are connected to wifi for larger apps to save data.
- Open the Play Store (Android) or App Store (iPhone) — look for the colourful triangle or the blue 'A' icon.
- Tap the search bar at the top and type the app's name, for example 'WhatsApp' or 'eSewa'.
- Check it is the real one (see the next section), then tap 'Install' (Android) or 'Get' (iPhone).
- Wait for it to download. When finished, tap 'Open', or find its new icon on your home screen.
How to spot a fake or unsafe app
Scammers sometimes create fake copies of popular apps to steal information or money. A little care before you install protects you. Look for these signs of a genuine app.
- Check the developer name. The real eSewa app is published by F1Soft/eSewa, the real Khalti by Khalti — the name shown under the app should match the official company, not a random one.
- Look at the number of downloads and reviews. Genuine popular apps have millions of downloads; a fake copy often has very few.
- Read a few recent reviews for complaints about scams or fake behaviour.
- Be suspicious of apps that promise free money, free data, or 'loan in 5 minutes' — these are common traps.
- Never install an app from a link sent by SMS, WhatsApp or a website you do not trust. Always search for it inside the official store instead.
Understanding app permissions
When you use an app, it may ask for permission to use parts of your phone — your camera, microphone, contacts, location or files. Permissions are normal, but they should make sense for what the app does.
A camera app needing the camera is reasonable. A simple torch or calculator app asking for your contacts and location is a warning sign. You can always allow or deny permissions, and change them later in Settings under 'Apps' or 'Privacy'. When unsure, deny — the app will ask again if it genuinely needs it.
How to update and remove apps
Keeping apps updated fixes bugs and security problems, and removing apps you do not use frees space and keeps your phone tidy.
- To update: open the store, tap your profile picture, then 'Manage apps' or 'Updates', and tap 'Update all' (do this on wifi).
- To set automatic updates over wifi only: look in the store's Settings for 'Auto-update apps' and choose the wifi-only option.
- To remove an app on Android: press and hold its icon, then tap 'Uninstall' or drag it to the Uninstall area.
- To remove an app on iPhone: press and hold the icon, tap 'Remove App', then 'Delete App'.
Keeping your phone clean and fast
Phones slow down when they are full of apps and files you do not need. A simple monthly habit keeps yours running smoothly without paying anyone for 'cleaner' apps — which are often unnecessary and sometimes harmful themselves.
Remove apps you have not opened in a month, clear photos and videos you do not need (or back them up to Google Photos / iCloud first), and restart your phone once a week. You do not need to install special 'booster' or 'cleaner' apps; the phone's own Settings already include storage tools.
Key takeaways
- ✓Only install apps from the official Play Store or App Store — never from SMS or WhatsApp links.
- ✓Check the developer name, download count and reviews before installing to avoid fakes.
- ✓Be wary of apps promising free money, free data or instant loans.
- ✓Allow only the permissions that make sense for what an app does; deny the rest.
- ✓Update apps over wifi and remove unused ones to keep your phone fast — you don't need paid 'cleaner' apps.
How to Find, Download and Use Apps Safely (Play Store & App Store) — FAQ
Is it safe to download apps from the Play Store or App Store?+
Yes, these official stores are the safest place to get apps because they are monitored and harmful apps are removed. The main risk comes from installing apps from outside the store (such as links in messages), which you should avoid.
How do I know if an app like eSewa or Khalti is the real one?+
Check that the publisher name matches the official company (eSewa is by F1Soft/eSewa, Khalti by Khalti), that it has a very high number of downloads, and that reviews look genuine. When in doubt, visit the company's official website and use their link to the store listing.
Why does an app ask for so many permissions?+
Some permissions are needed (a chat app needs the microphone for voice messages). Others are not — if a simple app wants access to contacts, location and files for no clear reason, deny those permissions or avoid the app. You can change any permission later in Settings.
Do I need a cleaner or booster app to speed up my phone?+
No. These apps are usually unnecessary and some are harmful. Instead, remove apps you don't use, clear old photos and videos, and restart your phone weekly. Your phone's built-in Settings already include storage management tools.
Do apps cost money?+
Most everyday apps are free to download. Some offer paid features or subscriptions inside the app. Always check before paying, and be careful with apps that ask for payment immediately or promise unrealistic rewards.
