Apps are small programs that add features to your phone: video calls, medical appointments, weather, games, news and much more. For a senior discovering smartphones, the first download can seem intimidating. This guide makes that step natural.
App Store vs Play Store
App Store (iPhone and iPad)
Apple’s app store. The only place to download iPhone/iPad apps. Blue icon with a white A. Over 1.8 million apps. All verified by Apple. Requires an Apple ID.
Play Store (Android)
Google’s app store for Android phones (Samsung, Xiaomi, Oppo, Pixel, etc.). Colourful triangle icon. Over 3 million apps. Google Play Protect scans apps. Requires a Google account.
Downloading on iPhone: step by step
- Open App Store (blue A icon)
- Tap Search (magnifying glass, bottom right)
- Type the app name and tap Search
- Identify the right app: check exact name, developer, rating and reviews
- Tap Get (free) or the price (paid) > confirm with Face ID, Touch ID or password
- Wait for download > tap Open when done
Downloading on Android: step by step
- Open Play Store (coloured triangle)
- Tap the search bar at the top
- Type the app name > tap Enter
- Check: exact name, developer, rating, download count
- Tap Install (free) or the price (paid)
- Wait > tap Open when done
Free vs paid apps
- Completely free: most public service apps (NHS, tax) and some popular apps (WhatsApp, Signal)
- Free with in-app purchases: free to download, optional paid features inside (subscriptions, ad removal)
- Paid: price shown clearly before purchase, you pay once
Preventing accidental purchases
iPhone: Settings > Screen Time > Content Restrictions > In-App Purchases > Don’t Allow Android: Play Store > profile > Settings > Authentication > Require for all purchases
Permissions: what to check
| Permission | Normal for | Suspicious for |
|---|---|---|
| Camera | Photo app, video call | Calculator, torch |
| Microphone | Calls, voice messages | Card game |
| Location | Maps, weather | Puzzle game |
| Contacts | Messaging apps | Torch app |
Golden rule: the permission must match the app’s function. You can always refuse and grant later if needed.
Managing permissions
iPhone: Settings > Privacy & Security > choose category > toggle per app Android: Settings > Apps > choose app > Permissions > toggle each
Essential apps for seniors
Communication: WhatsApp, FaceTime, Signal Health: Medical booking apps, Health service apps Daily life: Weather, Google Maps, Delivery tracking Leisure: YouTube, Radio apps, Sudoku
Keeping apps updated
Enable automatic updates: iPhone: Settings > App Store > toggle App Updates Android: Play Store > profile > Settings > Auto-update apps > WiFi only
Deleting an app
iPhone: long-press icon > Delete App > confirm Android: long-press icon > Uninstall > confirm
A deleted app can always be re-downloaded free from the store, even if it was paid.
Pitfalls to avoid
- Never download outside the official store — APK files or download links in texts/emails are often malware
- Watch for fake apps — check developer name, number of downloads, and reviews
- Read each permission request — refuse anything suspicious
- Beware of free trials that auto-convert to paid subscriptions — check Settings > Subscriptions regularly
Managing storage
iPhone: Settings > General > iPhone Storage Android: Settings > Storage
To free space: delete unused apps, photos already backed up, old messages with large attachments, and clear app cache (Android).
