Spy App Features Explained: What You Can (and Can’t) Monitor in 2025
Spy apps (also known as parental control or monitoring apps) have evolved rapidly in the last few years. In 2025, they are more powerful, more precise and—most importantly—easier for parents to use. But many buyers are confused about one thing:
What can spy apps actually monitor… and what is still impossible or restricted?
This guide explains the real, practical features you can expect from today’s top monitoring tools like mSpy, uMobix, and Eyezy — and also what they cannot see due to legal and system limitations.
What Spy Apps Can Monitor in 2025
Modern monitoring apps can collect a massive range of data from Android and iOS devices. Below is a breakdown of the most common features.
1. GPS Location & Route History
All top apps (mSpy, uMobix, Eyezy) provide:
- 📍 Real-time location
- 🧭 Route history
- 📌 Geofencing alerts (when the device enters/exits an area)
This is the most reliable and accurate monitoring method across all devices.
2. Phone Calls & SMS Logs
Spy apps can track:
- 📞 Incoming & outgoing calls
- ⏱️ Call duration
- 📱 SMS messages sent & received
- 👤 Contact information
Call recording is more limited in 2025 due to OS restrictions (details in the “What You Can’t Monitor” section).
3. Social Media Monitoring
This is where premium apps shine. Depending on the platform and OS, spy apps may monitor:
- 👻 Snapchat
- 💬 Facebook Messenger
- 📱 Telegram
- 🎵 TikTok
- 📧 Gmail & email apps
Among these, uMobix and mSpy offer the deepest social media coverage, especially on Android devices.

4. Deleted Messages & Files
This depends heavily on the app:
- mSpy: Best for recovering deleted messages (WhatsApp, Snapchat screenshots, SMS)
- uMobix: Shows “live” messages but doesn’t store deleted history as deeply
- Eyezy: Shows previews and activity logs
👉 Try mSpy — Best for Deleted Data Recovery
5. Screen Time, App Blocking & Web Filtering
Especially important for families:
- ⏳ Daily screen-time limits
- 📵 Block apps (TikTok, games, etc.)
- 🌐 Filter adult websites
- 📱 Schedule device downtime
Eyezy is the leader here due to its child-friendly controls.

6. Keystroke Recording (Android only)
Keylogging allows Android users to see:
- Typed messages
- Usernames/passwords
- Search queries
iOS does not allow keylogging without jailbreaking.
7. Stealth Mode (Invisible Mode)
Most spy apps remain invisible once installed:
- No app icon
- No notifications
- No battery drain indicators
Examples:
What Spy Apps Cannot Monitor in 2025
Despite impressive technology, certain things remain impossible or restricted due to privacy laws and OS security.
1. No Access to End-to-End Encrypted Messages Without Permissions
Apps like:
- Signal
- iMessage
- WhatsApp encrypted backups
cannot be fully accessed unless the spy app has device-level permissions. Even then, **iMessage is extremely limited on iPhone**.
2. No Call Recording on Most Modern Devices
Due to Android 10+ restrictions and iOS privacy regulations:
- 📵 Call audio cannot be recorded consistently
- 🛑 Internal audio recording disabled by OS
Only a handful of devices still allow it.
3. No Access to Secure Apps or Vaults
Apps like:
- Secure Folder (Samsung)
- Private Vault apps
- Password Managers
cannot be accessed due to encryption.
4. No Remote Installation Without Device Access
In 2025, **you cannot install spy apps remotely on private personal devices**. You always need at least:
- One-time physical access
- Or access to the device owner’s cloud account
5. No Monitoring Without Legal Permission
Spy apps are legal ONLY when used for:
- 📱 Monitoring your child
- 💼 Monitoring your company-owned devices
- 🧑🤝🧑 With explicit consent
Anything else violates privacy laws.
