Android has four lock options for users to lock their phone screen so that their phones can't be accessed easily by others.

App lockers, applications that can lock individual apps in more intelligent ways, are there to fill the needs. The app lockers can:

  • Better protect your private and sensitive data on Android phone;
  • Limit children's accessing to certain apps so that they won't be exposed to inappriate contents, nor will they delete your important data due to misoperation (if your data is mistakenly deleted, you may turn to FonePaw Android Data Recovery (opens new window));
  • Make it okay to not using screen lock on your phone, which is great news for those who just want to protect specific apps and hate to unlock their phone frequently;
  • Help you keep data safe when the phone are used by multiple users.

Still wondering how these app lockers work? Go on reading to learn about five awesome app lockers to protect information on your Android apps.
