Regardless of whether you want to keep someone out of your files, change your privacy settings quickly, or make sure you’re data can’t be accessed, app locking your Android phone is a great solution.
Many app lockers come with claims of being completely safe, yet not all of them do their job well. To help you decide, this guide looks at the best App Lock Apps for Android in 2025 and discusses what they do well and what they lack.
What is an App Lock & Why You Need One
App Lock Apps for Android is an app that helps you secure chosen apps on your smartphone by asking you to enter a password before anyone else can use them. It adds another layer of defense so that if someone gets control of your phone when it isn’t locked, they won’t be able to use your secure applications without entering a password.
