1. AppLock – Fingerprint & Password Lock
AppLock is one of the most popular mobile screen lock applications due to its powerful security features. It allows users to lock apps, gallery, messages, settings, and even system functions using PIN, pattern, or fingerprint. One of its strongest features is intruder detection, which captures a photo when someone enters the wrong password.
AppLock also supports hiding notifications, locking new apps automatically, and using fake error messages for extra privacy. Despite its advanced options, the app is easy to use and works smoothly on most Android devices.
2. Norton App Lock
Norton App Lock is designed for users who want strong security with a clean and simple interface. It provides app locking using PIN, pattern, or fingerprint without showing ads, which improves user experience. The app focuses purely on protection rather than unnecessary customization.

3. Smart AppLock
Smart AppLock offers flexible locking options along with smart automation features. Users can lock apps with pattern or PIN and set rules based on time or location. For example, selected apps can remain unlocked at home but locked in public places.
The app also includes stealth mode to hide its icon and a widget to quickly enable or disable locks. It is lightweight, fast, and suitable for users who want both convenience and privacy.
4. Gesture Lock Screen
Gesture Lock Screen is perfect for users looking for a unique way to unlock their phone. Instead of traditional passwords, it allows custom gestures such as letters, numbers, or symbols. This makes unlocking faster and more creative while maintaining security.
The app provides gesture sensitivity control, preview options, and vibration feedback. It is especially useful for users who want something different from fingerprint or PIN locks without compromising safety.
