AppLock - Fingerprint is a free utility and tools application developed by Dolphin Group for Android devices. It is designed to keep your privacy by allowing you to lock your apps such as WhatsApp, Facebook, Gallery, Messages, Chats, or any other application you want. With AppLock, you can secure your apps from prying eyes and nosy friends, making it your privacy guard.

The app can lock social apps like TikTok, Twitter, Instagram, Snapchat, and system apps like Phone, Contacts, SMS, and Android pay apps such as Android Pay, Samsung Pay, Paypal, and others. AppLock can also lock any third-party app, including Gmail, YouTube, games, and more. This way, you can completely protect your privacy. The app provides a quick lock switch, alarm, and an intruder selfie feature that takes photos of invaders who enter the wrong lock screen. In addition, the app supports pattern lock, PIN lock, keypad lock, and fingerprint unlock. You can customize the app by changing the password type, button, color, and wallpaper. The app is easy to use, fast, and has a lower capacity and less memory usage.
