Smart App Lock Screen - App Lock Lo is a free, next-generation app lock designed for Android devices. This app provides 4-way security technology to protect your privacy, including touch password, password exposure prevention technology, and hidden features. You can lock any app, such as Facebook, Twitter, Gallery, Email, WhatsApp, Skype, and more. The patented Random Touch feature prevents others from looking into your password, and the Fake Lock feature hides the password button, pattern dots, and other sensitive information on the lock screen.

This app also allows you to create a unique cell phone screen by setting your favorite photo as a lock screen background. Unlike other apps, it offers strong security by applying a graphic touch password to the lock screen. With the Camouflage icon feature, you can replace the app lock icon with your desired icon. Smart App Lock Screen - App Lock Lo is available in 31 languages worldwide and is protected by 9 patents and 38 patent applications.
