What's a good Android app for creating a lock screen that looks sealed with a zipper to prank friends or deter snoopers?

Zipper Lock Wallpapers Screen is an Android app that transforms the lock screen into a deceptive zipper interface, ideal for playful privacy or pranks. The zipper slides down smoothly when touched, mimicking a sealed barrier that can confuse anyone attempting to access the device without permission. This visual trick is useful in social settings, such as when leaving a phone unattended among friends or in public spaces, as it creates the impression of a malfunctioning or securely locked screen. Users can customize the zipper style, color, and pairing with various wallpapers, and integrate pin pad locks for an added layer of security. The app operates on an ad-supported model, allowing access to premium features like special zippers without direct payment, but reviews indicate that ads can be intrusive and appear unexpectedly. Some users report occasional reliability issues where the zipper fails to activate, but updates from FunGear inc aim to improve stability. For those seeking a lighthearted way to enhance lock screen privacy without complex setups, Zipper Lock Wallpapers Screen offers a unique blend of fun and functionality, despite the ad-heavy experience.
