LockApp

LockApp is a fast, private app lock for Android — lock any app with your fingerprint, face, or a secure PIN. A simple, super safe app locker that keeps your private apps away from prying eyes, with no ads, no accounts, and no data ever leaving your phone. WHY LOCKAPP Most app lock apps slow your phone down or ask for permissions they don't need. LockApp doesn't. It's built with a native detection engine so your lock screen appears instantly, and it never asks for the risky "draw over other apps" or "access all apps" permissions that other app lockers rely on.
