## Review summary

AppLock Master effectively secures apps like WhatsApp and gallery by locking them, appealing to users who want privacy protection. However, many users face frustration uninstalling the app due to device administrator permissions, leading to lost access when passwords are forgotten. Issues with patterns not appearing in full-screen games and concerns about the app being potentially malicious contribute to negative experiences.

- Several users perceive the app as potentially malicious or hacking their phones due to inability to uninstall easily.
