## Review summary

Reviewers broadly praise App Lock for its easy, no-nonsense interface and simple, free locking solution, with several calling it the best or secure option. However, reliability issues dominate: the lock often fails to engage or only works when the app is opened, so permanent protection isn't guaranteed. Some users report crashes or instability, and there are instances where locked apps don't reflect correctly. A common request is to add stronger protections, such as preventing the uninstall of other apps. Overall, the app is popular but hampered by consistency problems and feature gaps across devices.

### Pros

- Easy to use with a simple, no-nonsense interface.
- Generally positive reception, with users calling it the best or secure lock.
- Free to use.

### Cons

- Reliability issues: locks often fail to engage or only work when the app is opened, so permanent protection isn't guaranteed.
- Not permanently enforcing locks; locked apps can still be accessed without the password in some cases.
- Stability problems: occasional crashes or the app stopping unexpectedly.
- Missing security features requested by users, such as preventing uninstall of other apps.
