1. Why certain reviews complain about difficulty in uninstalling Application-Locker?

A. Application-Locker is a security application, So intruders should not be allowed to uninstall Application-Locker to gain access to the locked apps. To protect locked apps from such threats, Application-Locker has an "Advanced Security" feature which will disable the uninstall option for Application-Locker in System Settings. By default this "Advanced Security" feature will be disabled. The master can always uninstall Application-Locker from inside Application-Locker itself in two clicks, No worries.

2. Why Application-Locker consumes 30+ MB at the start of application?

A. This is common for most of the Android apps as in the beginning of a service more resources are required, but this memory footprint will be reduced to less than 10 MB in 15 minutes.
