I have downloaded app lock recently only and it is still running in my phone but I am not agree with the process that whenever I try to open any app which is associated with AppLock first the picture of the AppLock appears and then the block office which is not a good thing well I found that it is of no use.
But there are many advantages also it this app is very easy to use we can easily open any app with app lock and we can also reset the password of AppLock using email or phone number but the features are limited if you want more features then you have to buy a paid version then also it is a very good version without buying a paid version but other problem is that it is very slow.
Looking at its advantages and disadvantages, there are more disadvantages of it but that is worth using once.
