Is App Lock & Gallery Vault Completely Reliable?

[Edward Robin]

I have been looking for an app lock for my Google Nexus 5, I have tried some but didn't find anyone much useful. Recently, I have used an app called App Lock & Gallery Vault, I am happy with it, but, not sure that it is completely reliable or not. Can anyone give me suggestion about the app, can someone please highlight some of its pros & cons?
Kindly, help me in this regard.
