This is the best app for securing your privacy for gallary, web facebook whatsaap or any other app.
Applock allows you to set pin on password to those app which cannot be secured by password and pin.
I am using this app since I boght my first android phone and it works flawlessly.
This is flawless because some of the other apps fail to lock and give direct access.ie they forget to give password interface and hives access directly.
But this app is accurate.
Fingerprint access is also there.
Now the interesting feature I liked is lock theme which is nice and asthetically pleasing.
The amazing feature also is that you can hide the app and no one can even try to tamper it.
You also have a privacy feature that prevents installing or uninstalling any app.Overall a good securuty app.
Please install it to protect your apps
