I am using applock app in my moto e 2nd generation from last 5 months. My experience with this app is not that good.
The main purpose of this app to secure files like pics, videos, apps etc. This app has too many ads which appears on the screen of mobile.
This is very irritating. Sometimes the ads are very long. This app works very slow in my mobile. Sometimes a secure file opens before this app. this is very bad. This app hangs sometimes while entering the password. It is difficult to use this app for first time. There is nottutorial. This app is working perfectly on lollipop 5.1 but when I update my mobile to marshmallow it becames slow. Sometimes locked apps are automatically getting unlocked. This is a big issue. Please use another app to secure your files.
