How to make hidden UI on Android

[Android Central Question]

Hello. Is there any application that can allow to create a hidden User Interface on android Phones. Idea simple. You meet with gang and they ask to show your phone. You do not like them to see any mobile bank application, some mobile wallet app, you do not like them to see that you have email installed.

But if you use some special pin, then you can use all apps.

Thanks

Tons of apps that do that. Secure Folder or Secure App should do the trick if you search that in the app store. Some phones include a similar feature, like Samsung's devices.
