What are the best decoy/secret apps?

What secret apps are best for hiding files and other apps? Something that can maybe have a whole different lock screen... decoy icons/notifications.

Welcome.

Was this you but you're now asking in a way that's more accepted? https://forums.androidcentral.com/ask-question/909284-secret-decoy-apps.html

My apologies if it wasn't, the wording of the topic caught my eye, being so similar to the one I saw yesterday...
