App to lock screen Android

I am looking for an app to lock my Nexus devices screen. I have my device setup that it requires a password, but not as soon as the device is locked only after X amount of minutes. The current lock screen app I have locks the device fine, but requires me to enter my password as soon as I go to unlock the device again. If I hit the hardware lock button it does not require my password right away when I go to unlock the device. Do you guys know of any apps that would lock my screen but not require password input until X amount of minutes has occurred?

Thanks for the help.

On my Nexus 5, I can make it locks right away as soon as I press the lock button by choosing 'Immediately' on settings.

That doesn't answer my question at all. Thank you for trying though.

In lock screen settings it should let you decide immediately, 3 min, 5 min, 15 min, etc.

It does. I have it set up how I like. But when using an app (a software button) to lock my device the app ignores my settings and requires password entry immediately as stated in the original post.
