Reading the review of the application you mentioned it seems it use a “hack” to achieve the lock screen but it seems to have side effects:

• “After locking phone, the device is very hot and battery down very fast. Please fix it.”

• “ sometimes after i lock the screen, the battery is getting hot until i unlock the phone”

I’m also very surprise that UWP do not offer such functionality…
