This is not a stand alone application. Themes require Kustom Live Wallpaper PRO (Not the free version of KLWP).

What do you need:

✔ Kustom (KLWP PRO)

✔Hide Status Bar

(OBS) Open the KLWP then go to the global tab Where you can change Your Walls, Colors and most of the stuff.

All These Themes Were Made With a S8+ Device And you are going to need to make some tweaks
