 # What is that name?
-I didn't know that the name OptiDice was already being used by a company that makes dice, I just thought "Hey I want to make dice optimized for watches" so from "Optimize" and "Dice" I ended up with OptiDice

 ## Are the dice really optimized?
 Opening the app takes a little while and opening the menu for the first time freezes for a second but the rest of the time the app runs really smoothly. I tested with quite a lot of dice and it worked pretty well (on the Galaxy Watch 4 at least)
+
+Also I created a custom shader for the dice that should improve performance (and graphics), no actual lights or physically based rendering is being done, it's simply Gouraud shading without specular reflections on the vertex shader and an extra "light" being multiplied in the fragment shader when the object is below a certain Y coordinate.
