GLSL Studio App Reviews

A bit overpriced at $8, but its good for messing around with shader languages.

I code professionally and I cant believe how hard it is to write in GLSL. This app is perhaps one of the best ways to learn how to write shaders. I know I will some day master OpenGL ES because of this editor. Thank you!

Easy to use. Easy to understand. Loving it. I will bump you to five star if one problem can be fixed: the normals calculated for a cube are incorrect. It makes any phong shading look bizarre (and I proved theyre incorrect by setting the normal directly to a varying and then applying it as the frag color) its easily noticeable if you make a cube with only 1 row and 1 column.

Im using and iPhone 6, iOS 8.2. The cursor is in the wrong places the text doesnt change in the input box. All manners of wonkiness make this totally unusable.
