### 4/5 — Simple and Useful

*2022-02-16*

This app is exactly what I was looking for; a simple and easy to use reference for OpenGL ES functions. I have a textbook for OpenGL ES, but this app is much more convenient to pull out for a quick double-check/reminder on how a function behaves (and is easier to use than going online to the official Kronos documentation). Search bar could use some work, but I use the letter scroll bar instead for searching functions.

Also works well on macOS.

I wish there was a similar app available for Vulkan.

### 4/5 — Basic but useful

*2021-03-15*

Not a full function reference but useful. Could use some links to the Khronos source material and other GLSL references, and the search function could be improved, but just fine and valuable as a free app.

### 1/5 — So wish this didn't crash

*2016-05-28*

It's killing me as it was perfect for what I need. :(
