The ultimate template for divinely proportioned apps.
This is not a fixed grid. It's rather a collection of widths and heights based on the topbar-height of 88 pixels. Any of the given sizes relate to each other according to the golden ratio.
Use the measurements for your margins, buttons and boxes and you're good. And remember to break the grid once in a while. That's when it gets exciting.

Have fun! I'm excited to see what you create with it.
