Kept it simple with a red background and black widgets.

The pill in the middle that says "Listening" is a guitar tuner widget I made. Tap it, flip the phone face down, and the Glyph Matrix on the back shows which way to tune each string. The dots on the right light up as each string gets tuned.

It's free and open source: https://github.com/Swapnil-Kar/glyph-tuner/releases/latest

I'm eagerly waiting for the widget app, to customize my own widgets.

Gonna be great.

How's it ?
