All platform markdown editor?

[metllicamilitia]

I mostly use Apple devices, however I do have a Lenovo Yoga 710 series, and a Moto G5 Plus. I was looking into doing more writing on the Yoga and I currently use Byword on my Apple devices, however, I’m trying to find a decent to good markdown editor that can be used on all the platforms. I don’t like the layout of Word or paying Microsoft $100/yr for Office just to use Word occasionally. Does anyone have any suggestions?
