Here is a quick comparison/review of all Markdown editors for the modern Windows interface. The selection is limited to the editors with a side-by-side editor and a live-preview pane. (Which only excluded three apps.) Not to spoil the fun, but you get to choose between plague and cholera.
Warning: These apps are likely to cause data loss and frustration! The quality isn’t all that great.

- Terrible app bar layout
- Cannot scroll in unfocused area
- No sharing
Notes:

Conclusion
I can’t recommend any of the available apps. They are quirky, unfinished, unpolished, and don’t do their task well. Most are likely to cause you to lose data.
The reviews are sorted by their popularity rank in the Windows Store at the time of publishing. There were no paid options available, so all apps are free of charge.
