Unreliable
iOS user. If you like losing work, use this app! Otherwise find a different solution. Exiting with invalid syntax loses the file. Now it happened to me twice.

Almost perfect
This tool works great and would be perfect with just some UX tweaks to allow zooming and dragging when using a mouse.

More of a Mermaid Viewer than an Editor
As far as I can tell it allows you to edit the Mermaid text in one pane, and see the results in another. Not any different from editing the mermaid text in your favorite editor and then firing up a viewer in another window.
