Newest version meets my needs
I love plain text and Markdown. Textastic is the first editor that really meets my needs on both Mac and iPhone. I write a daily journal on icloud drive and can update it seamlessly whether on my iPhone or my Mac. And Textastics programming roots allow me to roll up my daily entries into an annual file that is too big for other iPhone text editors to handle. I especially like the collapsed heading view that allows me to get around in large files quickly.
