Ratings and reviews

It's exactly what I want. Typing code-like things on a phone is tricky, but they include some of the more syntax symbols, ()/$ without needing to change your keyboard settings. Previewing the document is easy. And yeah, at the end of the day, you're writing a tex file, so you can use the cloud sync feature, or you can just copy it to run with another engine elsewhere.

Nice for 1 page doc, but some serious shortcomings for longer ones. 1. Strange bug wherein after typing a character the window moves to the end of the file. 2. No search utility, really? 3. Generating a pdf takes you to page 1, rather than where you where editing. 2023-02-14: Ah thanks, I didn't realize that "Action Toolbar" meant "Find & Replace". :)

Bad. Sensitive to syntax errors. People need to save time in crafting highly technical docs. No time for fixing errors. Also generated pdfs don't render well to complex notations. I've found an alternative that just works smoothly

What’s new

* Tabs in editor
* Keep same displayed PDF page after recompilation
