One of the online courses I took stated that a desktop or laptop is a prerequisite because you cannot use LaTeX on a mobile device. That turns out to be not entirely true. There are, in fact, websites and apps that allow mobile LaTeX authoring.

I am currently using VerbTex to do my writing and formatting. The free version is limited to only four images, so I’m copying-and-pasting to Overleaf to translate it to PDF.

If you don’t mind subscribing and paying a few euros per month, VerbTex is definitely easier to use. And, it seems to work. Overleaf works, but, like many other online editors, you have to carefully watch what you’re typing.

If you are new to LaTeX, this tutorial is very helpful. It doesn’t cover everything, but it’s a good start. I also suggest downloading a template, because they have easy-to-modify code and comments.
