Customer Reviews

Works extremely well

I definitely thought twice before buying this app before buying this app. However, as a young scientist, I am glad that I did. It works absolutely seamlessly with my workflow. Before leaving the office I dropped a paper that I wanted to work on over the weekend into dropbox, loaded up TexWriter, and with barely a click it automatically downloaded the new packages needed (including very usefully, revtex), and away I could go.

So far I am still just getting into the app, but I would definitely recommend it just based on what I have seen already.

Moving in text

I write paragraphs a lot using a Bluetooth keyboard, navigating through the text (technically on one line but actually on 2–3) is a massive. Overall I love it, folders and links work super well and compiling works great. Throw in XeLaTeX compiles and it's perfect for me


This is a must have for any serious researcher who's always on the move. Compiling latex documents into perfect PDFs without an internet connection is fantastic.
