Version 4 really improves DropBox support


I use this app a lot to write notes and tutorials for my courses and it has been an invaluable tool for me. For anybody with memories of old implementations of LaTeX on Mac OS (for example OzTeX), the way this app. automatically fetches packages online when needed simply seems magical.
The one main weakness for me was the shaky DropBox support. Yes, it worked, but only as long as the DropBox folder was only used to push edits done on the iOS side. Any work done on the macOS side would invariably lead to conflicts that this App was doing a terrible job of solving (pretty much, the only solution was to flush the entire folder). Fortunately, v. 4 seems to have solved virtually all DropBox problems for me. It really works the way it should. Many thanks to the developer.
The only remaining minor irritants are that the editor is limited. Yes I know that I can modify the config file to change the presets, but it is somewhat cumbersome. I used to hate the copying mechanism that the developer seems to be very proud of... I just got used to it and it doesn't bother me as much as it used to.
Anyway, this is one of a handful of apps that are absolutely essential on my iPad and that I use every day. I Love it!

Most stable Latex app at the moment


This app has allowed me to use my iPad as my primary work gadget. I like the stability of the app, and the fact that it even allows me to customize the editor to my needs.

The text selection method may take a little getting used to, and I sometimes have trouble selecting text properly using the Apple Pencil. Also, scrolling on the editor seems to be a little choppy. With the new iPad's Pro Motion technology, I hope the app releases an update to fix this.

Two improvements would be great:

1) The ability to see the pdf output side by side with the editor (another TeX app does this, but the other app has stability issues).

2) Being able to access any folder in my dropbox, and not just those in the TeX Writer folder. This makes it easier for me to switch between using my iPad when I am on the move, and my desktop when I am at home.

I think with these two updates Tex Writer will be very close to Tex experience on a laptop or a desktop. All in all I highly recommend giving this app a shot!

Does what it says


My LaTeX and TeX needs are rather rudimentary. I use it to write long documents, and for that it behaves quite traditionally for me. I like the added integration for other on-line locations such as iCloud and OneDrive. I have occasional pictures in my documents, but not an abundance, so I can't say I've "stress-tested" the app. I do, however, often use TexTastic as an editor when I want dynamic font sizing for the editor. Does what it says. I've not seen it crash and burn on anything.
