TeX - LaTeX Stack Exchange is a question and answer site for users of TeX, LaTeX, ConTeXt, and related typesetting systems. It's 100% free, no registration required.

I would like to know if there is a tablet device (iPad, Nexus...etc) on that one can install a full LaTeX environment. By "full", I mean that:

One can produce (compile successfully) from any `.tex` file the dvi or PDF file.
If any package is missing, one can install it manually (or better automatically, as MikTeX).

After searching on Google, it seems to me that there is no such tablet device. Most of LaTeX editors on tablet device requires internet connection (compile .tex on a server). In this post http://tex.blogoverflow.com/2012/09/i-tex-therefore-ipad-reloaded/, the author mentioned that TeX Writer (UK store) (for iOS) doesn't require internet connection. But it looks like it is just an latex editor. I don't know how it works with LaTex. (Does it provide a mini-latex environment or something else?).

ps. Of course I don't want to type .tex file on a tablet device for a long time. But sometimes I may need to modify an existing .tex file (eg. when I find some errors in my paper).

TeX Writer compiles the files on the iPad, and so does TexPad (which also has the capability to send the send a file to a server to be compiled remotely) –  Guido Nov 17 '12 at 17:35
    
@Guido, do you know Tex Writer and TexPad work with LaTex? I mean they provide a (mini or full) LaTex environment or the users need to install LaTex distribution themselves? –  user565739 Nov 17 '12 at 17:38
    
They work with LaTeX and they have several packages preinstalled, and you can install further package. They are usable. –  Guido Nov 17 '12 at 17:41

Earlier today I was contemplating putting this on my android tablet, if you have debian linux you could install the arm texlive distribution... play.google.com/store/apps/… –  David Carlisle Nov 17 '12 at 18:25

Texpad developers here. The answer is yes - you can do this on the iPad with Texpad. Texpad for iOS has had a built in LaTeX typesetter, no internet connection required. Most commonly used LaTeX packages are now included, and we expand the distribution with every update (9 updates in the past three months), and it is now so good that one user edits LaTeX on his Mac and typesets on his iPhone because the distribution is leaner, simpler and faster.

PGF drivers are underway right now and the update with local TikZ/Beamer typesetting should be ready for download in February.

In addition to the onboard typesetter, we still provide free cloud typesetting servers with the entirety of TexLive 2012 installed. If you have any further questions, email us at support@vallettaventures.com.

UPDATE: Tikz and beamer are now working in 1.5 and later releases. In addition all the fonts plus latex and bibtex packages are downloadable using the Bundle Manager in Texpad now: http://support.texpadapp.com/kb/typesetting-ios/latex-bundle-manager-on-texpad-ios . Check it out and let us have your feedback via 'Contact Us' form on http://texpadapp.com .

Does the logicool keyboard for ipad works with Texpad? –  Marcos Villagra Aug 30 at 8:15

Just have a look here: TexPortal. This is an App for Android which runs on my Nexus 7 without the need for root and an internet connection. I didn't try to compile very complex documents but for some of my simple business letters it works perfectly. Keep in mind this is only the compiler not an editor! The sources and the installation guide you can find here: https://github.com/anhoavu/TeXPortal.

This answer only concerns the iPad.

I'm not going to reproduce my blog post (already linked in the question) as it is still relevant. I'll highlight a couple of points directly related to your question.

One can produce (compile successfully) from any .tex file the dvi or PDF file.

Taking the "any" at face value, the answer is "Not yet". There are (at time of writing) two iPad applications that can compile a tex document on the iPad without needing internet connectivity. One of those is TeX Writer, the other is TeXPad. Neither can compile any tex document. TeX Writer currently uses unadulterated TeX, meaning that it doesn't have the e-TeX extensions and produces DVI (which it then converts to PDF). So anything that uses the e-TeX extensions does not currently compile (nor XeTeX nor LuaTeX). TeXPad is based on KerTeX about which I know very little.

But with that taken into account - and with the knowledge that they are both in their infancy - it is now possible to compile documents directly on an iPad with no internet connection. Both come with the LaTeX format, TeX Writer also includes a plain TeX format.

If any package is missing, one can install it manually (or better automatically, as MikTeX).

Both of these applications allow installation of packages, neither is automatic.

I wrote an app to meet this need on my Android. It can also output PDFs. It renders TeX in real time.

This may be be a kludge, but if you have a rooted Android device, one can dual-boot various flavors of Linux (there are apps that will help in the installation process). Inside Linux, one can install texlive and compile anything you would like.

Welcome to TeX.SX! You may have a look on our starter guide. –  mafp May 22 '13 at 21:11

TeX Writer on both iOS and Android is a LaTeX editor and compiler for tablets. It has a minimal distribution. Additional packages can be downloaded automatically on demand.

iOS App Store:

Google play:

(Disclaimer: I'm the developer of VerbTeX)

VerbTeX may be an alternative. It's available for Android, iOS and Windows 8. It uses a full (and up-to-date) TexLive distribution in the background to generate PDF. So there's generally no need to install any missing packages (since no packages are missing). If you create custom packages you can also simply upload and use them.
