Starting from early October 2015, Texpad and a slew of other apps have been experiencing download problems in the App Store. This appears to have coincided with the release of El Capitan (OS X 10.11), but there’s currently no way for us to verify that. Indeed, there is no official statement on this from Apple – there’s no acknowledgement of the problem nor is there a planned solution.

We have been inundated with emails from customers who have failed to download Texpad after repeated attempts in the past two weeks. This includes customers who have tried to restore an old purchase as well as those who purchased recently (it would appear that Apple’s payment system is not affected by the problem, just the system that governs the delivery of the app after a successful payment). Apple’s support forums are full of complaints about broken downloads for apps including Texpad, see here, here, here, here and here.

We have spent the better part of each day for the last two weeks trying to get Apple to do something about it, but have had no luck. Apple do not share users’ payment data or even an email address with us, so there’s nothing we can do to check users’ iTunes account and verify the transaction. Apple are the only party who can do that.

In light of it all, the following is the best we can recommend to our users at this stage:

New users: We urge all new customers to purchase the app directly from us. This way you will be able to download the latest version right away, start using it and if you encounter any problems (the latest version has none and is stable), we’ll be able to fix them directly.

Users with existing purchases: As for existing users, Apple have asked end users to get in touch with them directly quoting our app’s name and ID 458866234. You can write to Apple at

   https://www.apple.com/support/mac/app-store

If you do write to Apple, please email us your case ID, so we can log it centrally. If you have purchased recently, you can ask for a refund and then purchase directly from us.

Direct purchases from our web store: None of the above affects users who purchased directly from us. We have done and will always do our best to resolve the problems of direct purchases in a timely manner.

Updates:

16 Oct 2015: It appears that at least some App Store app downloads are now working. This has been tested by us on 3 computers with different OS X versions and across two geographical locations (Japan and Europe). Please try to download again before emailing us.

10 Dec 2015: This issue appears to resurface still occasionally. Once again, we’re unable to fix the download issues, so please contact Apple. (Please see this Apple support page for more: https://support.apple.com/en-us/HT203421 .)

Watch the release video for Texpad 1.6.3, a rewrite of Texpad’s interface with the following highlights:

  • Enter text faster with Texpad’s unique onscreen keyboard, written from scratch with LaTeX in mind. In addition to the familiar iOS keyboard it gives you LaTeX specific keyboard modes containing Math symbols and common LaTeX shortcuts so you never need remember them again. We have also added natural gestures to select, move, indent and comment your text.
  • Workspaces make it easier than ever to edit large multifile documents. Texpad will organise your files, list them and display a unified outline of your entire project.
  • Texpad’s upgraded autocomplete remembers commands, citekeys and label names for you, leaving you free to concentrate on writing
  • All of these features are presented in a brand new interface that makes editing LaTeX on your iOS device as attractive as it is easy.

This rewrite started out as a project to refresh Texpad’s UI for iOS 7, but having started we took the opportunity to add a number of features we have been looking forward to including for some now. In addition to the user facing changes, we have put a lot of time into speeding up Texpad behind the scenes, so this update runs more snappily than ever before, even on my now ancient iPad 1.

A very noticeable change in Texpad 1.6.3 is the custom Keyboard. At heart Texpad is a writing app, and as the keyboard is at the centre of every user’s writing experience, we redesigned the onscreen keyboard with LaTeX in mind. The beauty of an onscreen keyboard is that you can put math symbols as keys just as you can regular characters. Not only that, but can even make keys out of LaTeX snippets. Look out for a future update in which we plan to make these snippets customisable just as they are on Texpad OS X, and even make them scriptable with Lua.

Work is already underway on Texpad 1.7, a major overhaul for Desktop Texpad’s interface and also the autocomplete system common to both applications. If you are interested in participating in the beta period let us know at support@vallettaventures.com.

This post outlines reason for why we have made the decision to restrict Texpad’s Dropbox support to a single folder under user’s Dropbox. Section 1 explains why we’ve had to make such a drastic choice, whereas section 2 describes what you as the user of Texpad have to do in order to carry on using Dropbox for storing your documents.

1. Why we’re switching to a single App Folder?

From its release, Texpad had aimed to provide access to a user’s full Dropbox storage via a clean file system view. This was possible by implementing a large component in the app to deal with complexities of uploading, downloading and synchronising all files that users had marked for syncing. The component, which made use of a Dropbox toolset called the Core API has had a number of issues, most notably the sluggish load times of folder listing and duplication of files. In the past few months, this has led to a considerable number of users having issues with using Dropbox as an effective way of storing their TeX documents. With the release of iOS, these problems have intensified leading us to devise a new solution.

Earlier in the year, Dropbox released a new toolset termed the Dropbox Sync API that provides a much improved and robust support for automatically syncing files as well as their metadata. (This metadata includes among other things information on latest revisions used for resolving conflicts between local and remote copies of files in Texpad.) We’ve resisted implementing this approach due to our desire to provide full Dropbox support. This has meant continuous spending of efforts on shoring up Dropbox, efforts that would otherwise be directed to features such as the on-board LaTeX typesetter. Finally now, we’ve decided to switch to the simpler App Folder approach, much more in line with Dropbox policies. This provides a quick look up for loading files when Texpad opens a root .tex file that relies on subfiles via \include and \input tags.

2. What do users have to do?

When connecting to Texpad in v1.6.2, you’ll find a new folder called Texpad created in your Dropbox under the apps’ area. Texpad will only access these files from now on. There are two ways you can adapt to this workflow:

  • Relocate your LaTeX projects to the Texpad folder. This should be done either on your desktop with Dropbox installed or using the Dropbox iOS app.
  • Create symbolic links to your existing LaTeX projects in the folder Texpad.

As a precaution, remember to backup your data where possible.
