Documents To Go is an all-in-one iPhone editing application with support for Microsoft® Word, Excel & PowerPoint, PDF, Apple iWork and other files. It offers most of the features you are accustomed to in desktop editing software, plus it allows you to load and save files directly to and from Box. Additionally, it preserves the original formatting of your files, so edited files will come out looking as you intend them to.
To edit Box files using Documents To Go you can either "open in" from the Box app to DTG, or can log into Box directly from Documents To Go.
To login, click on the “Online” tab and select the “+” icon in the upper right-hand corner to select Box. Documents To Go uses WebDav to connect to Box, so you will need a Box-specific password to login and cannot use SSO.
You can download Documents To Go here and if you run into issues with the app can contact their support team at email@example.com.
