The name DataViz might be familiar to those who have been using mobile devices long enough to remember the ancestors of today’s smartphones. The company, popular for its mobile office software, has just announced the latest and greatest version of Documents To Go for Android, which may sound so sweet and delectable, but might also be a bit of a bitter pill to swallow.

It’s been more than three years since DataViz released its last major version of its Documents To Go app for Android. That version was showing its age, with a visual design that matches the style of Android days gone by. Version 4 of Docs To Go now sports a new style that matches the flat UI design trend that seems to be prevalent these days. But more than just visual flair, the behavior and workflow of the app has also been improved, making it easier for users to navigate through their documents and edit them.

But perhaps the biggest highlights of this release revolves around the cloud and document editing. Documents To Go now supports not just one but multiple cloud storage options, including Dropbox, Google Drive, Microsoft OneDrive, and others. This enables users to have a one-stop-shop for all their documents and editing needs wherever they may be. And starting with this release, even free users will be able to edit documents at no cost, unlike other mobile office suites that only let free users view but not modify files.

Unfortunately, some of these feature come with a price, literally. While the app itself is free, which includes editing of documents, other features are available only as in-app purchases. Adding cloud services support will cost you $4.99 while the ability to sync with Windows desktops is yet another $4.99 purchase. Even opening password protected files has a $4.99 price tag. If you want all those features anyway, you can opt to just purchase the Premium Pack for $9.99.
