I downloaded the apps and have to say that I’m impressed with the functionality. Jeff Richardson over at iPhone J.D. has a great review and admonition to read the license agreement (hint: free for non commercial use or viewing, but not editing).
These apps work great, especially on the larger screen of the iPhone 6 Plus. Again, make sure you understand the licensing issues. It is also further evidence that the big three (Apple, Google, and Microsoft) continue to push cloud use on end users.
If you have downloaded the apps, let me know your thoughts in the comments.
