[Top ten] Great
This is probably the best and most user friendly app I've found for creating and modifying documents. Once I discovered how to save over the original (rather than saving as a copy all the time), things became easier. I have tried the other apps that do the same thing and have found them awkward. If you just open up your documents within the app, editing is very easy.
Tips for using the product
The Polaris office will help a lot of people to save things that they don't want to forget or write projects and than print them for their daily life in school or in work.
