Great PDF
Very easy to use! Updating documents quickly is really helpful and saves me time in my practice. It's great to have the app in case I am not in my office when a change is needed.
There are a few glitches. For example, in order to save a document you have to remember to duplicate it. The emailing feature can be glitchy at times.
