I have been using both the Laptop, iPad, and iphone versions for 5 years now. I am never disappointed and always amazed at what new things that app can do.

Sure, it's not Adobe Acrobat Pro or PDFpenPro, but super easy and light and more convenient than adobe reader or anything. love it! It's a very good and valued substitute for some applications. Well done!
All the different PDF management tools-conversion, annotation,form filling etc-are as good as advertised and may be even better for how I had hoped. The presentation mode works especially well for me as PDF is the main working format in what I do.
It is intuitive and easy to use. Best application for merging, splitting, shrinking, manipulating, adding and taking away pages with ease. I don't know how I would cope without it. Oh, the free version gets some or most of the simple jobs done.
The program does everything I want in making various notes on the PDF file with highlights, text notes, etc. I grade my students' papers with this app. It's much cleaner than simply scribbling on the paper. Now my students will actually read my feedback for them.
