Customer Reviews

Best in it's class -- I've tried a few others

This app does everything right, and they have gradually improved and added features. Most important to me is interface with other apps, email, etc. One thing I love to do is transfer emails, texts, articles, memos, documents to the app, and then use the "speak" feature to read them to me while traveling, or just relaxing. For me reading is "work" but listening is effortless, and I retain more from listening. I also like the scan feature, and the ability to have everything available in the PDF format to forward to colleagues and clients. Advice to app'ers (if that's what you're called): keep improving, but balance with keeping it simple. Err on the side of simple and intuitive. AND DONT CHANGE STUFF JUST FOR THE HELL OF IT LIKE MICROSOFT. eg the original version did 90% of what I needed and I learned it in a few hours. Now excel, for example is near incomprehensible, and many features are silly. So what if it theoretically does 95% of what I need, the extra 5% carries a heavy learning curve.

Outstanding App!

Easy to use, feature-packed and user-friendly. What's more to say?

Best app I have used for PDF

This app has done everything I have needed it todo.
