The main reason I love this app is for the Reflow Text feature for iPhone. Its essential for reading PDFs on a small screen.
I also appreciate its iCloud sync and document organization features, and Crop Mode for iPad. However, the included Web browser is feature-poor, and the fact that I cant export my annotations is a major problem. PDF Expert, from the same company, can export them to HTML, but thats probably not good enough. Id pay for an in-app purchase for genuine export, say to CSV, or the Apple Notes app.
