During Macworld | iWorld 2012 last week, I had the opportunity to meet with Denys Zhadanov of Readdle. If you're not familiar with Readdle's products, you might be new to the iOS world. The company has been around for four years and has sold over 3.5 million iOS apps, most of them used for reading and annotating PDF files.
The company's newest entry into this market should be hitting the App Store any day now. Called Remarks, the app will sell for US$4.99 and is used to open, edit, and then save and distribute PDF files. My favorite part of the demonstration was when Denys opened a magazine file, tapped several pages, and created a new PDF file with annotations within seconds. Remarks has some unique navigation tools for precisely locating text or handwritten annotations, and it can save in either regular (layered) or flattened PDF formats.
A short video showing off the impressive feature set of Remarks is embedded below.
