SmileOnMyMac has updated PDFpen adding the ability to sync with Dropbox folders for sharing files between multiple devices. An iOS adaptation of the company’s popular PDF annotation and editing software for Mac OS X, PDFpen brings an advanced set of PDF editing features to the iPad such as the ability to add text, images, signatures, comments and annotations to PDF documents, make changes to existing editable text blocks and images and fill out PDF forms. Users can also e-mail documents out directly from the device or save them to Dropbox, Evernote or Google Docs or synchronize documents between multiple iPads and PDFpen for OS X. Version 1.2 adds Dropbox syncing as an alternative to iCloud and allows users to create a document from selected pages or a photo. The update also adds French, German, Italian, Spanish, Japanese and Chinese localizations. PDFpen for iPad requires iOS 5.0 or later and is available from the App Store for $15.
