Readmill first gained attention for its clean ebook reading interface, which lets users highlight and share passages from ebooks without leaving the app. At launch, the app only supported DRM-free EPUB files, limiting it primarily to DRM-free public domain titles. Last October, though, Readmill added support for Adobe DRM and PDFs, opening it up to a much broader range of titles, including those from Kobo, Barnes & Noble and Google Play. (Kindle books still aren’t supported, though, because of Amazon’s proprietary DRM.) Twenty-two independent ebookstores also have a “send to Readmill” feature, so that a user can buy an ebook and immediately sync it to his or her Readmill account.
Readmill’s new iPhone app syncs with the iPad version, so a user can start a book on one device and pick up where he or she left off on another. “We were finding that a growing number of our users wanted to read their ebooks in this way, and the ability to read via a smartphone has been the most requested feature within our existing community to date,” said Readmill cofounder and CEO Henrik Berggren, “so this was a natural next step in development.”
Berggren previously led business development at Berlin-based social music company Soundcloud. Readmill raised its first funding round, an undisclosed amount from Wellington Partners, last June. The company would not disclose how many members it has, saying it’s focusing on user experience for now.
