Recorder is this magic pen that converts your written notes into electronic files and then transfers it to your phone and computer via Bluetooth. I think it’s a great idea and can actually encourage us writers to take to the book and pen more often. I bet authors and illustrators will love it too! My only wish – it auto spellchecks the files.USB dongle is for storing your writing when you don't have a Bluetooth computer nearby? If it only worked when you were next to your laptop that would be a major pain!
