Notability, one of the more popular handwriting and note taking apps, has just been updated to version 5.0 which brings with it support for iPhone. Previously Notability was only available for iPad. The update also brings iCloud sync so your notes will be available to you regardless what iOS device you're on.
Outside of offering the ability to take handwritten notes, Notability lets users type notes, annotate documents, sign contracts, and more. Since it's one of the more popular note taking apps, it's also one of the most widely supported by third party developers.
Whether you're a student or a professional, Notability is a great productivity tool and with iPhone support now included at no additional charge, it makes it an even more viable option for many. If you pick it up, let us know what you think of the update.
