Notability

==Notability is the best-selling note-taking app on iPad. Notability is so powerful that it will transform how you study: sketch ideas, annotate documents, keep a journal, jot travel notes, make a presentation and much more.==

==Import forms, contracts, worksheets, documents, presentations, and even books; then use the same tools that help you take beautiful notes in Notability to mark up PDFs. Do you have files in other formats such as doc or ppt? Notability can import these too thanks to Google Drive.==
