||Circus Ponies NoteBook is the best app for taking notes on iPad.
Note-taking with all the flexibility of paper, and then some. Take notes using a full-featured outliner, multi-font text, even attachments. Build diagrams from shapes and lines. Create sketches with your fingers.
Never miss a detail from a meeting or lecture with voice-annotated notes. NoteBook records the person speaking as you type your notes, and can start playback from any note you typed. Review the recording at a later date and fill in anything you missed.
Annotate class notes and other PDFs. Insert PDFs as separate pages in your Notebook, then apply shapes, sketches and text notes to mark-up them up. A great way to take notes in class!
Keep notes organized your way, not as lists of notes. NoteBook's natural “notebook” interface keeps your notes organized using pages, sections and subsections, just as you would with a paper notebook.
Find anything instantly. NoteBook’s patented Multidex helps you locate your notes by what little you remember about them: a name, a number, the date you entered them. Find any note with just a few taps.
Access your Notebooks on the go, or on your desk. Work with your Notebooks on your iPad, then pick up where you left off on your Mac using the Mac version of NoteBook.
