This handwriting app for your iPad remains the most powerful and fully-featured option around. Now you can create as many notebooks as you want with an infinite number of pages in each, and classify these by topic, project or category. Notebooks can be presented as a carousel, or your can scroll through them using a grid view. Within each binder, you can also delete, duplicate and reorganize pages as you see fit, even between two different notebooks. And when you’ve finalized the notes you took down, you can print or email them.
