Current technology has given us an option to transfer all information we get from a physical notebook to an electronic one. Below is a list of apps that could be used to write/type notes and organize them.

	OneNote In OneNote, users can create notes that can include text, tables, pictures, and drawings. Unlike a word processor, OneNote features a virtually unbounded document window, in which users can click anywhere on the canvas to create a new text box at that location. Users do not need to explicitly save their work – OneNote saves data automatically as the user works. OneNote saves information in pages organized into sections within notebooks. The interface provides an electronic version of a tabbed ring-binder, into which the user can directly make notes and gather material from other applications. (Wikipedia)
	Notability (iPad only) Combine handwriting, photos and typing in a single note to bring your projects to life. Use a wide range of note-taking and sketching tools to capture every detail. You can even add and annotate PDFs in Notability. It’s the perfect place to create and organize work, school, and life’s information! (Notability)
	Good Notes (iPad only) Note taking app that allows you to search any item in your handwriting, annotate pdfs and PowerPoint presentations, and organize your notes.
