As you can see there are lot of opinions about note taking apps and there are a lot of apps out there. Note taking is such a personal activity that you’ll need to look at what kinds of notes you want to take (typed, handwritten, voice, voice2text) and how you want to organize them and if you want to export them. Almost all of the suggested apps will sync using iCloud or similar services and will give you Mac, iPad, and iPhone versions. You will probably want to try some different ones out. You may want different apps for different purposes. You may want one app for class notes and a different app for research material.I’m starting my PhD and looking for a note taking app for my new iPad Air. And since I’ll also be using my MacBook, I’d like the notes to sync so that it doesn’t matter which device I’m using or have in class.
There are also a lot of message threads around here on note taking and on different notes apps. We are blessed with an abundance of notes apps and most of them are pretty good.
