Evernote does a great job of providing you a way to take take notes and access them anywhere. You can edit them from the app on your phone or from any web browser. Not only can you type out a note, but you can leave voice and picture notes as well. This is super handy especially since there's no native note app for Android (yet). Other nice features are the ability to tag your content, organize it in folders, share with others , and save searches. It feels pretty lightweight and is very easy to use. I definitely recommend this app.
