I like Notability and was going to make it my main app for taking notes. However, it is not available for the Mac so there would be no sync between the mac and phone. There are alternative ways of backing up data, but I would prefer to use iCloud.
I really, really like Notability and how you can make dividers and subjects which is great for college . Is there anything like it that is available for Mac and iPhone? My backup notes app is SimpleNote. It doesn't have nearly all the features of the other app and is just limited to tags to organize notes. What other apps have you found?
