One of the few things from Windows that I have missed since moving to my Mac was Microsoft’s One Note. Evernote attempted to fill the gap, and syncing notes with my mobile devices was a nice feature. But, it wasn’t the same. Growly Notes is the closest alternative to One Note on the Mac that I have found, and it’s free. If you loved using One Note you should definitely give this app a try.
You can download Growly Notes for free here.
