The app looks nice. But when using it you can see that it does not record voice (notability does) and you cant take a picture from the app itself (notability can do this too). If you are buying this because of the mac integration, then it is a good idea. Be aware that you will note be able to have these advantages. By the time you are reading this, you might as well check in the mac app store if notability has an app for the mac and it would be a much better purchase... Or you could send an email to the people from notability to move then forward in making a mac app. I wouldnt say the app is bad, but you would expect that for the price paid you would receive much more. Course note developers, keep on going... There is still a LOOOOOOONG way to go but you are in the right direction.
