Ulysses is awesome. I've used it for years on both my Mac and my iPad and it truly is a great app. The one thing that was missing was an iPhone version so I could do quick edits on the go or write while on a plane or somewhere I didn't have access to either Mac or iPad but inspiration struck. I used Deadulus Touch for that, but it wasn't the same.
Then I got an iPad Pro. And while Ulysses for iPad worked great for the most part I did miss split view and the full keyboard.
Well, the guys have just released the new version and it's universal and updated for the iPad Pro.
