Wait, but watch
This is a novel approach to writing that may not work for many people. The most common gripes people have are that the differences between sections ie Note, Write, Read are somewhat nominal.
There are a number of things iA should do to make this workable for more people. Personally I would love to see more gestures, a dark mode, Dropbox backup (iCloud is good but lets add reliability and extensibility), and third party integration with stuff like Drafts, as well as markdown support and better export.
I ask for all this because its $20
Overall I find its a fresh approach and I look forward to where they go from here.
