Really well done!

Great line stabilisation.
Exceptional text and bubble tools (though there’s still room for improvement in terms of style options)
Very well thought out, easy to use perspective tools.
This is the surprising part though - incredible pencil tools and drawing feel. I’m a huge fan of another big iPad only art app, but it’s a shame more people aren’t trying Comicdraw, as its core drawing tools are surprisingly great. It works well as a digital sketchbook even if you don’t use it for comic creation. I choose to ink in CD over everything else.
About the only major missing features I’d love are the ability to save out PSDs with the text layers staying editable. (I suspect this is difficult or impossible to implement though?) It exports the bubbles and the text as a single pixel layer, which is fine, but editable text layers in PSDs would give it some great interoperability with other apps and would future-proof all of our files should we need to switch platforms or something at a later date.
The other feature has been mentioned in other reviews. Masking/clipping inside panels would make things a bit easier to work with, but it’s okay to work around.
Easily one of the best art apps on iPad, and criminally under appreciated. As a comic production app it’s streamlined and well thought out, I've not used anything that nails the balance between power and ease of use this well. Great job!
