I do almost all my vector work for DrawKit using Vectornator, have done for over a year now. It's my favourite iPad editing app, so much power behind such a made-for-touch thoughtful UI 👏
Great UI and functionality, love it :) On a side note, just showing you guys the white space on the landing page link you have here, not sure if its meant to be like that or not! https://app.usebubbles.com/8b526d50-861b-4692-8f9d-66ae56ae73d6
