For the last 2 years I have been using Ibis Paint for my digital art. But now that I am diving deep into the HighRise creator world it seems that Illustrator definitely makes creating concepts and such with the HR aesthetic and style much easier with the shape, shading, etc. options.
However, I am currently on a super tight budget so I am wondering if y’all have any suggestions for a free vector art app that compares to illustrator for android and windows. Thanks in advance!
you can use clip studio paint for mobile or laptop its more effective than ibis paint.
Heard thank you so much !! 
its fine for the cracked version for Laptops or PC’s You can download from Getintopc.com ,for mobile ipads its free
I actually will just find a link or download via app stores on my devices thanks though!
infinite design and sketchbook is good for illustrator?
Not too sure whether you’re drawing on a tablet or not but i really like using MediBang Paint, and zooming in so I can draw in pixelized form, and then zoom out to see how it would look in HR.
