Verdict

The call

The clearest difference is ads: CodeArt at none against RubySketch's shown. CodeArt also leads on update cadence (every 5 days vs every 5 weeks) and monetization model (free vs free with in-app purchases). RubySketch's advantage is ratings volume (24 vs 7) and iOS requirement (16.0 vs 18.4). On price, in-app purchases and device support there is nothing between them.
