# RubySketch vs CodeArt

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.

Both are free to download. RubySketch sells 1 one-off in-app purchase and CodeArt sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

CodeArt holds the better App Store score, 4.9 against 4.7. Both are backed by a comparable volume of ratings — 24 and 7 respectively.

RubySketch ships an update every 5 weeks, CodeArt every 5 days. The most recent releases landed on September 21, 2026 and September 24, 2026 respectively.
