Verdict
The clearest difference is ads: Learn Ruby Fast at none against RubySketch's shown. Learn Ruby Fast also leads on rating (5.0 vs 4.7). RubySketch's advantage is update cadence (every 5 weeks vs every 6 months) and ratings volume (24 vs 3). On price, review sentiment, in-app purchases and monetization model there is nothing between them.
