Verdict
The clearest difference is ads: Chess Studio at none against Epub Reader's shown. Chess Studio also leads on iOS requirement (9.0 vs 15.0). Epub Reader's advantage is update cadence (every 11 days vs every 2 months) and chart position (#130 vs unranked). On price, review sentiment, in-app purchases and monetization model there is nothing between them.
