Verdict
The clearest difference is review sentiment: Fable Frog at 50% against Comma Reading App's 0%. Fable Frog also leads on update cadence (every 6 days vs fortnightly) and iOS requirement (17.0 vs 26.6). Comma Reading App's advantage is monetization model (free vs free with in-app purchases). On price, ads, in-app purchases and device support there is nothing between them.
