Verdict
The clearest difference is rating: One Markdown at 4.6 against Inkiostro's 3.0. One Markdown also leads on review sentiment (82% vs 60%) and ratings volume (141 vs 4). Inkiostro's advantage is update cadence (weekly vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.
