Verdict
The clearest difference is rating: One Markdown at 4.6 against MD Flow's 1.0. One Markdown also leads on ratings volume (141 vs 1) and iOS requirement (14.5 vs 17.0). MD Flow's advantage is monetization model (free vs free with in-app purchases) and update cadence (every 9 days vs monthly). On price, ads, in-app purchases and device support there is nothing between them.
