Verdict
The clearest difference is update cadence: Rythm Health at every 3 days against Athos's monthly. Rythm Health also leads on ratings volume (40 vs 1) and chart position (#52 vs unranked). Athos's advantage is rating (5.0 vs 4.6). On price, ads, in-app purchases and monetization model there is nothing between them.
