Verdict
The clearest difference is ratings volume: MyZio at 69K against Carium Care's 7. MyZio also leads on chart position (#34 vs unranked). Carium Care's advantage is update cadence (every 6 weeks vs every 6 months) and rating (5.0 vs 4.8). On price, ads, in-app purchases and monetization model there is nothing between them.
