Verdict

The call

The clearest difference is rating: CDC at 2.9 against Vaccine Tracker's 1.7. CDC also leads on ratings volume (413 vs 3) and review sentiment (22% vs 0%). Vaccine Tracker's advantage is update cadence (daily vs monthly) and iOS requirement (8.0 vs 15.6). On price, ads, in-app purchases and monetization model there is nothing between them.
