# CDC vs Vaccine Tracker

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.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

CDC holds the better App Store score, 2.9 against 1.7. That said, the two scores are not equally well evidenced: CDC has 413 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 22% of CDC's written reviews are positive against 0% of Vaccine Tracker's.

CDC ships an update monthly, Vaccine Tracker daily. The most recent releases landed on October 18, 2026 and October 9, 2026 respectively.
