Verdict
The clearest difference is rating: CAMMP at 5.0 against Yapp's 3.6. Yapp's advantage is update cadence (fortnightly vs every 5 months) and ratings volume (100 vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.

CAMMP holds the better App Store score, 5.0 against 3.6. That said, the two scores are not equally well evidenced: Yapp has 100 ratings behind it against 3, so its average is the more settled of the two.
