ReceptionRating · Positive reviews · Number of ratings

Pair Cale holds the better App Store score, 4.0 against 3.1. That said, the two scores are not equally well evidenced: My Dog Has Fleas! has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 64% of My Dog Has Fleas!'s written reviews are positive against 31% of Pair Cale's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

My Dog Has Fleas! ships an update every 24 months, Pair Cale every 5 days. Both last shipped on November 6, 2026.
