ReceptionRating · Positive reviews · Number of ratings

Half Marathon 13.1 Trainer holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Half Marathon 13.1 Trainer has 5.6K ratings behind it against 119, so its average is the more settled of the two. Written reviews complicate that: 56% of Half Marathon 13.1 Trainer's written reviews are positive against 71% of Run Half Marathon's, so the app with the better star average is not the one people write more warmly about.
