ReceptionRating · Positive reviews · Number of ratings

Sadlier Reader holds the better App Store score, 3.7 against 2.1. That said, the two scores are not equally well evidenced: HMH Go has 71 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 22% of HMH Go's written reviews are positive against 0% of Sadlier Reader's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

HMH Go ships an update every 4 months, Sadlier Reader every 25 months. The most recent releases landed on October 17, 2026 and October 10, 2026 respectively.
