The call

The clearest difference is rating: HB Auditory Memory at 3.6 against Sentence Constructor's 1.0. HB Auditory Memory also leads on in-app purchases (none vs 1) and ratings volume (35 vs 1). Sentence Constructor's advantage is review sentiment (100% vs 64%) and iOS requirement (8.1 vs 15.0). On price, update cadence, ads and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

HB Auditory Memory holds the better App Store score, 3.6 against 1.0. That said, the two scores are not equally well evidenced: HB Auditory Memory has 35 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 64% of HB Auditory Memory's written reviews are positive against 100% of Sentence Constructor's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

HB Auditory Memory ships an update every 3 months, Sentence Constructor every 4 months. The most recent releases landed on October 16, 2026 and September 28, 2026 respectively.
