ReceptionRating · Positive reviews · Number of ratings

ReDi holds the better App Store score, 4.5 against 3.6. That said, the two scores are not equally well evidenced: ReDi has 281 ratings behind it against 35, 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 57% of ReDi'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, ReDi every 6 days. The most recent releases landed on September 27, 2026 and October 12, 2026 respectively.
