ReceptionRating · Positive reviews · Number of ratings

Aluminum Quick Reference holds the better App Store score, 5.0 against 4.6.

Written reviews complicate that: 0% of Aluminum Quick Reference's written reviews are positive against 81% of ListenBook Pro's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Aluminum Quick Reference ships an update every 7 months, ListenBook Pro every 3 weeks. The most recent releases landed on October 24, 2026 and October 29, 2026 respectively.
