ReceptionRating · Positive reviews · Number of ratings

Mystery Math Museum holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: Mystery Math Museum has 314 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 100% of Simplex Spelling Phonics CVC's written reviews are positive against 97% of Mystery Math Museum's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Simplex Spelling Phonics CVC ships an update every 13 months, Mystery Math Museum every 8 months. The most recent releases landed on October 22, 2026 and October 26, 2026 respectively.
