ReceptionRating · Positive reviews · Number of ratings

einstein Junior holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: STEM Buddies has 40 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of einstein Junior's written reviews are positive against 100% of STEM Buddies's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

einstein Junior ships an update every 24 months, STEM Buddies every 5 months. The most recent releases landed on October 11, 2026 and October 12, 2026 respectively.
