ReceptionRating · Positive reviews · Number of ratings

Sololearn holds the better App Store score, 4.8 against 3.9. That said, the two scores are not equally well evidenced: Sololearn has 82K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 70% of Sololearn's written reviews are positive against 92% of Mental Arithmetic For Learn's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Sololearn ships an update every 2 weeks, Mental Arithmetic For Learn every 3 days. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
