Verdict

The call

The clearest difference is price: Math Kids at Free against Kid Calculator's $0.99. Math Kids also leads on rating (4.5 vs 3.5) and update cadence (fortnightly vs every 13 months). Kid Calculator's advantage is iOS requirement (10.0 vs 15.0). On review sentiment, ads, in-app purchases and device support there is nothing between them.

Math Kids is free to download; Kid Calculator costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

Math Kids holds the better App Store score, 4.5 against 3.5. That said, the two scores are not equally well evidenced: Math Kids has 10K ratings behind it against 18, so its average is the more settled of the two. Written reviews complicate that: 86% of Kid Calculator's written reviews are positive against 83% of Math Kids's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Kid Calculator ships an update every 13 months, Math Kids fortnightly. The most recent releases landed on November 2, 2026 and November 13, 2026 respectively.
