Verdict
The clearest difference is ads: Mental Math Games at none against kukumber kids's shown. Mental Math Games also leads on ratings volume (1.2K vs 4). kukumber kids's advantage is rating (5.0 vs 4.7) and iOS requirement (16.0 vs 26.0). On price, review sentiment, update cadence and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Mental Math Games sells 7 in-app purchases, starting at $4.99 per month and kukumber kids sells 2 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.
kukumber kids holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Mental Math Games has 1.2K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 93% of Mental Math Games's written reviews are positive against 88% of kukumber kids's, so the app with the better star average is not the one people write more warmly about.
Mental Math Games ships an update every 9 days, kukumber kids weekly. The most recent releases landed on October 25, 2026 and October 19, 2026 respectively.
