Verdict
The clearest difference is rating: Learn Abacus at 4.5 against KIDS SUM's 3.8. Learn Abacus also leads on in-app purchases (none vs 3) and update cadence (every 3 weeks vs every 2 months). KIDS SUM's advantage is ratings volume (83 vs 2) and iOS requirement (12.0 vs 15.0). On price, review sentiment, ads and device support 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. KIDS SUM sells 3 in-app purchases, starting at $9.99 per month. Learn Abacus asks for nothing beyond the download.
Learn Abacus holds the better App Store score, 4.5 against 3.8. That said, the two scores are not equally well evidenced: KIDS SUM has 83 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 31% of KIDS SUM's written reviews are positive against 25% of Learn Abacus's, so the app with the better star average is not the one people write more warmly about.
KIDS SUM ships an update every 2 months, Learn Abacus every 3 weeks. The most recent releases landed on October 23, 2026 and October 11, 2026 respectively.
