Verdict
The clearest difference is rating: 4=10 at 4.9 against Math Riddles's 4.4. 4=10 also leads on ads (none vs shown) and ratings volume (2.6K vs 5). Math Riddles's advantage is monetization model (free vs free with in-app purchases). 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. 4=10 sells 1 one-off in-app purchase and Math Riddles sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
4=10 holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: 4=10 has 2.6K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 98% of 4=10's written reviews are positive against 100% of Math Riddles's, so the app with the better star average is not the one people write more warmly about.
4=10 ships an update every 2 months, Math Riddles every 6 weeks. The most recent releases landed on October 23, 2026 and October 27, 2026 respectively.
