Verdict
The clearest difference is update cadence: IQ2 at fortnightly against Memory Chomp's every 2 months. IQ2 also leads on ratings volume (4.6K vs 788) and iOS requirement (9.0 vs 15.0). Memory Chomp's advantage is review sentiment (100% vs 87%). On price, rating, ads 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. Neither carries in-app purchases, so what you see is what you pay.
IQ2 holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: IQ2 has 4.6K ratings behind it against 788, so its average is the more settled of the two. Written reviews complicate that: 87% of IQ2's written reviews are positive against 100% of Memory Chomp's, so the app with the better star average is not the one people write more warmly about.
IQ2 ships an update fortnightly, Memory Chomp every 2 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
