Verdict
The clearest difference is ratings volume: memoryOS at 17K against AceSolver's 6. memoryOS also leads on rating (4.9 vs 4.7) and chart position (#59 vs unranked). AceSolver's advantage is review sentiment (100% vs 80%) and update cadence (weekly vs every 2 weeks). On price, ads, in-app purchases and monetization model 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. memoryOS sells 23 in-app purchases, starting at $3.99 per 7 days and AceSolver sells 17 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
memoryOS holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: memoryOS has 17K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 80% of memoryOS's written reviews are positive against 100% of AceSolver's, so the app with the better star average is not the one people write more warmly about.
memoryOS ships an update every 2 weeks, AceSolver weekly. Both last shipped on October 25, 2026.
