Verdict
The clearest difference is rating: AB Quantum at 4.7 against SubMOA's 3.1. AB Quantum also leads on ratings volume (3K vs 48) and chart position (#109 vs unranked). SubMOA's advantage is in-app purchases (none vs 4) and iOS requirement (14.0 vs 16.0). On price, review sentiment, update cadence and ads 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. AB Quantum sells 4 in-app purchases, starting at $2.99 per month. SubMOA asks for nothing beyond the download.
AB Quantum holds the better App Store score, 4.7 against 3.1. That said, the two scores are not equally well evidenced: AB Quantum has 3K ratings behind it against 48, so its average is the more settled of the two. Written reviews complicate that: 45% of AB Quantum's written reviews are positive against 46% of SubMOA's, so the app with the better star average is not the one people write more warmly about.
AB Quantum ships an update fortnightly, SubMOA monthly. The most recent releases landed on November 11, 2026 and November 1, 2026 respectively.
