# AB Quantum vs SubMOA

The clearest difference is rating: AB Quantum at 4.7 against SubMOA's 3.1. AB Quantum also leads on ratings volume (2.7K vs 48) and chart position (#130 vs unranked). SubMOA's advantage is in-app purchases (none vs 15) and iOS requirement (14.0 vs 16.0). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. AB Quantum sells 15 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 2.7K 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 50% 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 September 23, 2026 and September 9, 2026 respectively.
