# AB Quantum vs BagMath

The clearest difference is in-app purchases: BagMath at none against AB Quantum's 15. BagMath also leads on rating (5.0 vs 4.7). AB Quantum's advantage is ratings volume (2.7K vs 1) and chart position (#103 vs unranked). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. AB Quantum sells 15 in-app purchases, starting at $2.99 per month. BagMath asks for nothing beyond the download.

BagMath holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: AB Quantum has 2.7K ratings behind it against 1, so its average is the more settled of the two.

AB Quantum ships an update fortnightly, BagMath every 2 weeks. The most recent releases landed on October 9, 2026 and September 28, 2026 respectively.
