Verdict

The call

The clearest difference is in-app purchases: Lapua Ballistics at none against AB Quantum's 15. Lapua Ballistics also leads on review sentiment (67% vs 45%). AB Quantum's advantage is update cadence (fortnightly vs every 6 months) and ratings volume (2.9K vs 10). On price, ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

AB Quantum holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: AB Quantum has 2.9K ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 45% of AB Quantum's written reviews are positive against 67% of Lapua Ballistics's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

AB Quantum ships an update fortnightly, Lapua Ballistics every 6 months. The most recent releases landed on October 21, 2026 and October 7, 2026 respectively.
