# AB Quantum vs Eagle Ballistics

AB Quantum and Eagle Ballistics both sit at 4.7 stars, but that hides the real split: 75% of Eagle Ballistics's written reviews are positive against 45% of AB Quantum's. AB Quantum's advantage is ratings volume (2.9K vs 30) and chart position (#99 vs unranked). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. AB Quantum sells 4 in-app purchases, starting at $2.99 per month and Eagle Ballistics sells 10 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for AB Quantum against 4.8 for Eagle Ballistics. That said, the two scores are not equally well evidenced: AB Quantum has 2.9K ratings behind it against 30, so its average is the more settled of the two. Written reviews are what separate them: 45% of AB Quantum's written reviews are positive against 75% of Eagle Ballistics's.

AB Quantum ships an update fortnightly, Eagle Ballistics monthly. The most recent releases landed on November 1, 2026 and October 30, 2026 respectively.
