# AB Quantum vs Leica 2Hunt

The clearest difference is review sentiment: Leica 2Hunt at 100% against AB Quantum's 45%. Leica 2Hunt also leads on in-app purchases (none vs 15). AB Quantum's advantage is rating (4.7 vs 3.6) and ratings volume (2.9K vs 10). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. AB Quantum sells 15 in-app purchases, starting at $2.99 per month. Leica 2Hunt asks for nothing beyond the download.

AB Quantum holds the better App Store score, 4.7 against 3.6. 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 100% of Leica 2Hunt's, so the app with the better star average is not the one people write more warmly about.

AB Quantum ships an update fortnightly, Leica 2Hunt every 6 weeks. The most recent releases landed on October 23, 2026 and October 22, 2026 respectively.
