Featuring an all new user-interface, AB Quantum™ includes a host of new tools and features that will enable shooters and hunters to be more successful in the field. AB Quantum™ creates a new paradigm for ballistic solvers and integration with Bluetooth®-enabled devices. With a host of new features, the platform is designed to save time and add performance for users of all skill levels. The all new user-interface is designed with single-handed use in mind, putting all major features just a swipe or tap away from any screen, which allows users to rapidly obtain solutions in the field or at a match. The simplicity and versatility of the app interface creates an intuitive experience for both new and experienced users. Two new features - AB Quantum Connect™ and AB Quantum Sync™ - enable users to quickly connect to other AB-enabled devices and sync gun profiles between them in seconds, as well as back those profiles up to an encrypted server for peace of mind and easy restoration. The new platform automatically saves changes made to rifle profiles and updates connected devices without the user needing to do anything. For competitors or hunters, AB Quantum™ includes customizable Range and Multi-Target tables. This allows users to lay out the displayed information to exactly what they need to hit their target. After creating a range or target card, it can easily be shared via email. Built with the future in mind, the new AB Quantum™ platform allows for continuous innovation. At launch the following new features will be available: • AB Quantum™ User Interface - Take control of ballistic data and find solutions with ease using the new layout designed with one-handed operation in mind. • New Bluetooth® Device Manager - Find and connect AB Bluetooth® devices quickly and send data between devices using AB Quantum Connect™. • AB Quantum Sync™ - User gun profiles are automatically uploaded to an encrypted server to allow easy access for other devices and backup, providing peace of mind and security. • Customizable Range Card and Target Card Modes - The new expandable and customizable range and target card modes allow users to select what data to see for each Range or Target. Use the share function to send range and data cards in just seconds. • New Reticle Library - The AB Reticle library is hosted online and updates in AB Quantum™ automatically, providing users with up-to-date solution drawing for their favorite rifle scopes. • Improved Truing Interface - Easy to access ballistic truing features without leaving solution screens. • Chronograph Integration - Connect Bluetooth®-enabled chronographs - such as the Optex Systems SpeedTracker™ - directly to the app and save the velocity data to rifle profiles.

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
