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
AB Quantum and RaceSync both sit at 4.7 stars, but that hides the real split: 100% of RaceSync's written reviews are positive against 45% of AB Quantum's. RaceSync also leads on in-app purchases (none vs 15) and iOS requirement (14.0 vs 16.0). AB Quantum's advantage is update cadence (fortnightly vs every 3 months) and ratings volume (2.9K vs 53). On price, rating, ads and device support there is nothing between them.
