Applied Ballistics Quantum™ is a state-of-the-art app integrating the most complete ballistics solver and profile management tool for long-range shooting. 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.
PRS Shot Timer
Read full descriptionHide full description
PRS Shot Timer is a par timer and shot timer built for precision rifle shooters. PRS and NRL stages run on the clock, so this app puts that clock in your pocket and lets you practice stages exactly the way you shoot them. PAR TIME STAGES Set your stage par time, hit start, and run it. Audible start beep and end-of-par signal, so you learn what 90 or 120 seconds actually feels like from behind the rifle. SHOT DETECTION AND SPLITS The timer picks up your shots and records the time of each one, giving you your splits and total time. See where you are losing seconds: the first shot, the transitions, or the position changes. POSITIONAL DRILLS Build drills around the positions you actually shoot. Barricades, tripods, tank traps, rooftops and awkward props. Set a par, run the position, and track whether you are getting faster. DRY FIRE PRACTICE Run par times in dry fire at home. Position building, bolt manipulation, and transitions cost nothing to practice and are where most stage time is won. SESSION LOG Every run is saved. Review your times, compare drills, and watch your progress across a season instead of guessing. BUILT FOR RIFLE Designed around centerfire and rimfire rifle shooting rather than pistol, including the realities of muzzle brakes and suppressors on the line. METRIC AND IMPERIAL Full unit support wherever you shoot. FREE No ads. Core features free. PRS Shot Timer is a practice and timing tool for organised, safe competitive shooting. Always follow range commands and safe firearm handling practices.

Verdict
The clearest difference is in-app purchases: PRS Shot Timer at none against AB Quantum's 15. PRS Shot Timer also leads on update cadence (every 3 days vs fortnightly) and device support (4 vs 2). AB Quantum's advantage is chart position (#106 vs unranked). On price, ads and iOS requirement there is nothing between them.
