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.

Score USPSA and IPSC stages in seconds. Keep every run in one logbook. See exactly where the points went. Enter your hits and time in seconds, get the hit factor instantly, save the run, and turn every practice session and match into useful data. FAST, RULE-AWARE SCORING Tap the scoring zones, enter the time, get the hit factor. Track Alphas, Charlies, Deltas, misses, no-shoots, procedurals and steel where the ruleset supports it. Major and Minor power factor are handled automatically for the selected division, and hit factors are calculated to four decimals using truncation rather than rounding. SEVEN SUPPORTED DISCIPLINES Handgun, Rifle, Shotgun, PCC, Mini Rifle, Action Air Handgun and Action Air Rifle, each with its own division list and power-factor logic. MORE THAN A CALCULATOR Every run can be saved, edited and searched. Group runs into matches, separate training from competition, import matches from PractiScore .psc exports, and keep classifier results in the same logbook. Back up your full history to a single readable file whenever you want. SEE WHERE YOUR POINTS GO Turn your logbook into statistics you can act on. Filter by your last 5 runs, last 10 runs, this year, division, matches or training. Track alpha rate, points dropped, penalties, paper and steel performance, your best run in the current filter, and the difference between practice and match shooting. TURN RESULTS INTO DECISIONS Potential shows what a clean run would have scored, and how much slower you could have gone while still matching the hit factor you actually shot. What If lets you change a hit or adjust the time by a tenth of a second and see the effect on hit factor immediately. Test the tradeoff between speed and accuracy before your next run. CLASSIFIERS & STAGE POINTS Compare a run against a reference hit factor, a stage winner, or the level you're chasing. Calculate stage points and percentages, store classifier high hit factors, and see the USPSA classification a classifier result corresponds to. PRIVATE BY DESIGN No account. No sign-up. No analytics. No servers of ours. Your logbook stays on your iPhone and nowhere else. FREE TRIAL AND PURCHASES Everything is unlocked free for the first 7 days. After that, scoring, hit factor, What If and statistics need either a subscription (monthly or yearly) or a one-time 24-hour pass with unlimited use, all billed through your Apple Account. Your logbook is never locked away: your saved runs, export and backups keep working whether you pay or not. Terms of use: https://ipscscoring.com/terms/ Privacy policy: https://ipscscoring.com/privacy-policy/ Spend less time calculating between stages, and more time learning from every run. IPSC Quickscore is back. The original launched years ago as a simple way to calculate hit factor and built a following among practical shooters around the world. After time away from the App Store, version 3.0 is a new beginning for that proven idea — rebuilt from the ground up for the way shooters train and compete today.
