## What is AB Quantum?

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.

### 5/5 — Nothing better

*2026-08-22, version 3.7.4*

This app is for serious people who need accurate information to to engage targets longer than 500 yards

### 5/5 — Best Ballistics App

*2026-08-19, version 3.7.4*

This is without a doubt the best ballistics app I have ever used. I’ve tried several others and they don’t come close to the depth and breadth of this app.

### 1/5 — Crash Again

*2026-08-13, version 3.7.4*

After the latest update is still crashing.

Here are the steps to reproduce the crash:

1. Synchronize with the Bluetooth device (Kestrel WEZ).

2. Go to the Devices page.

3. Swipe up and force close AB Quantum from iOS ( try 2-3 times).

4. Open AB Quantum again.

The app will not load. It just stuck on the AB Quantum startup screen.

The latest update did not fix this issue. Please have the development team check it again.

### 4/5 — Athlon Rangecraft and Apple Watch Support?

*2026-08-10, version 3.7.4*

Love this app, some great features. But it would be nice if there was connectivity with the increasingly popular Athlon Rangecraft chronograph. And Apple Watch support for DOPE cards to be displayed. Otherwise a great app for PRS.

### 5/5 — 1 Ballistic Solver in the field

*2026-08-09, version 3.7.4*

Pair this with the kestrel and the solutions it spits out are spot on. Yes it costs more than others.  I have some of the others also and do compare them side by side. Input with same data. Every time AB is the most consistent and reliable. With every caliber.

### 1/5 — Bad app

*2026-08-08, version 3.7.4*

It's always something, sometimes the app won't open for weeks, paying for a membership for nothing is always a problem with the app

### 5/5 — Traduction Française est t’il possible ?

*2026-07-31, version 3.7.3*

Très bonne application ! Est t’il possible de faire une langue française qu’on pourrait changer dans les paramètres comme dans les autres calculateurs balistiques ? Merci cordialement

### 5/5 — Easy to use

*2026-07-29, version 3.7.3*

Just started using it and so far I like it.

### 5/5 — Great application

*2026-07-19, version 3.7.3*

I’m a Strellock convertee. Just discovered there is a lock button for wind input. Couldn’t understand why it wouldn’t change.

### 5/5 — Ab quantum

*2026-07-08, version 3.7.3*

The best there is just set it up right and it will never let you down
