## What is Reactor (Official)?

Reactor's mobile app pairs with the Reactor Fusion Module to automate your data books and provide valuable insights into your shooting. It brings similar benefits as a fitness tracking app to the marksmanship world, allowing you to spend more time focused on your shooting and less time writing with pen and paper.

The app shows summaries of your shots, sets, weather information, and displays metrics for each rifle component for knowing when it's time to perform maintenance on your rifle.

The real-time heads-up display helps you learn more about how you cant your rifle when you shoot, how barrel temperature affects your shots, and shows quick-access weather information. All of this information is automatically logged to your account when shots take place.

Reactor NEVER logs this information without your Fusion Module being on and paired, and we have completely transparent business practices to ensure your privacy and rights as a gun owner are protected. If you have questions, please contact us at https://reactorusa.com/contact

### 5/5 — Easy to use UI and revolutionary features and functionality.

*2020-05-30*

This is the the most advanced rifle intelligence system ever created. The shot counting feature is brilliant. Completely passive, running in the background without any effort from the shooter. The system will even start a set even if you forgot to start it manually. It understands when a shot is fired and will track it even if you forget to begin the set. 

There are so many features that come along side the shot once detected. Weather data, rifle orientation, barrel temperature, gps location and more. Everything is logged and stored for you without you having to do anything. 

The Heads Up Display (HUD) gives you real time information about the orientation, barrel temp, weather data and more of your rifle.  This is so useful when attempting to dissect an upcoming, complex shot. All this information can be used to input useful data into your ballistic calculator. 

This product is truly revolutionary and adds incredible value to the shooter and insight on each shot and set of shots.  This is the biggest leap in firearms technology the industry has ever seen.
