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.
