About

A ballstics app that shows red dot and holographic overlay along with the MIL calculation for windage and elevation. The application has a config to overlay 1 dot, 2 dots, and 4 dots - a christmas tree mil dot. You can change your ring to match your reticle, but defaults to 68 MOA. The dots are identical to the most popular 4 dot holographic (holographic BDC for a 62 Gr. M855 FMJ round at approximately 2,680 fps - 300, 400, 500, and 600 yrds). The 2 dot similarly follows the most popular 2 dot holographic sight (bdc for 200 and 500 yrds). The application uses G1 external ballistics and uses the onboard watch sensors for atmospheric conditions. The app allows for saving 4 different rifle/bullet profiles. *1 Handed operation through gestures!* - keep one hand on your rilfe and adjust calculation! Twist your wrist forward to add 25yrds to the calculated distance, and flap your wrist from 12 o'clock to 3 o'clock to add 100yrds to the calculated distance (point to the sky and then point to the horizon in a fast motion). Feel free to reach out if you find yourself wishing the app had something! Check out my companion app - the game version! Note: you likely want to remove the default settings menu for holding down or up, as that can make some weird interactions.
