A note on the use of these calculators. While they are as mathematically correct as is practical, they are, as the heading suggests, simple. They are designed to port to a mobile so you can chill out and send stuff down range without having to think too much.
They are not designed to be an all bells and whistles ballistic computational wonder that takes into account projectile weights and drag coefficients. No atmospherics or Coriolis effect and they don’t even take into account the fact that the Earth wobbles on it’s axis one degree every 72 years. Scroll down for a link to Ballistic Calculators.
