If your phone doesnât have a built-in latitude measurement you will need to enter that manually, but most phones made in the last 2-3 years do have it. Firing azimuth and latitude work together, and are normally called the Coriolis Effect, despite seeming like separate categories on the app.įortunately, each of the above measurements are pulled directly from your phone, so no math is involved. Earth Based Effects is a latitudinal measurement that ties into the amount of centrifugal force imparted on the bullet, which is higher towards the equator and lower towards the poles. Firing Azimuth is a horizontal measurement that comes into play at extreme ranges, and considers the rotation of the earth when determining bullet drop. Shooting Angle measures your gun barrelâs angle relative to level and plays a big part in ballistics. The 4DOF Calculator includes more variables for a more precise adjustment. On the Home Screen, youâll be able to choose between the Standard Ballistics Calculator and their 4DOF Calculator.

The Hornady Ballistics app is great free app that does a good job blending functionality with ease of use. To show how they stack up against each other, weâve made a quick comparison table.įor a more detailed review of each app, read on. Weâve sorted through the good, and not so good, to find the best apps available today. The Apple App store and Google Play store have a wide variety of ballistic calculators to choose from. For extreme precision, measuring the muzzle velocity of the round when fired from your gun would be ideal, but that requires access to a chromometer. Some of the apps have their own database with that measurement included, and others can be found on the manufacturer’s website, but muzzle velocity can vary slightly from gun to gun. Typically, the only other measurement ballistic calculators need is the muzzle velocity of your preferred round. Those functions usually require phones that have built in altimeters and native weather apps. Others will pull that information from your phoneâs sensors and fill it in for you. Some apps are fairly basic, and rely on you to input the needed information before they calculate the necessary sighting adjustments.
Ballistic calculator apps let you streamline the process and cut out the middle man by taking the place of a stand-alone ballistic calculator. These can all affect accuracy and when put into a good ballistic calculator, will help you make more accurate shots. Smartphones can be used to look up weather information specific to your location, such as wind direction, barometric pressure, humidity and temperature. There are many reasons why having a computer in your pocket can come in handy, and accurate long-range shooting is one of them.
