Ballistic calculator for iPhone, iPad, iPod


Supports iPhone, iPad and iPod (iOS versions from 6.0)

This is a smart ballistic calculator. It can use G1, G7 and... custom drag-functions!
Can calculate trajectory without using ballistic coefficient!

Can calculate spin drift, Coriolis effect, gyroscopic stability factor and vertical deflection of crosswind.

1184 bullets database + 411 bullets with G7 ballistic coefficients
2997 cartridges database

You can select reticle from the list (972 reticles!) and see holdovers (see list of reticles supported)

Compatible with the Kestrel DROP Wireless Data Logger and Kestrel 5500 with LiNK

Supports bluetooth connection with Weatherflow WEATHERmeter.

Supports bluetooth connection with Skywatch BL.

Be informed you need iOS device with Bluetooth 4.0 to connect with weather stations (see the list)

Supports imperial and metric units.

FYI: MILs and MRADs - this is the same

Field-proven accuracy since 2007

Q. I have a (Nightforce, Leupold, Bushnell, etc) scope with MilDot Recticle
Is that in your library of recticles? If yes which one would I have to choose and if no is there a chance you could include it in one of your next updates?

A. MilDot - this is standard reticle and it already listed in my program, so you can select from the list reticle with name "MilDot (USMC)" and use it.


Q. What is your definition of "scope height"?

A. Distance between center line of scope and center line of bore. Like here.


Q. Could you try to explain how to use "truing" feature?

A. Suppose, you input muzzle speed as 2648 f/s
Shoot at distance bigger than zero distance. Suppose this is 800 yards. Calculated elevation for this distance is 26 MOA
Find out REAL elevation is needed to hit the target. Suppose this is 27 MOA.
On the trajectory validation screen input Distance as 800 yards and Elevation as 27 MOA
Tap button "Calculate" and speed at which elevation will be equal 27 MOA will be calculated. It this case, it will be 2609 f/s
Tap button "Use this velocity" and this calculated speed will replace your current cartridge speed (2648->2609) and screen will be closed.
On the main screen tap "Calculate" button and you will get calculated elevation which equals REAL elevation and equals 27 MOA
Now you can input any distance and hit the target.
