2025 Lapua Ballistics App Updates
Lapua has added some significant 2025 updates to its Ballistics App. New features include:
Range Presets: Create ranges, with angles, and quickly move between them. Output Units: Set the unit of the calculation output to clicks, MRAD, or MOA Device Compass for Shooting Direction: When getting wind data or getting location in Coriolis tab, shooting direction is taken from device compass. Wind Direction Correction: When changing shooting direction, ether by Coriolis tab or Get wind data button, wind direction is corrected by the new shooting direction.

Hornady has released a new FREE Ballistic Calculator App for iOS (Apple) and Android OS. This new Mobile Ballistic App includes Hornady’s advanced 4DOF™ calculator as well as a standard BC (ballistic coefficient) calculator. The Hornady Ballistic Calculator App is Bluetooth-enabled so it can communicate with select wind meters.
The Hornady Ballistic App is FREE but you do need to supply an email address. We found the App downloaded quickly and installed easily. While the Mobile Ballistic App is new, Hornady has offered a web-based online 4DOF Ballistic App since August 2016.
Hornady’s new 4DOF™ (4 Degrees of Freedom) Ballistic Calculator has become a popular resource for those seeking more accurate trajectories, especially at extreme ranges. The Hornady 4DOF calculator provides trajectory solutions based on projectile Drag Coefficient (not ballistic coefficient) along with the exact physical modeling of the projectile and its mass and aerodynamic properties. Additionally, it is the first publicly-available program that will correctly calculate the vertical shift a bullet experiences as it encounters a crosswind; referred to as aerodynamic jump. Hornady claims that: “The use of drag coefficients, correct projectile dynamics, aerodynamic jump, and spin drift enable the Hornady 4DOF ballistic calculator to be the most accurate commercial trajectory program available[.]”
“Current ballistic calculators provide three degrees of freedom in their approach; windage, elevation and range, but treat the projectile as an inanimate lump flying through the air,” said Dave Emary, Hornady Chief Ballistician. “This program incorporates the projectile’s movement in the standard three degrees but also adds its movement about its center of gravity and subsequent angle relative to its line of flight, which is the fourth degree of freedom.”
Bullet Drag Profiles Created with Doppler Radar
Using Doppler radar, Hornady engineers have calculated exact drag versus velocity curves for each bullet in the 4DOF™ calculator library. Hornady engineers say this makes the 4DOF™ calculator “more accurate for long range hits than … BC-based systems or custom drag curves based on limited data collection points.”
The 4DOF ballistic calculator is used with pre-populated bullet files that include long range match and hunting style bullets from Hornady including ELD-X and ELD Match bullets. In addition, popular long range projectiles from Sierra, Berger, and other bullet-makers are included. To view the web-based version of 4DOF and see the projectiles available, visit www.Hornady.com/4dof.
Standard Ballistics Calculator Functionality
The new Hornady Mobile App also features a standard BC-based calculator for use with bullets not listed in the 4DOF database. Users can enter their own G1 or G7 BC, or choose from the entire lineup of Hornady bullets and ammunition in easily-filtered, pre-populated lists.
Installation and User Feedback
We installed Hornady’s new Mobile Ballistic App on an Apple iPhone 5s and and older Samsung Galaxy. The App downloaded quickly and installed flawlessly on both platforms. We were able to register easily (once we added a Capital Letter to the password) and the App launched without a hitch. This Hornady App is FREE but it does require users to submit an email address. This enables Hornady to send marketing messages, but registered users may opt out.
NOTE: A couple iOS and Android users reported issues with registration. This might be a software bug (or, more likely, it was user error) but we thought we should report this:
From Apple App Store Reviews:
“Tried registration, failed on the App and it won’t take my site info.” — Heavy G 603
“App crashes right after the two accept buttons.” — Austin.M
From Google Play Reviews:
“Required registration works on website but not for this app…” — Ken S., 11/2/17
