GeoBallistics

Review by eFreeware

Most shooting apps do one job. GeoBallistics tries to fold three into one: a ballistics calculator, atmospheric data and a GPS rangefinder, all in a single Android app. That combination is the reason it stands out, and it is also the thing that decides whether it belongs on your phone.

It is built for precision rifle shooters who work from a known position and need a firing solution rather than a score. If you already carry a separate rangefinder, a weather meter and a solver, this app is an argument for consolidating them. If you shoot casually at fixed distances, the depth here is more than you need.

The app is free to install and supported by ads, with in-app purchases that unlock a PRO tier. It has been available since April 2016 and has passed 100,000 installs, holding a 3.4 average across 511 ratings. That is a middling score for a tool this technical, and it is worth understanding what the free tier covers before you commit to it as your main solver.

What the BallisticsARC solver actually does

The engine underneath is the BallisticsARC solver, which the developer describes as an advanced 3 DOF model. In plain terms, it accounts for the factors that push a bullet off the line you intended: muzzle velocity changes with temperature, the Coriolis effect, gyroscopic spin drift and crosswind jump.

For a shooter, the practical consequence is that solutions are not a simple drop table. The app also handles moving targets, multiple targets at different azimuths and angles, and shot angle and shot bearing calculations. Muzzle velocity truing is included, so you can adjust the model to match what your rifle actually does rather than what a box label claims.

Coriolis is calculated automatically from your position and latitude, which removes a step that some solvers leave to the user. There is also a comprehensive bullet library built in, so you are not starting from a blank profile every time you change ammunition.

Four modes and how they differ

All four modes are available with a single custom rifle profile, which is the free tier's main constraint.

HUD Mode puts a single target's solution on one screen and is where the moving target feature and the max ordinate display live. Chart Mode is the traditional calculator view, producing a complete solution that takes in gyroscopic drift, Coriolis, wind, shot angle and atmospheric conditions. It is also where WeatherFlow hardware integration is available at no cost.

Map Mode is the rangefinding side. You drop pins on satellite imagery of a shooting location, and tapping a pin returns range and solution. It also layers external ballistic data over the imagery, showing how a bullet performs along its path according to the parameters set for each rifle profile.

Comp Mode is for competition stages. Targets within a course of fire can each carry a separate angle and azimuth. It now includes the Holdover Data Zero calculator, a feature the developer pitches as first-in-class for setting an optimal zero for holdover stages.

Hardware and data integration

Rangefinding hardware such as the Vortex Razor HD 4000 GB and Vortex Relay feeds the same workflow as the solver. That matters if you already own that glass, because it keeps the distance reading and the firing solution in one place.

Weather hardware support is split. WeatherFlow products integrate free, and the app can pull online weather with station pressure. Kestrel LiNK compatibility sits behind the PRO upgrade, so shooters invested in that ecosystem should factor the cost in.

There is also online backup for rifles and range cards, along with match and shooting range downloads. Those backup features are part of the PRO tier, which is worth noting if you like the idea of keeping profiles synchronized rather than rebuilding them.

What PRO changes

The free app gives you all four modes with one custom rifle. Everything beyond that single profile runs through the PRO upgrade, which the developer sells as a one-time fee rather than a recurring subscription.

PRO covers unlimited rifle profiles, saving and loading satellite range cards for later use, saving charts to your camera roll and exporting them as .csv. It also unlocks Kestrel device support, online rifle and range card backup, and the match and range downloads.

For a shooter with one rifle and one load, the free tier may be enough to be useful. For anyone running several rifles, or wanting a record of past sessions, the upgrade is effectively the price of admission. Ads are a further consideration if you prefer an uncluttered screen at the range.

The trade-offs to weigh

The clearest limit is the single rifle profile on the free tier. A precision shooter rarely stops at one, so the free version functions more as a trial of the solver than as a permanent setup.

Kestrel LiNK hardware compatibility and the export and backup features are also gated behind PRO. If your workflow depends on moving data out of the app or syncing it between devices, that shapes the real cost of using GeoBallistics.

The 3.4 average across 511 ratings suggests a mixed reception, though ratings alone say little about how a specialized tool performs for the people it is designed for. Ads and in-app purchases are part of the free experience.

Who gets the most from it

This is a tool for shooters who already think in terms of atmospherics, spin drift and shot angle. If you know what muzzle velocity truing is and why Coriolis matters at distance, the depth here is likely to feel appropriate rather than excessive.

It suits people who want the solver, the weather input and the map-based ranging on one screen, especially those using Vortex Razor HD 4000 GB or Vortex Relay hardware. Competition shooters working holdover stages have a dedicated mode with the HDZ calculator.

It is less compelling for someone who wants quick holdovers at known distances, or who prefers a lightweight app. The free tier's single profile and the PRO gate on exports and Kestrel support define who will get comfortable with it and who will find it restrictive.

A serious solver with a paid ceiling

GeoBallistics suits precision rifle shooters who want solutions, atmospherics and GPS ranging in one app. The BallisticsARC solver covers the factors that matter at distance, the four modes map cleanly onto different kinds of shooting, and the Vortex and WeatherFlow integrations keep hardware in the same workflow.

The catch is that the free version is built around a single rifle profile, with unlimited profiles, exports, satellite range card saving, Kestrel support and online backup all sitting behind the one-time PRO fee.

If you shoot one rifle and want a capable solver without paying, this is a reasonable place to start. If you run multiple rifles or need your data to move between devices, budget for the upgrade from the outset. It is a specialized tool, and it rewards the shooter who already speaks its language.
