There are many proven ballistic solvers — Applied Ballistics, Strelok, 4DOF, GeoBallistics, Lapua Ballistics, to name a few — as well as many others. Shooters around the world have good reasons to use and trust them. Beyond mobile applications, some of these solvers are integrated into rangefinders, riflescopes, weather meters, and other platforms, and they perform exceptionally well — until wind comes into play. Unlike temperature, pressure, or distance, wind is highly variable in both space and time. It changes with height above the ground, terrain features, surface roughness, thermal effects, and other atmospheric factors. A further complication is that, in real-world conditions, wind can change every 4–5 seconds. So the shooter begins to wonder what single wind value to enter into the ballistic solver to get an accurate windage solution.
Wind Call uses various mathematical models to transform visual observations of the environment — such as mirage behavior, precipitation movement, terrain influence, and atmospheric conditions — into a usable crosswind value for windage correction. The result can be applied in a ballistic solver or, if a Quick Wind Gun number is configured for the selected ammunition, used directly as a wind hold to achieve a first-round hit.
Created out of frustration
Despite having excellent gear — rifle, optics, ammunition — we kept missing because of the wind. We tried everything. We took every class available to us locally. We searched online. We watched (several times!) the YouTube content of Erik Cortina, Todd Hodnett, Bryan Litz, MDT, Ryan Cleckner, Paul Harrell, Ron Spomer, Jim (Backfire), and many many other popular shooters and guntubers we follow and admire. We learned a great deal from all of them — yet we were still missing because of the wind.
We tested every ballistic calculator we could find — many of them are outstanding, but none could reliably solve the core problem. At best, we could observe (if we were lucky) the first miss and try to correct with a quick follow-up shot before the wind shifted again. Eventually, we realized that reliable first-round hits in windy conditions require more than a ballistic solver — they require a better way to read the wind. So we rolled up our sleeves — and three years later, Wind Call was born. It turned out that, contrary to popular belief, making correct wind calls is not "an art" and not guesswork — not anymore. There is an application for that.
