Wind Call
The Hardest Variable

Any solver works well — until wind comes into play

Wind Call is a wind-reading-centered ballistic solver designed for precision shooters and long-range hunters aiming for first-shot hits. Although it is primarily intended for field use, competitors in PRS, ELR, F-Class, T-Class, and NRL Hunter will also appreciate what it can do.

It turns real-world observations — mirage, rain, snow, terrain effects, nature signs, and atmosphere — into a usable crosswind value. Then it uses that value in the Advanced Ballistics engine to produce a complete firing solution while accounting for the full set of other variables that influence point of impact.

A one-week fully functional free trial is provided, giving you enough time to decide whether it is worth the price of a box or two of quality ammo.

The missing input
Solvers need wind. Wind Call reads it.

Most ballistic calculators assume the wind has already been read. Wind Call begins by reading it.

Beyond reading the wind

Things Wind Call does better

Real rifle

Tunes the model to the rifle

Both standard and Doppler-derived custom drag models share the same weak spot: they were measured and validated with a specific rifle, barrel, and ammunition — not with yours. That is where the difference comes from.

Wind Call’s Advanced Ballistics engine lets you tune the drag model with confirmed impacts using one-tap shot feedback, so future solutions are anchored to what your rifle actually does. In practice, the shooter can build a rifle-specific custom drag curve shot by shot.

Max Ord

Reads wind where it matters

The wind at the muzzle is rarely the wind that decides the shot. The strongest influence on point of impact comes from the region around maximum ordinate.

Wind Call shows where that region appears through your scope — in MOA or MRAD above the target — so you read the wind where the bullet feels it most.

Even without visual cues, the app can use wind measured at the firing position, terrain, and gradient models to estimate effective crosswind in the Max Ord region downrange.

Quick Wind

Also known as Gun Number

The Quick Wind concept was created by Todd Hodnett of Accuracy 1st to train elite Tier 1 operators for rapid target engagements. The method is explained in detail in Wind Call’s free in-app User Guide, alongside a wealth of field knowledge drawn from 30+ years of experience by shooters with proven track records (check out the Credits page — no “shooting tips” from paid influencers here).

The number is specific to each barrel/ammo combination, but contrary to popular belief, it is not a fixed constant. Atmosphere and location-specific conditions change it, so Wind Call calculates Quick Wind in real time from the selected gun profile and current atmospherics, keeping you ready for high-pressure situations when time is limited.

Why it exists

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, Ryan Cleckner, 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 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.

Shooters have spoken

And we listened

Initially, Wind Call was released as a wind-reading-only app. The feedback came quickly: users liked the wind-reading workflow, but many did not want to open Wind Call, read the wind, then switch to Strelok, Applied Ballistics, 4DOF, or another solver just to enter that value and get the firing solution. It added time to the kill chain. In short, many users wanted everything in one place.

So here we are. Starting with version 2.3.1, Wind Call includes an integrated Advanced Ballistics engine. It remains focused on reading the wind first, but can now use that wind value directly to produce a complete firing solution in the app. Of course, it can still be used as a dedicated wind reader to complement external solvers.

P.S. We will continue to review all feedback and genuinely appreciate future ideas about what you would like to see improved in the app.
