Wind Call Ballistic Calculator

Wind Call is a wind-reading ballistic calculator and field tool designed for precision shooters and long-range hunters aiming for first-shot hits. KEY FEATURES • 7-day free trial Full access to all features so you can evaluate the app in the field. • Multiple self-contained wind-reading methods Use mirage, rain, snow, sun elevation, sky cover, nature signs, and terrain-based cues to calculate effective crosswind and wind hold across a wide range of field conditions. • Advanced Ballistics engine Builds an integrated firing solution inside the wind-reading workflow with drag models, BC/DOPE truing, shot angle, atmospheric inputs, true distance, spin drift, aerodynamic jump, Coriolis, and one-tap shot feedback for drag-model truing. Where supported by the selected wind method, the engine also accounts for headwind and tailwind effects, while Ballistic Breakdown visualizes all applicable corrections. • Ballistic Data, Reticle & Target Libraries Load bullet, ammunition, or pellet data into Advanced Ballistics profiles with manufacturer, caliber/diameter, weight, and category filters. Assign one of 3,000+ scope reticles to each profile and choose a target from the Scope View catalog. • Bluetooth anemometer integration Connect a supported Bluetooth anemometer when available, then use Wind Call’s Gradient workflow to estimate effective downrange wind. • Wind brackets On the Gradient, Mirage, Rain, and Snow pages, capture a low-to-high wind range from a live Bluetooth stream on Gradient, from Mirage/Rain/Snow pattern readings, or manually around an average wind value. With Advanced Ballistics active, the midpoint is used for the main firing solution, while meaningful low-to-high elevation and windage brackets are derived from full ballistic calculations—a feature requested by power users. • Stage Mode A dedicated competition workflow developed at the request of prominent PRS and T-Class competitors. • Practical wind and ballistic solutions Get practical, all-inclusive elevation and windage values in your selected scope units through a true-to-scale Scope View. Moving-target solutions are designed in such a way that you can actually hit them for real—regardless of direction, speed, wind, terrain, or weather. • Offline-first Works fully offline for use in remote areas. • Clean, intuitive, and field-ready UI Designed for high-pressure situations when time is limited. • Built-in User Guide A comprehensive field manual, always available when you need it. Wind Call can be used in two main modes: • Advanced Ballistics mode calculates a complete in-app firing solution using the selected rifle/ammo profile, current atmosphere, target distance, and wind input from multiple wind-reading methods. • Wind Reader Only mode gives you a usable crosswind value from 3 or 9 o’clock for use with your preferred external solver, on a DOPE card, or during rapid target engagements using Quick Wind / Gun Number training. Instead of guesswork, Wind Call provides a structured and repeatable approach to reading the wind across different terrain types and weather conditions. WHO IS IT FOR • Long-range shooters • Hunters • PRS / NRL competitors • ELR shooters • Anyone serious about wind reading, ballistics, and first-shot hits WHY WIND CALL Beyond being a measurement and calculation tool, Wind Call helps you develop fast and reliable wind-reading skills. By combining observation with structured guidance, it improves your ability to interpret conditions and make confident wind calls on your own. The more you use it, the better you become—and the less you need it. Learn more: https://windcall.app/en/
