Ballistic Solver
Generate firing solutions from rifle, ammunition, range, angle and environmental inputs, then open Analyze Ballistics for a full downrange Velocity / Flight Profile through the transonic transition.

COMPLETE WORKFLOW
Everything a precision shooter needs in one application
Build profiles, capture conditions, calculate solutions, manage targets and retain shooting records without stitching together multiple tools.
Weather Integration
Use phone weather or compatible Bluetooth weather meters with controlled snapshots.
Load Development
Plan OCW and Ladder testing, capture chronograph data, notes and impact locations.
Target & Range Cards
Prepare reusable, field-ready firing solutions for targets and distance bands.
Sessions & History
Record equipment, conditions, notes and outcomes in a structured history.
Backup & Restore
Export user-controlled backups for safekeeping and supported-device transfer.
Wind Effect
Understand directional wind effects and compare practical wind scenarios.
Direction of Fire
Use GPS, compass and true-north workflows to support consistent calculations.
Universal Loader
Control a compatible BLE powder dispenser — AutoTrickler or RCBS ChargeMaster Link — directly from Tools.
Rimfire Support
Dedicated rimfire caliber picker, a factory-ammo quick-pick catalog, and solver defaults tuned for .22 LR, .22 WMR, .17 HMR and more.
PCP / Air Rifle Support
Entirely free — a third rifle platform alongside centerfire and rimfire — bore-size picker, pellet/slug working loads, a 306-entry projectile catalog, and conservative physics that never borrows the centerfire stability model.
Match / Stage Mode
Build a Match from Stages and Targets, recalculate the whole match against live weather, then run it one-handed with large-number, swipe-through live navigation.
Hit Probability
How likely your first shot is to hit your target — 10,000 simulated first-round shots with your wind, range and group errors, what's costing you hits, and every saved rifle ranked by hit % for the same shot.
ELR Trajectory Diagnostic
Enter real observed DOPE at 2–6 distances and find out why long-range impacts diverge from the predicted trajectory — a read-only calculator that fits Zero Offset, Muzzle Velocity, Global BC/Drag and Velocity-Banded BC, ranked by RMSE across every shot.
Equipment Reach Planner
Check whether a rifle's scope and rail/base can mechanically dial a target distance, and if not, get a ranked GET ME THERE plan — rail size, mount, minimum scope travel to shop for, or an external elevation device — instead of just a shortfall.
Velocity Loss BC Calculator
Work out a real drag parameter from your own chronograph readings instead of trusting a published number — rifle-driven with an automatic G1/G7/RA4 drag model; one reading gives a single effective result, several give independently solved segments per velocity window.
Import from Other Apps
Switching from Strelok or Applied Ballistics/Kestrel? AB/Kestrel data imports as new rifles; Strelok's loads attach onto your existing rifles instead, since its own rifle-level fields have proven unreliable.
