MOAScorer
Read full descriptionHide full description
MOA Scorer turns a photo of your printed sighting target into precise group measurements — no ruler, no math. Shoot your group on a supported grid target, snap a photo with your phone, enter your distance, and MOA Scorer reads each diamond and reports: • Extreme-spread group size in both MOA and inches (center-to-center) • Point-of-impact offset from your aim — windage and elevation — to help dial your zero • A clear annotated image of every group Because the target grid is a fixed physical scale, your group size in inches is exact regardless of range, and true MOA is computed from the distance you enter. SUPPORTED TARGETS • Action Target SI-13MPD "Rifle Sighting Target" • Thompson Target HALO 4643 "Scope Alignment" BUILT FOR PRECISION RIFLE Tuned for centerfire and rimfire precision shooting (roughly .17–.30 caliber), including tight, overlapping groups. YOU'RE IN CONTROL Auto-detection does the work, but you can fix anything: tap into any diamond to add or remove a shot, or drag the aim point to the true center — group size and sight adjustments recompute instantly. MOA Scorer runs entirely on your device. Point, shoot, photograph, measure.

FieldSolve is a fast, accurate ballistic calculator built for long range shooters, hunters, and precision rifle competitors who need a firing solution they can trust on the first shot. Enter your rifle, load, and conditions and FieldSolve solves the full trajectory — bullet drop, windage, and the exact hold or dial in MOA or mils. BALLISTIC SOLVER A precision ballistic engine that accounts for muzzle velocity, ballistic coefficient (G1/G7), zero range, sight height, shooting angle, spin drift, aerodynamic jump, and Coriolis. Get your holdover and windage instantly, as a dialed solution or a reticle hold. BUILT FOR THE FIELD Save unlimited rifle and load profiles. Build range cards and DOPE charts for every distance. A clean heads-up display gives you the numbers you need at a glance, even on the clock. LIVE ENVIRONMENTAL DATA Wind, temperature, pressure, humidity, and density altitude all change your solution. Enter them by hand, or connect a weather meter to pull live atmospherics straight into your solve. Connect an anti-cant level to read your rifle's true cant, and import muzzle velocity directly from your chronograph so your data is real, not estimated. RECORD YOURSELF SHOOTING FieldSolve records video of your shot with a live data overlay — your solution, wind, cant, and velocity burned right onto the clip. Review your form, confirm your DOPE, and share your best shots. FEATURES - Advanced ballistic solver with G1 and G7 drag models - Bullet drop, windage, and lead in MOA, mils, or clicks - Spin drift, aerodynamic jump, and Coriolis - Unlimited rifle and load profiles - Range cards and DOPE charts - Angle (cosine) and cant correction - Metric and imperial units - Live weather, level, and chronograph integration - Video recording with data overlay FieldSolve is a free ballistic calculator. Whether you shoot PRS, NRL, F-class, or hunt at distance, it gives you a firing solution you can rely on. Always follow safe shooting practices and know your target and what lies beyond it. Ballistic solutions are calculated estimates; confirm your come-ups on paper before relying on them in the field.
