Zeroed: Ballistics Calculator

Zeroed is an offline ballistic calculator for hunting and long range shooting. Get bullet drop, wind and a printable DOPE card in seconds. Pro adds a Lab for your range data: chronograph import, group size from a photo, load development, hunt planner and archery. No account, no ads, no subscription. Pick a factory load, enter your scope and zero, and read your elevation and windage hold in MRAD, MOA or clicks. Big numbers, readable in full sun and with gloves. WHY ZEROED • 100% offline, even in airplane mode. No account, no ads, no tracking. • Math you can check: the ballistics solver agrees with an independent open-source solver within 0.33% (worst case) across 7 cartridges and 42 ranges. THE BALLISTIC CALCULATOR • Point-mass RK4 solver, G1/G7 BC and multi-BC • Temperature, pressure, humidity, altitude or your phone's barometer • Wind bracket, segmented wind, shooting angle • Spin drift, Coriolis and truing (Pro) • DOPE chart to 2000 m / 2200 yd (Pro), shared as an image or a PDF card • Sun and Night (Pro) themes, glove-size 48 dp controls LAB (PRO) • Chronograph: import a Garmin Xero or LabRadar CSV, or type velocities in. Average, ES and SD with 90% confidence ranges and an honest "enough shots?" hint. Set your MV from a string, or work out temperature sensitivity. • Group size from a photo: set the scale, tap your aim point and the holes. ES, mean radius and CEP in MOA and MIL, the point-of-impact offset, and one tap to apply it as a zero offset. • Load development log: ladder, OCW and seating tests on a velocity chart that finds flat spots (nodes) and flags any that "may be chance". • Brass tracking: firings, annealing and trimming per lot. • Hunt planner: sunrise, sunset, civil twilight and moon times, MPBR, and energy floors for Germany (§19 BJagdG), England and Wales (Deer Act), Scotland, Sweden and Colorado, plus guidelines. Always check local regulations. • PRS stage card: a printable DOPE strip and wrist-coach panels. • Archery: arrow trajectory, KE, momentum, FOC and a bow sight tape fitted from your marks, printed 1:1. 5,000+ BULLETS AND FACTORY LOADS 2,300+ factory loads and 2,900 bullets across 150+ cartridges, .17 HMR to .50 BMG, rimfire and airgun pellets included.

No account, no subscription. Does it read my chronograph? It imports CSV exports from Garmin Xero and LabRadar, or any CSV with a velocity column. File import, no Bluetooth. Does it need the camera? No. Groups use the system photo picker, so no camera or storage permission. Does it give load data? No, never. The log records your own tests. Do sun times need location permission? No. You type coordinates once. Which cartridges? 150+, like 6.5 Creedmoor, .308 Win, .223 Rem, .30-06 and 6.5x55, or any custom load.
