Trajex is a serious exterior ballistics calculator for precision rifle shooters and handloaders. Built around two real solvers — a Modified Point-Mass engine for fast field solutions and a full 6-Degree-of-Freedom rigid-body solver for extreme-range and transonic work — it gives you the math the load actually deserves. No subscriptions. No accounts. No ads. No telemetry asking you to log in to see your own data. TWO TRAJECTORY ENGINES • Modified Point-Mass (MPM) — fast, accurate solutions for normal shooting envelopes using G1 or G7 ballistic coefficients. • 6-DoF rigid-body solver — full angular dynamics for long-range, high-angle, and transonic regimes where point-mass models break down. Choose the engine per shot. Compare the difference on the same chart. BULLET & LOAD MANAGEMENT • 1,279-bullet database spanning 15 major manufacturers, with G1 and G7 BCs where published. • Build rifles with photos, twist rate, sight height, zero range, and scope configuration. • Manage loads as rifle-independent recipes linked by cartridge — one load works across every rifle chambered for it. • 405-cartridge CIP catalog with 401 official TDCC specification PDFs for dimensional reference and load workup. ATMOSPHERE THE WAY IT ACTUALLY IS • One-tap GPS location capture. • Live atmospheric data from Open-Meteo: pressure, temperature, humidity, wind speed and direction. • Or enter conditions manually when you're underground, off-grid, or just don't trust the forecast. Coriolis effect and gyroscopic spin drift are computed automatically from your latitude, azimuth, and bullet spin — not toggled on as a gimmick. RESULTS YOU CAN ACT ON • Drop, windage (left/right), remaining velocity, energy, and time of flight at every range step. • Interactive trajectory chart with separate ELEVATION and WINDAGE views — drag along the curve to read any range. • SCOPE tab renders your reticle with true MOA or MIL graduation, showing the holdover and wind hold for the target distance. • Imperial and metric units, switchable globally. BUILT FOR THE BENCH AND THE FIELD • Dark "precision-instrument" interface designed to be readable at the bench, in the truck, and on the line. • Local-first storage. Your rifles, loads, and zero data live on your device. • Backup and restore that MERGES — restoring a backup never deletes what's already there. Move between devices without fear. WHO THIS IS FOR Trajex is built for handloaders, F-Class and PRS competitors, hunters working past 600 yards, and anyone who reads "BC at Mach 1.2" and wants to know which model the number came from. If you've ever squinted at a free ballistics app and wished it had the math, the data, and the discipline of a real tool — this is that tool. WHAT TRAJEX IS NOT It is not a rangefinder. It is not a wind meter. It does not pretend your phone's barometer is a Kestrel. It will not upsell you a "pro" tier to unlock features you already paid for — because you didn't pay anything. Free. Built by a shooter, for shooters. Feedback welcome

Verdict
The clearest difference is device support: trajex at 3 against Public Mobile's 1. trajex also leads on iOS requirement (13.0 vs 16.1). On price, update cadence, ads and in-app purchases there is nothing between them.
