Wrist Dope vs FieldSolve

A real ballistic calculator built for Apple Watch first — not a phone app's afterthought. It runs standalone on your wrist; the iPhone companion is a full app, synced. FREE TO DOWNLOAD The full calculator is free on iPhone and Apple Watch. Wrist Dope Pro — a one-time $39.99, no subscription — unlocks wind meters, Field Trueing, Match Mode, scanning, Siri, auto environmentals, live complications, printable range cards, and unlimited profiles — buy or restore on the watch. Accuracy is never gated. WHEN THE SHOT WON'T WAIT No time to thumb through a calculator. Raise your wrist, dial the range, read your hold. Send it. Glanceable and dial-driven, with real math underneath. A SERIOUS ENGINE, NOT A TOY - True point-mass solver with G1/G7 drag models - Coriolis, spin drift, aero jump, and incline compensation - Holds in MIL or MOA — plus velocity, energy, time of flight - Validated against published reference trajectories - Advanced Settings (Pro): switch each correction on or off LIVE FIRE Dial the range; the solution updates instantly. A color-coded arrow shows wind at a glance; multi-wind previews holds across wind speeds. The display stays awake on the gun. On the rifle, target angle and cant update your holds live. WIND METERS Connect a Kestrel or a WeatherFlow Tempest or WEATHERmeter from the iPhone or straight from the watch. Its wind, temperature, pressure and humidity flow into your holds. FIELD TRUEING Correct the solver to what your rifle actually did: true muzzle velocity from a chronograph or a group at distance, then BC on a transonic target. It checks your zero first and refuses ranges that can't tell you anything. MATCH MODE — STAGE CARD AND STAGE TIMER Build a match as stages and targets, then glance-read the active stage: every target's range and live-solved holds. Arm the par timer on the watch or iPhone and both count down together — the screen edge drains, and haptics, range beeps, or a spoken countdown call the time. Hunter stages: log each target as you find it, then engage in order. On iPhone, RO mode puts one big button in the RO's hand. Share a match as a file — the whole squad imports it. AIRGUN READY Eleven airgun calibers, .177 to .72, with pellet-real weights and BCs. SCOPE LEVEL — FREE ANTI-CANT A canted rifle misses wide at distance. Zero the level to your rifle and hold by ear — audio and haptic cues, eyes on target; a glow, ring, bars or footer shows level. Pro puts a live level behind Live Fire, the Range Card, and the Stage Card. HIT PROBABILITY AND THE ETHICAL SHOT Lock a target for a real first-round-hit percentage from your velocity SD, group size, and wind call, plus a terminal check for your game. HANDS-FREE WITH SIRI "Hey Siri, Dope for 250" speaks your hold — watch and iPhone. Wind and target by voice, too. POINT-AND-LOCK THE FIELD Aim downrange, tap to lock target; aim downwind, tap to lock wind — read on the shooter's clock face. RANGE CARD ON YOUR WRIST A full dope table — dial to scroll — plus seven watch-face complications: a mini range card, holds, target, density altitude, and active load. YOUR RIFLES, YOUR LOADS Build rifle and load profiles on the watch — no phone required. On iPhone, scan a factory ammo barcode and the load builds itself, or pick from a bullet catalog with factory BCs. Export a printable dope card; back up your library to a file you control. YOUR CONDITIONS, YOUR UNITS Pressure, temperature, altitude, humidity, and wind each toggle AUTO or MANUAL. Metric or imperial, synced across devices. PRIVATE BY DESIGN No accounts, no tracking, no third-party SDKs. Your profiles and readings stay on your device. Weather comes from Apple Weather on request. Built for hunters, PRS shooters, and airgunners who want a first-round-hit hold without unpacking a bag of gear. Runs on Apple Watch Series 4 and later. Wrist Dope is a calculation aid. Always verify your data and shoot safely, responsibly, and within the law.

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.
