Wrist Dope

A real ballistic calculator built for Apple Watch first — not a phone app's afterthought. The firing solution lives on your wrist and runs standalone; the iPhone companion is a full standalone tool, synced to the watch. FREE TO DOWNLOAD The full calculator is free on iPhone and Apple Watch. Wrist Dope Pro — a one-time $39.99, no subscription — unlocks scanning, Siri, automatic environmentals, live complications, printable range cards, and unlimited profiles. Buy or restore Pro right on the watch. Accuracy is never gated. WHEN THE SHOT WON'T WAIT No time to dig out a wind meter and thumb through a calculator. Raise your wrist, dial the range, read your hold. Send it. FAST. ACCURATE. SIMPLE. Most ballistics tools make you pick two. Wrist Dope refuses. Glanceable and dial-driven — no keyboard, no buried menus — with real math underneath, not a watered-down estimate. A SERIOUS ENGINE, NOT A TOY - True point-mass trajectory solver with G1/G7 drag models - Coriolis effect, spin drift, and incline (angle) compensation - Elevation and windage holds in MIL or MOA — plus velocity, energy, time of flight - Validated against published reference trajectories LIVE FIRE Dial the range; your solution updates instantly. A color-coded wind arrow shows direction at a glance; multi-wind mode previews holds across wind speeds. The display stays awake on the gun — no dimming between shots. SCOPE LEVEL — FREE ANTI-CANT A canted rifle misses wide at distance. Zero the built-in level to your rifle and hold by ear — audio and haptic cues, eyes on the target. Free on watch and iPhone. Pro puts the level beside your Live Fire holds and takes shot angle straight from it. ON THE RIFLE Mount the watch at any angle and set the screen to match. Target bearings and level sensors adjust accordingly. On iPhone, landscape puts the control rail on your chosen side. Screen rotation is a Pro feature. HIT PROBABILITY AND THE ETHICAL SHOT Lock a target and see a real first-round-hit percentage from your load's velocity SD, group size, and wind-call confidence — plus a terminal check rating retained energy and impact velocity for your game. Never a fake number. HANDS-FREE WITH SIRI "Hey Siri, Dope for 250" speaks your hold without raising your wrist — on watch and iPhone. Set wind and target by voice, too. POINT-AND-LOCK THE FIELD Aim your wrist downrange, tap to lock target direction and angle. Aim downwind, tap to lock wind, dial the speed. Wind reads on the shooter's clock face with the crosswind that moves your bullet. RANGE CARD ON YOUR WRIST A full dope table across your range. Dial to scroll; each row auto-centers — range, elevation, windage, velocity. YOUR DOPE ON THE WATCH FACE Seven configurable complications: a mini range card centered on your dialed distance, elevation and wind holds, target, density altitude, and active load — each taps into its screen. YOUR RIFLES, YOUR LOADS Build and edit rifle and load profiles right on the watch — no phone required. A reference-zero badge marks the load your scope is actually zeroed for. SCAN A BOX, BUILD A LOAD Scan a factory ammo barcode on iPhone and the load builds itself — caliber, bullet, BC, and muzzle velocity. Pick from a bullet catalog with factory BCs. TAKE YOUR DOPE ANYWHERE Export a printable dope card to PDF or AirPrint, or back up your gun library to a file you control. YOUR CONDITIONS, YOUR UNITS Pressure, temperature, altitude, humidity, and wind each toggle between AUTO (sensors) and MANUAL. Metric or imperial — one switch or per-unit overrides, synced between iPhone and watch. PRIVATE BY DESIGN No accounts, no tracking, no third-party SDKs. Your profiles and readings stay on your device. Weather comes from Apple Weather only when you ask for it. Built for hunters, PRS and precision shooters, and anyone who wants a first-round-hit hold without unpacking a bag of gear. Wrist Dope is a calculation aid. Always verify your data and shoot safely, responsibly, and within the law.
