Wrist Dope

The shot won't wait. New: Advanced Settings (Pro) — switch spin drift, aero jump, and Coriolis individually and see what each one adds to your hold.

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 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 dig out a wind meter and thumb through a calculator. Raise your wrist, dial the range, read your hold. Send it. Most tools make you pick fast or accurate; Wrist Dope refuses — 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 — no dimming between shots.

MATCH MODE — THE STAGE CARD, SOLVED Build a match as stages and targets, then glance-read the active stage: every target's range and live-solved holds, with the shot order in one line. Enter on watch or iPhone; arm it and the live Stage Card lands on both. Share the sheet as a .wdmatch file — the whole squad imports it.

AIRGUN READY Pellet-real ammo — tenth-grain weights, BCs to 0.005 — and eleven airgun calibers from .177 (4.5mm) to the .72 big bores. Pick one and the gun sets itself up — 30 m zero, real pellet load, small-quarry targets, close-range card.

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. Free on watch and iPhone. Pro puts a live level behind Live Fire, the Range Card, and the Stage Card — and takes shot angle from it.

ON THE RIFLE Mount the watch at any angle and set the screen to match — bearings and level sensors adjust.

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 rating energy and impact velocity for your game. Never a fake number.

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 and dial speed — read on the shooter's clock face.

RANGE CARD ON YOUR WRIST A full dope table from your chosen minimum. Dial to scroll; rows auto-center.

YOUR DOPE ON THE WATCH FACE Seven complications: a mini range card on your dialed distance, holds, target, density altitude, and active load.

YOUR RIFLES, YOUR LOADS Build rifle and load profiles right on the watch — no phone required; a reference-zero badge marks the load your scope is zeroed for. On iPhone, scan a factory ammo barcode and the load builds itself — caliber, bullet, BC, muzzle velocity — or pick from a bullet catalog with factory BCs. Export a printable dope card, and back up your library to a file you control.

YOUR CONDITIONS, YOUR UNITS Pressure, temperature, altitude, humidity, and wind each toggle AUTO (sensors) or MANUAL. Metric or imperial — one switch or per-unit overrides, 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, precision shooters, airgunners, and anyone who wants 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.
