Wrist Dope
Ballistic calculator for watch
Free · In‑App Purchases
The shot won't wait. New: airgun support — pellet-true ammo, eleven calibers from .177 (4.5mm) to .72, and 5-step dope cards from 10 m.
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, and incline (angle) compensation
- Holds in MIL or MOA — plus velocity, energy, time of flight
- Validated against published reference trajectories
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. On iPhone, landscape puts the control rail on your chosen side.
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.
Ratings & Reviews
Airguns are in. Set up pellets the way the tin prints them: weights to a tenth of a grain (10.4 gr), ballistic coefficients down to 0.005, velocities from 300 fps. Eleven airgun calibers from .177 (4.5mm) to the .72 big bores — pick one and the gun sets itself up: a 30 m zero, a real pellet load, small-quarry targets, and a close-range dial. Springer, PCP, or big-bore slug gun — same engine, honestly applied.
Dope cards now start where you shoot: choose a minimum range and step every 5 from 10 out to 200 — or keep 25s to 1000 for the rifle. The card step lives in Settings and applies to every gun.
Also in 1.15:
- Airgun calibers show their metric bore — .22 Airgun (5.5mm) — for shooters who think in millimeters.
- Energy readouts keep a decimal below 30 ft-lbs, where whole numbers hide what matters.
- Small-quarry ethical-shot floors now rate airgun power honestly instead of calling every pellet insufficient.
The shot won't wait.
