Ballistic calculator for Wear OS. Dial the range, read your hold, send it.
Read full description
A real ballistic calculator built for the wrist — not a phone app's afterthought. It runs standalone on your Wear OS watch, and the Android phone app is a full app, synced.
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, and time of flight
- Validated against published reference trajectories
LIVE FIRE
Dial the range; the solution updates instantly. A color-coded arrow shows the wind at a glance, and multi-wind previews your holds across wind speeds. The screen stays awake on the gun — no dimming between shots.
RANGE CARD
A full dope table from your chosen minimum, on watch and phone. Tap a row and Live Fire dials to it.
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 on one line. Enter it on the watch or the phone; arm it and the live Stage Card lands on both. Share the sheet as a .wdmatch file and the whole squad imports it.
SCOPE LEVEL — ANTI-CANT
A canted rifle misses wide at distance. Zero the level to your rifle, then hold by ear: pitched cues and an arrival chime, eyes on the target. On the watch and on the phone. A live level sits behind Live Fire, the Range Card and the Stage Card, and your shot angle can come straight from it.
HANDS-FREE VOICE
Long-press Live Fire and ask for dope at a range. The hold comes back spoken and on screen — and it keeps listening, so the next question needs no tap at all. Set your wind and your target by voice too. On the watch and on the phone.
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 retained energy and impact velocity for your game. Never a fake number.
POINT-AND-LOCK THE FIELD
Aim downrange and tap to lock the target; aim downwind and tap to lock the wind, then dial its speed.
YOUR DOPE ON THE WATCH FACE
Six watch-face complications — hold, elevation hold, wind hold, target, density altitude and your active load — plus a Range Card tile that puts eight ranges in two columns. On the phone, a home-screen widget carries the same numbers.
YOUR RIFLES, YOUR LOADS
Build rifle and load profiles right on the watch, with no phone required; a reference-zero badge marks the load your scope is zeroed for. On the phone, 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 as an image or a vector PDF, and back up your whole library to a file you control.
PHONE AND WATCH, ONE LIBRARY
Guns, loads, matches, units and your live shooting state sync both ways. Edit on either device and the other catches up.
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 ads, no tracking, no third-party analytics. Your profiles and readings live on your device. Weather comes from Apple Weather: your location is rounded to a grid before it leaves the phone, and nothing is kept.
Every Pro feature is open during a 7-day trial — no card, no account. Accuracy is never gated.
Built for hunters, PRS and precision rifle shooters, and anyone who wants a first-round-hit hold without unpacking a bag of gear. Requires Android 11 or later; the watch app, Wear OS 3 or later.
Wrist Dope is a calculation aid. Always verify your data and shoot safely, responsibly, and within the law.
