Precision ballistics,
on your wrist.
WristDope turns your Apple Watch into a long-range ballistics computer. Real-time firing solutions from live sensors and weather — no phone required in the field.
Live Fire
Built for the wrist — not borrowed from a bag.
Kestrel meters and Applied Ballistics solvers are superb tools — and they're also a bag full of gear, a power button, a pairing dance, and an interface built for a handheld. When the shot won't wait, that's friction. WristDope runs the same real physics, straight from your wrist.
The old way
- —Pull out a rangefinder, a Kestrel, and your phone
- —Wait for it to power on and pair
- —Tap through a solver built for a handheld or desktop
- —Read the number, then get back on the gun
With WristDope
- →Raise your wrist
- →Dial range with the Digital Crown
- →Read your hold in MIL or MOA
- →Send it
Same real physics — G1/G7, spin drift, Coriolis. None of the bag.
Live dope & hit probability
Also on your iPhone
A full ballistics app —
no watch required.
WristDope on iPhone is the complete app, not a remote: live firing solutions with hit probability, the full range card, target and wind capture, and your whole gun library on the big screen. Add an Apple Watch and everything syncs automatically — each works fully on its own.
Live Fire
Real-time holdover and windage. Dial the target range with the Digital Crown and read corrections in MIL or MOA — driven by a true Runge-Kutta solver with G1/G7 drag models, spin drift, and Coriolis. Real physics, not a lookup table.
Hit Probability
A live hit percentage on every solution, computed from your rifle's real group size, velocity spread, and wind confidence against your target's size. Know the odds before you press the trigger.
Environment & Wind
Pressure, temperature, altitude, and humidity straight from the watch's sensors and WeatherKit — and point-and-lock wind direction using the compass.
Range Card
A complete, scrollable dope card from muzzle to max range. Tap any row to jump straight to that distance — and it recalculates automatically as conditions change.
Guns & Loads
Build a library of guns and loads, search 150+ factory cartridges, and set a reference zero with per-load offsets that flow straight into the solution. Everything syncs between watch and iPhone.
Complications
Seven configurable watch-face complications put dope on your face: a mini range card centered on your dialed distance, elevation and wind holds with direction arrows, target, density altitude, and active load.
WristDope is a calculation aid for lawful target shooting and hunting. Always follow safe firearms handling practices and applicable laws.
