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
Real-time holdover and windage solutions. Dial the target range with the Digital Crown and read corrections in MIL or MOA to match your scope.
Environment & Wind
Live conditions from the watch's sensors, temperature and wind via 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 to that distance — and it auto-updates as conditions change.
Gun & Load Profiles
Build a library of guns and loads, search 150+ factory cartridges, set a reference zero with per-load offsets, and track group size and velocity SD.
Full Physics Engine
G1/G7 drag models, spin drift, and Coriolis — a real Runge-Kutta trajectory solver, not a lookup table.
Built for the Wrist
Digital Crown-first, glanceable, glove-friendly. Works standalone on Apple Watch Ultra and Series watches — no phone required in the field.
WristDope is a calculation aid for lawful target shooting and hunting. Always follow safe firearms handling practices and applicable laws.
