Brass Log vs MilliDope

A comprehensive and modular logging app that provides all you need to log your firearms usage and see metrics on both firearm and components over time.

MilliDope tells you how many clicks to dial for each target at your range. Step through your targets, dial each adjustment, and shoot. Your rifle, your ammunition, and your targets are configured independently. Change your load without touching your rifle. Shoot a new range without re-entering your ballistics. MilliDope keeps the complexity organised so you don't have to carry it. When a shot doesn't land where expected, tap where it hit in the spotter view. MilliDope calculates your correction and uses the deviation to refine its wind estimate — so each shot informs the next. Atmosphere matters at distance. MilliDope fetches live weather conditions automatically using your GPS location, pulling from professional meteorological services that measure conditions across your entire shooting environment — not just at your feet. It updates in the background while you're in position. Large inputs and buttons work with gloves on. All trajectory calculations run locally on your device. Share any rifle, ammunition, or range configuration as a QR code. Five drag models: G1, G5, G6, G7, and GS. Coriolis effect from your GPS latitude. Gyroscopic spin drift from your rifling twist and direction. Cant, shot angle, and barrel azimuth. Kinetic energy, Mach number, and time-of-flight at every range point. Subsonic warning included. Calibrate a real ballistic coefficient from observed behaviour No built-in bullet database — because your load data comes from your manufacturer or your own measurements, not marketing copy. Enter it once and it's yours. Always available, always up to date.
