User Guide
Everything the app does, page by page. The same guide ships inside the app, so it works at the range with no signal.

Guides
- Profiles A profile is one rifle-and-scope setup. Create one profile per rifle, or per rifle-and-load combination, so the solver has accurate inputs. The active profile drives every calculation the app makes.
- Projectiles The projectile attached to your profile supplies the ballistic coefficient, drag model, mass and calibre the solver needs. Pick one from the library, create your own, or supply a custom drag curve.
- Locations & Targets A location is a place you shoot. It holds the range settings and atmosphere; each location contains one or more targets. The active location and target drive the firing solution.
- Loads A load records a handload recipe and its measured performance: components, charge weight, seating depth, and velocity tests. Velocity tests can feed muzzle velocity and its variation with temperature back into your profile.
- Results & Layouts Results is your firing solution, a grid of widgets showing drop, wind drift, DOPE and more for the active profile, location and target. It is fully customisable: what is on screen, how big, and in what order is up to you.
- Sessions & Logging A session is one day's shooting: the shots you fire, against which targets, with what result. Logged shots power the truing and calibration tools that fit the solve to your rifle.
- PRS Stages A PRS stage is more than a list of targets: it is build a position, engage, move, rebuild, engage again, all inside one clock. PRS Stages in the drawer is where you write those stages down and train them.
- Importing Data Getting outside data in: live Bluetooth meters and chronographs, shot files from FX and MagnetoSpeed units, and full loadouts from other ballistic apps such as Strelok. Everything lands as ordinary profiles, loads, sessions and velocity tests you can edit.
- Exporting Data Send a session, a load workup, a shot string or a DOPE card out of the app as a CSV for your spreadsheet, or as JSON for anything that reads it. Exports are a copy of what is on screen, not a backup.
- Backup, Sync & Account Your data lives on your device. Backups and an optional account keep it safe and move it between devices: export and restore a local backup file, or sign in for cloud sync.
- The Web App The browser version runs the same calculator against the same profiles, with two deliberate differences: the ballistics are solved on our servers, and the kit libraries stay there too, so a browser lists the generic entries plus whatever your own saved profiles and loads already use.
- Apple Watch On iOS, a paired Apple Watch can carry parts of your firing solution to your wrist. The drawer shows a Watch Connected badge when a watch is paired and reachable.
- Garmin A Garmin watch can carry your target cards and DOPE table on your wrist, the same way an Apple Watch or Wear OS watch does. It needs the Garmin Connect app on your phone and the Dopeology app from the Connect IQ Store.
- Settings & Units App-wide preferences live under My Profile, Data & Sync in the drawer; units are set per profile. Every change applies immediately.
Widget Reference
- Drop The elevation correction needed to hit the active target at its range, shown in your chosen dial units alongside the raw drop.
- Wind Drift The windage correction at the active range, either a low/high band across a range of wind speeds, or one figure when you work from a single wind value.
- Target Card A summary of the targets at the active location and their key solve values (range, elevation and windage), so a whole location reads at a glance.
- Scope View A reticle drawing with the point of impact placed at the active range, a through-the-scope preview of the hold, with working turrets.
- Wind Input Sets the wind speed and direction used by every wind-dependent solve, via a dial and speed control that the rest of the grid follows.
- Wind Meter Drives the wind from a connected wind meter (Calypso ultrasonic or WeatherFlow WEATHERmeter). It writes into the same wind state as Wind Input, so the dial and every wind-dependent solve follow along.
- Wind Chart A live plot of wind speed over time from a connected wind meter, with direction and the session's minimum and maximum.
- Quick Settings A single card of transient solve-time overrides for "what if" tweaks (range, muzzle velocity, atmosphere) without editing the underlying profile.
- KZ Rangefinder Estimate range by bracketing the kill zone, or any known-size target, in your reticle, inverse mil- or MOA-ranging done in the head, on the line.
- Target Selector A slim dropdown of the current location's targets. Picking one makes it the active target, the one every other widget solves and displays for.
- Shot Log On-page shot entry for the active shooting session, the same table the Log Shot modal uses, kept on the grid so logging never leaves Results.
- DOPE Card A full trajectory table at the current wind settings, the card you would tape to a stock. Columns and range step are configurable per instance.
- Trajectory Chart A configurable XY line chart of the solved trajectory. One widget covers most of the obvious plots (drop over distance, drop over time, velocity or energy over range) via axis selectors.
- Danger Space The point-blank range and danger space for a given vital-zone size, the range band over which you can hold dead-on and still hit the vital zone.
- Impact View A face-on view of the target at the active range, with the predicted point of impact plotted on it, so you can see where the shot lands relative to your aim and how far off it is.
- Positions A plan view of the firing point and the targets around it, range and bearing at a glance, and a tap away from each target's dope.
- Group Analysis A shot-group scatter plot with group statistics (extreme spread, mean radius and the centre of the group) drawn from your logged shots.
- Drag Curve The drag coefficient (Cd) against Mach number for the active drag model: the reference curve the ballistic solve is built on.
- Truing Table Predicted versus measured drop from your logged shots, so you can see how well the solve matches reality and where to true your data.
- Sensitivity How much your point of impact shifts at the active range when key inputs are off, a quick read on what actually matters at distance.
- Projectile Compare (Chart) Overlays two projectiles' trajectories from the same rifle setup (same zero, atmosphere and wind), so the difference is down to the bullets alone.
- Projectile Compare (Table) A side-by-side dope table for two projectiles from the same rifle setup, with the difference per row, the numbers behind the compare chart.
- Shot Timer A practice drill timer with a random start beep, par time, and shot splits, optionally driven by the microphone so real shots stop the clock.
- PRS Stage Trainer Runs one of your saved PRS Stages against the clock, build the position, engage the targets, move, rebuild, engage again.
- F-Class Plotter A scoring target you tap to mark shots, with running totals fed to the shot log and a choice of scoring systems.
- Velocity Chart Velocity per shot for the active session, as a chart or a table, with chronograph readings flagged among any manual entries.
Tools Reference
- BC Calibrator Fits your projectile's ballistic coefficient to reality, using the shots you have logged with measured drop. Where the Truing Table shows you the error, the calibrator removes it.
- Group Analyser A photo-based shot-group measurer. Photograph your target, mark the shots, and get the group's size and statistics. No ruler at the bench.
- Bench Rest Scorer A photo-based scorer for multi-bull bench rest cards. Photograph a shot card, align the grid, and the tool gauges every impact and totals the score.
- Convertor A quick unit convertor for the measurements shooters juggle, so there is no leaving the app to check a conversion.
- Muzzle Energy Calculator Energy from a velocity and a projectile weight, on its own screen. Type the two figures in whatever units you have them in, read the answer in joules or ft-lbf, and check a load against a class limit or a quarry requirement without touching a profile.
- Stability Calculator Miller gyroscopic stability (Sg) for any bullet, twist and velocity, corrected for temperature and altitude or station pressure. Prefilled from your active profile and location, with every input editable so you can try a different bullet, barrel or day.
