All readings below come from one demo data set: .308 Win, SMK 175 gr, 100 yd zero, solved at 600 yd.
One card covers one rifle, one load and one zero. Change any of the three and a new card is created, so the conditions a card applies to are never in doubt.
What matters in a saved load is its ballistic coefficient. The BC used by the solver is shown in large type with its source: manufacturer, fitted from the box table, or custom. Edits step by 0.001, and the panel shows the difference from the manufacturer value and its effect on the 600 yd elevation.
Zeroing runs in four steps: set up, check, plot and adjust. It does not start while optic parameters are missing or the target size is unconfirmed; once the impacts are plotted on the target, it gives the turret direction and click count from the shots fired and the optic’s click value.
Draws where to hold on the reticle from the current solution. Drop reads in angle only — no target face holds the three metres it falls at six hundred. In wind the whole trajectory leans to one side on the glass, and that lean says more than a column of numbers.
Rifles, optics and ammunition are recorded separately and combined into a setup. When creating one, you search the factory rifle catalogue by brand and model, and the configuration, barrel length and twist come with it; sight height is measured with the help of a diagram.
Without a laser rangefinder, distance is estimated from an object of known size in the frame: the viewfinder boxes the objects it recognises, and tapping one locks it and gives both its distance and its crossing speed, ready for the solver and the reticle; you can also bracket the target’s top and bottom by hand. The tools page also has a conditions card, a compass and a level, and the weather readings feed straight into the solver.
Sorting data indoors, a sunlit range and a night firing point each ask something different of the screen. The display mode is chosen by the shooter.
Light ground, dark type, the densest of the three. Suited to sorting data indoors and looking up ammunition and factory rifle specifications.
Equipment parameters, ammunition data, DOPE data and photos belong to the user, who decides item by item whether anything leaves the device.
Solving, zeroing and ranging all run on the device, and the app is fully usable without signing in.
Signing in is not consent to upload. Syncing the equipment library and DOPE requires your consent, which you can withdraw at any time. Photos are never synced.
The backup exports as a single zip containing local records and photos and can be restored on another device; the account and all local data can be deleted from within the app at any time. The privacy policy and terms ship with the app and are readable offline.
Distance in m or yd, length in mm or in, angle in MRAD or true MOA, and readings can be given in scope clicks. Units are chosen per form; no global setting has to be changed.
No. Solving, zeroing and ranging all run on the device. A connection is used only for cross-device sync, catalogue search and weather lookups, and sync requires your consent first.
It gives an estimate with its error percentage: the more certain the reference size and the more pixels the target covers, the smaller the error. A telephoto lens is recommended; where available, a laser rangefinder takes precedence.
No. Zeroing targets, ammunition box tables and rangefinder frames all stay on the device. To move them, export a backup and keep it yourself.
Yes. The backup is a single zip file containing the locally stored records and photos, and it can be restored on another device.
