The app contains several screens.
Languages can be selected between English, German and Russian on the “Letter of agreement” screen. The information on this screen requires your approval.
Each time you restart, the "Letter of agreement" screen is skipped. From the "Settings" screen you can switch back to the "Letter of agreement" screen.
In the "Settings" screen, the settings for the ammunition and zeroing data can be made. The units of measurement are also selected in the "Settings". The selection of the units of measurement is not subject to a unit system and can be combined as desired. For example, the distance in yards and the bullet diameter in millimeters can be selected.
The "calculator" is the main screen. Each time you restart, this screen appears. The ballistic calculations can be done here.
The current weather conditions, the shooting distance, the shooting angle and the cross wind with wind direction are required for this. The information can be entered traditionally using the keyboard or using operating levers (buttons, sliders, swiches).
The "Table symbol" and "Reticle symbol" buttons are black and deactivated if the calculation needs to be updated.
The "distance table" screen gives physical values for the respective flight distances of the bullet. The table consists of four columns. Each column can output a certain physical value at will. You can choose from eleven values. This allows four columns to be combined as desired. For example, the projectile energy can be displayed in the first column and the fall height in the last column or vice versa. The settings are saved and loaded with every restart. With the setting "Step" the flight distance increment can be changed. The smallest increment is one meter/yard. Please keep in mind that very small increments with very long flight distances require a lot of computing power and can cause your device to crash. The final flight distance is the distance from the "calculator".
In the "Reticle" screen flight distance data and wind data for different reticles can be calculated. There is a choice of seven rifle scope suppliers with reticles for a total of over 150 rifle scope models. The scan / zoom switch can be used to switch between the functions for separately enlarging the reticle and for scanning the reticle. The reticle includes two target pointers. The red target pointer calculates the reticle values according to the „calculator“ input. The yellow target pointer calculates any point on the reticle within the flight parabola of the bullet. To do this, the Scan / Zoom switch must be set to scan. The yellow target pointer is behind the red target pointer. In the scan position, the yellow target pointer can be moved over the reticle with your finger. The red target pointer can disappear from the field of view of the reticle. The yellow target pointer always remains in the field of view of the reticle.
With the "arrow symbol" button the calculation is updated within each screen. This button turns red when an update is required.
Each screen has a "question mark symbol". This will activate the explanation screens.
Other special features are the magnifying glass symbols on the screens: "Settings", "Calculator" and "Reticle". The display screen can be reduced or enlarged with the magnifying glasses. The states of the displays are saved and loaded when restarting.
