GVX Ballistic Solver
For precision shooting
$22.99 · In‑App Purchases
GVX is the ballistic solver for sport, precision and long-range shooting, independently conceived and developed by Giuseppe Valtorta, founder of Victrix Armaments.
It is not built on theory alone: it is validated with real measurements, Doppler radar data and complex measuring systems, using the same method with which Victrix rifles are designed and tested.
TRAJECTORY AND FIRING SOLUTION
• Full trajectory with drop, wind drift, spin drift, aerodynamic jump, Coriolis and Eötvös effect
• Corrections in Mil or MOA, as turret clicks and as holdover on the reticle, with the reticle library
• Target output, range card, drop tables, moving target and milling
• MRD (most recommended zero), Speed Drop Factor and maximum range
• Dashboard: elevation, windage and shot data on a single screen, with a night theme too
ATMOSPHERE AND WIND
• Temperature, pressure, humidity and altitude, with muzzle velocity following powder temperature
• Single wind, wind zones or wind reading points along the trajectory
• One-tap weather from the internet when a connection is available
AMMUNITION AND BULLETS
• Catalogue of over 4,000 factory loads and bullet library with G1 and G7 coefficients
• Gyroscopic stability (Sg) of the bullet in your barrel
YOUR DATA
• Rifles, loads, positions and settings saved by name
• Import of profiles from other apps and of bullet libraries, export of results
• Print and PDF of every page
• Italian and English; metric or imperial units chosen quantity by quantity
• All calculations stay on the device and work offline
GVX PRO — ONE-TIME IN-APP UPGRADE
• Predictive hit-probability analysis
• Loophole, the precision-match exercise
• Real ballistic coefficient from radar data and measured drag curve
• Ballistic coefficient from your own shots
• Cant analysis
• Import from Garmin Xero and Labradar chronographs
• Angle of site measurement with the phone
• Share data with a fellow shooter: the .gvx file opens directly in GVX
• Apple Watch: elevation, windage and cant on your wrist, updated automatically

GVX is a calculation tool for sport, precision and long-range shooting. Results must always be verified on the range: the shooter remains responsible for the use of the firearm, in compliance with the laws of their country.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
First GVX update:
- On phones the GVX name and title are centred on the screen.
- Console, Target view: after every change the target list stays on the selected target instead of jumping back to the top.
- Full-screen Console: with the Console open the whole screen stays dark, with no light bands.
- Console, Target view: the wind changed in the Console also updates the range card list.
- In night mode the enlarged reticle keeps the chosen colour; no values are cut off in the Console.
