Ballistics is a ballistic calculator. It's a perfect companion for hunters and long range shooters who occasionally need to accurately hit a target at a different range to what the rifle has been zeroed to.

Disclaimer: the application uses generic ballistics formulae which should be accurate enough for hunting use. For shots longer than 250m (or 270yds) the calculations should be verified at shooting range to make sure the calculated values match your specific cartridge and gun combination. The calculations are heavy and take more time the farther the target is. The app initializes on first calculation and when the settings are changed, which takes between 1-2 minutes.

Features:
- Calculates bullet drop and sight click adjustment based on target range, target angle and current wind conditions 
- Results are adjusted by temperature, altitude and pressure values read from the sensors (can be turned off in the app settings)
- App supports both statute and metric units
- Sight and cartridge configuration is done via Garmin Connect settings (in statute units only). App's "settings" menu is only for viewing current settings.
- All input dialogs are native
- Current configuration can be viewed in the app in a scrollable list
- Latest version added support for Fenix 3, D2 Bravo and Vivoactive, unfortunately it's not tested with real devices. Let me know in comments if they work


Note that versions 1.3 - 1.38 were faulty because of a bug in Android version of Garmin Connect. Please give positive feedback if this works on your device :)
