Strelok Pro v4.1.7 [Paid]

This is a smart ballistic calculator. It can use G1, G7 and... custom drag-functions!

Can calculate trajectory without using ballistic coefficient!
Can calculate spin drift, Coriolis effect, gyroscopic stability factor, Coriolis effect and vertical deflection of crosswind.
3182 cartridges database
1184 bullets database + 411 bullets with G7 ballistic coefficients
Powder temperature considering.
Supports imperial and metric units.
Supports density altitude.
Can calculate spin drift, gyroscopic stability factor and vertical deflection of crosswind.
Can calculate Coriolis effect.
Supports Kestrel weather meters via bluetooth, including new 5x00 family (for Android 4.3 and newer)!
Support Kestrel DROP environmental data loggers (for Android 4.3 and newer)!
Supports Weatherflow WEATHERmeter (for Android 4.3 and newer)!
Supports WeatherFlow WINDmeter (has a problems with some devices. Weatherflow was informed about this issues).
Trajectory validation (truing) by speed or ballistic coefficient.
Can measure incline angle with phone camera
Can get current weather from internet
