Strelok Pro

A NEW GENERATION OF BALLISTICS

Strelok Pro is a brand-new ballistic calculator built from the ground up for modern iPhone and Android devices. This is a new application with an all-new codebase, modern interface, AI-powered tools, live weather integration, and continuous feature updates.

Built for hunters, PRS competitors, and long-range shooters, Strelok Pro combines professional-grade ballistic calculations with the world's first AI Range Assistant.

★ RANGE AI — A FIRST IN BALLISTIC CALCULATORS

Ask questions in plain language:
• "6.5 Creedmoor at 800 yards, 10 mph wind from 3 o'clock"
• "Best bullet for PRS competition?"
• "My groups are vertical at 600 yards"

Range AI provides holdovers, load recommendations, and shooting guidance using GPT with sensible rate limits.

★ FEEDBACK & SUPPORT

We're actively improving Strelok Pro and would love to hear from you. If you have feedback, feature requests, bug reports, or any questions, email us anytime at feedback@strelokpro.com. We read every email and will do our best to respond to everyone.

Always confirm your zero and verify your dope at the range. Ballistic calculations are a starting point—not a substitute for real-world verification.

Important: Strelok Pro is a completely new application, built from the ground up with an original codebase and a modern feature set. It is not an update to or a continuation of any previous application that may have been available on the Google Play Store, and it is not affiliated with, endorsed by, or associated with any previous application, developer, or publisher that has used the name "Strelok" or similar branding.

Recent changes:
- Wind direction is now labelled as a clock angle off your bore (0 = headwind, 90 = from your right), so a full-value crosswind is no longer entered as a headwind by mistake.
- Target distance now goes down to 5 yards for airgun and rimfire shooters, with a correct firing solution at short range.
- A cleaner reticle view: the scope picture is no longer overlaid with text.
