Precision ballistics infrastructure for every shooter, every platform, every distance.
One canonical engine powers Strelok Pro, Strelok Internal Ballistics and Strelok for Desktop — solving external and internal ballistics to the mil.
Strelok Pro is free to download — 3 rifles on the free tier. See all plans
One engine, every screen. Strelok Pro, Strelok Internal Ballistics and Strelok for Desktop — the same engine and the same account, from load development to the trigger press.
Describe the shot. Get the solution.
The only ballistic calculator with a natural-language assistant. Tell Range AI the cartridge, distance and wind — it fills the solver and reads back your holdover.
Try Range AIThe engine behind every solution. Four legacy solvers drifted apart. We rebuilt one canonical Rust core — and every product speaks to it.

Why “Strelok”?
Blame a late-night gaming session. Our developers were deep in S.T.A.L.K.E.R. — the cult shooter set in the Chernobyl Zone — whose legendary marksman is named Strelok, Russian for “shooter.” When it came time to name a ballistics app built by people who take every shot seriously (virtual ones included), nothing else came close. The Zone gave us the name; the math is all ours.
