Strelok. Ballistic calculator for Android

Product snapshot

Strelok Ballistic Calculator is a field-oriented app used by precision and long-range shooters. It computes bullet trajectories using detailed physics models and supports both metric and imperial measurements. Shooters input rifle and cartridge parameters to receive precise scope adjustment values and holdover data.

Core capabilities

• Multiple drag models are available, including common standards and custom profiles, to match a wide range of ammunition.
• Environmental and ballistic effects such as spin drift and gyroscopic stability are modeled so results reflect real-world conditions.
• Visual reticle overlays show wind holds and range holdovers on-screen, letting users plan shots without changing scope turrets.
• Users can enter detailed rifle and cartridge specifications to generate accurate correction tables and aiming points.

User interface and visual aids

The app provides selectable reticles that overlay wind and distance corrections directly on the aiming view. This visual approach helps shooters quickly determine holdovers and windage without dialing turrets, making it particularly useful during dynamic or time-sensitive shooting scenarios.

Versions, limits, and migration

• The premium edition receives regular updates and includes a broader feature set and reticle library.
• The free edition is more limited: it supports fewer reticles, restricts users to a small number of rifle profiles (ten), and lacks some modern features present in the paid release.
• Moving from the free app to the paid version requires manually exporting and importing rifle configurations, which adds an extra step during the upgrade.

Who should consider it

For hobbyists and occasional range users the free build may suffice. Serious long-range shooters, competition participants, and professionals will benefit from upgrading to the paid edition for expanded functionality, up-to-date features, and a larger reticle selection.

Final thoughts

Strelok is a powerful trajectory tool that combines advanced drag modelling, environmental compensation, and visual reticle support. While the paid tier delivers the fullest experience, the limited free version may feel outdated to demanding users—so upgrading to the full product is recommended for anyone relying on consistently precise long-range performance.
