August 18, 2026
Seven new languages, more free rifles, and ballistic coefficients that carry their drag model everywhere. YOUR OWN RIFLE, FREE Build a rifle of your own and keep one a friend shares with you — on top of the three starter rifles the app comes with. SEVEN NEW LANGUAGES Greek, Finnish, Galician, Hebrew, Hungarian, Icelandic and Kazakh, fully translated throughout the app. COEFFICIENTS THAT KNOW THEIR DRAG MODEL Every ballistic coefficient now travels with the model it was measured against — G1 or G7 — through saved loads, the BC ladder, every tool and the solver itself. Loads you already saved are tagged automatically. VERIFIED CATALOG UPDATES Bullet and reticle data now arrives cryptographically signed, so every update you install is authentic. ALSO NEW Custom drag curves join Ballistics Pro, alongside accuracy refinements across the calculator, the reticle simulator and the atmosphere model.

Zima is a comprehensive ballistic solver designed for precision shooters, hunters, and handloaders. It calculates trajectories, provides atmospheric corrections, and offers advanced features for long-range accuracy.
Zima offers four primary solver models: 3DOF, 4DOF, 6DOF, and Pejsa. These models provide different levels of complexity and accuracy for ballistic calculations.
The app includes atmospheric corrections for G1/G7 drag models, ensuring accurate calculations under varying environmental conditions. Pro users gain access to even more advanced correction factors.
The free version of Zima provides a full ballistic calculator with trajectory tables, G1/G7 drag models, atmospheric corrections, up to 3 rifle profiles, and automatic iCloud Drive backup.
The one-time $19.99 Pro upgrade unlocks all four solver models, a 5,600+ bullet and cartridge database, 3D trajectory visualization, WEZ hit probability analysis, PDF range cards, and GPS target ranging.
No, Zima does not contain advertisements. The app is free to use with optional in-app purchases for its Pro features.
The latest version of Zima, 2.0.9, was released on June 17, 2026. The app is actively developed, with updates typically released to improve features and reliability.
Zima is available on Apple Watch and iPhone. Its features are optimized for these devices, including Home Screen widgets and Live Activities on compatible iPhones.
