Athlon Ballistics is the free companion app for Athlon Optics shooters. Use it with your Athlon chronograph, with Athlon thermal scopes and clip-ons, or on its own as a ballistic calculator.

CHRONOGRAPH
• Connects to your Athlon chronograph over Bluetooth, automatically when it is near.
• Live screen: see the velocity of every shot as you fire, with average, extreme spread (ES), standard deviation (SD) and energy.
• Name each session, add notes, and link it to a rifle and a bullet.
• Compare and merge sessions.
• Sessions sync to your account and come back on a new phone.
• Export sessions to a spreadsheet and share them.
• Update the chronograph firmware from the app.

BALLISTIC CALCULATOR
• Firing solutions with G1 and G7 drag models.
• A library of factory cartridges and bullets. Add your own bullet with its BC, weight and length.
• Rifle profiles with sight height, twist rate and zero range.
• Live local weather for the solution, or enter the conditions yourself.
• Ballistic charts with your own ranges and steps. Export them to a spreadsheet.

ATHLON RETICLES

ATHLON THERMAL SCOPES
• Connect to supported Athlon thermal scopes and clip-ons over Wi-Fi, including the new Athlon DCM.
• Live view from the scope; take photos and videos and save them to your phone.
