Introducing the 4DOF® Multi HUD | Multi HUD Overview

4DOF® Ballistic Calculator
Ideal for precise long range calculations using select low-drag precision bullets, the Hornady 4DOF Ballistic Calculator provides trajectory solutions based on projectile Drag Coefficient (not ballistic coefficient) along with the exact physical modeling of the projectile and its mass and aerodynamic properties. Additionally, it calculates the vertical shift a bullet experiences as it encounters a crosswind; referred to as aerodynamic jump.

My app says it wants to do a new update in the app but it says it cant. And on google play it does not say it needs an update
Any ideas?
