1. A chronograph system, comprising:
a frame configured to removably couple to a barrel of a firearm;
at least two optical sensors attached to the frame, wherein a first optical sensor of the at least two optical sensors is separated from a second optical sensor of the at least two optical sensors by at least three inches, and wherein each optical sensor is configured to detect a projectile and record a timestamp as the projectile passes each respective optical sensor;
an accelerometer attached to the frame and configured to track an orientation of the barrel;
a processor module coupled to the frame and communicatively coupled to the at least two optical sensors and to the accelerometer; and
a mobile computing device configured to communicatively couple to the processor module;
wherein the processor module is configured to:
receive timestamps from the at least two optical sensors and the orientation of the barrel from the accelerometer;
use the timestamps corresponding with each projectile to determine a velocity of each projectile; and
send velocity data regarding the velocity of each projectile and the orientation of the barrel to the mobile computing device; and
wherein the mobile computing device is configured to:
receive the velocity data and the orientation of the barrel from the processor module;
display the velocity data to a user of the firearm; and
analyze the velocity data and the orientation of the barrel to aid the user in adjusting a scope of the firearm.
