Billard Aiming Calculator app for iPhone and iPad
Would you like to improve your pool game? If so, this will be the App for you. Position the target-, object- and cueball on the billard table. The App computes immediately the cut angle and shows the aiming view on the object ball! The tangent line shows you the path in the case of a stun shot.
With the cueball to ghostball distance and the ghostball to objectball overlap you can estimate the rolling distance of the cueball after hitting the objectball dependent on your stroke speed.
