From the developer:
ArcheryTune lets you configure key elements of your bow. You will see the ideal image of your target and be able to change, for instance, the size and power of the lens, the size of the scope dot or fiber, the distance between your eye and the lens, etc. You have at your disposal English target faces, field target faces, and few images of 2D-animals for natural shooting.
