An archery toolbox for calculating marks for sights with manufacturer scales.

Various in-app purchases unlock access to premium program features.

The app uses a configuration created from the user's sight definition and desired arrow parameters.

It has similar features and flexibility as the desktop app available from Pinwheel Software.

It is the only marks app that provides optimal sight marks from a trajectory calculated with a "through the lens" angle to target view. All other apps (and rangefinders) use simple trig or goofy device edge schemes.

You can use two or three shot in marks to calculate your actual arrow velocity.

You can modify all marks in the calculated mark list by changing a single anchor mark.

Flexible, Accurate, Unique.
