Before each competitive Curling game, both teams need to play two "Last Stone Draws" each. The distance is measured either from the centre of the house to the nearest point of the stone or, if the stone covers the centre, from two points 2ft away from the centre.
The app calculates the real distance from the centre to the centre of the stone in both cases, using the official formula from the World Curling Federation WCF.
Values can be entered for up to six sheets.
Data entry can either be in metrics (cm and/or mm) or in imperial (inches and 1/100 of inches).
