A green speed calculator to calculate putting green speeds using a Stimpmeter.
This app has the following features:
Can be used to calculate green speeds using either a Stimpmeter Classic (any standard Stimpmeter) or Compact (USGA 2X slot can also be used).
Capable of calculating green speeds for both flat and sloping greens. For flat greens a simple averaging method is used, whereas for sloping greens the Brede equation is employed.
Enter up to three Stimpmeter measurements (in mm, cm, inches or feet) in both directions and the calculator will determine the green speed with a qualitative description.
Full instructions on how to use the calculator can be viewed by selecting "instructions" from the menu (the three dots at the top-right of the screen).
Provides warnings for invalid results - i.e. ball distances are too far apart.
Dark mode to improve screen readability where required.
More exciting features are planned in future updates.
