DivotTracker is a MacOS X application which allows you to record your golfing performance, and calculate your handicap index.


Version 0.9 (July 31, '07) - Adds basic printing support and re-sizable window. 

Version 0.51 (June 22, '07) - Initial release. I'm sure some bugs slipped through, please e-mail me if you find any.


DivotTracker attempts to comply with USGA standards for handicap calculation.

See this page for an overview of handicap calculations in DivorTracker. 

System Requirements:
Mac OS X 10.2 or newer, Intel or PowerPC


What's New in version 0.9: 

  • Print support.  Print list of rounds and current handicap.
  • Re-sizable main window.

Quick Tips: 

  • Before adding scores from rounds, enter the course data (Name, Rating, Slope) in the "Manage Courses" window.  Once the course data is entered, it can be quickly selected for each round played at that course.
  • If your courses do not use slope ratings, entering a slope of 113 is equivalent to no slope factor.
  • To handle multiple tee boxes, add tee selection to course name.  For example: "Arcadia Bluffs (Blue)". 

Handicap Calculations:

  • I have attempted to comply with all USGA standards for calculating handicaps.  This includes using the correct number of significant digits and rounding rules.   DivotTracker handicap calculations are just for personal use, and are not official.   A USGA sanctioned organization is needed for an official handicap usable in competition.
  • Differential?  - In the listing of rounds played, DivotTracker shows a "Differential" for each round played.  This number is part of the handicap calculation, but is usually not shown in other applications.  It is basically your score, adjusted with the course rating and slope of the course.  So, it gives a good indication of your true performance, offering a way to compare rounds on vastly different courses -- and to see exactly what each round contributes to your handicap. 
  • Five rounds are needed to calculate a handicap.  With less than five rounds input, your handicap will show as "0.0" .
  • With five rounds input, the one best round is used for handicap calculation.  The number of rounds used increases until twenty rounds are entered.  For twenty rounds or more, your 10 best rounds of the last twenty played are used.
  • Since only net score is input, it is up the the player to take Equitable Stroke Control into account.  For example, a player with handicap of 9 or lower can take a maximum of a double bogey on a hole.
