About

SCT Calculator 3

Features
Read full description

The SCT Calculator is a utility for AKC Agility Judges to easily calculate and record their Standard Course Times (SCTs) at a judging event. The app allows you to enter in distances measured either in feet or in yards (the app assumes that numbers larger than 220 are designated as feet measurements). Quickly select the class type (either Standard or Jumpers With Weaves) and the class level (either Premier, Master, Open, Novice or ISC) and press the calculate button to update the onscreen display of your SCTs. Use the Settings button to set your email address, the name of the club, and any calibration adjustments for your wheel. If you don't supply both an actual length and a measured length, the wheel calibration will not be taken into account when you enter in your measured course distances. Pressing the Email Button will automatically send the calculations to your supplied email address (using the email app on your device) for permanent record keeping. If you select the ISC class, you can also record which level (L1 thru L3) the class is for. This version of the app includes the latest rule changes announced by AKC that went into effect on July 1, 2024.
