Twixt Time is a specialized tool designed to track the accuracy of watches and clocks over time. By capturing precisely timed snapshots of their dials and communicating with NTP timeservers, Twixt Time calculates and displays the accuracy of each timepiece. Users can easily add new snapshots daily to monitor the timekeeping performance. The app provides information on the most recent rate, overall average rate, and cumulative gain or loss for each watch or clock.

Twixt Time supports various dial configurations, including hour & minute hands with central seconds, hour & minute hands with seconds displayed in a subdial, and hour & minute hands only. Additionally, the app is compatible with GMT watches, chronograph watches, and watches with offset seconds hands, offering a versatile solution for tracking precision.
