What's new

Version 1.1 · Nov 7, 2026

What's new in 1.1: • Your timer settings and selected preset are now remembered between launches. • A 10-second warning bell now sounds before each round starts, as well as before it ends. • Ending a workout early now saves it to Apple Health with the rounds you completed and the calories burned. • iPhone Duo support, including tabletop mode: half-fold the phone and the clock fills the top half with the controls on the bottom.
