Siri and Shortcuts Say “Start Tabata with Roundwork” and the workout begins. Pause, resume and skip a phase work through Siri too. Everything is ready in the Shortcuts app, for automations and the Action button. Control from the Lock Screen The Live Activity now has buttons to pause and to skip the phase, right on the Lock Screen and in the Dynamic Island. On Apple Watch they show up in the Smart Stack. Halfway cue If you like, the app gives a short cue halfway through every work phase, with a tap of its own on Apple Watch. Ideal for switching hands or sides. Turn it on in Settings under Sound.
