With iOS 12 Apple has released the new Shortcut app. This allows to speed up often recurring workflows.
One such workflow for me is starting a workout with RowingCoach. So I created an exemplary shortcut which enables “Do Not Disturb” for the next hours, starts the music and launches RowingCoach for an outdoor workout at the same time. Just add a Siri command word like “Rowing” and the next time you say “Hey Siri, Rowing” all that happens automatically!
You can download it here (on your iPhone) and adapt it to your personal preferences.
