Does anyone know if there is a way to create an Agenda watch face, complication, or know someone who has done so? Would like to have my calendar events show in a section on my watch face or the ability to view calendar events in another view.
Not as far as I know.
Creator Pro (subscription required) allows launchers for apps. I am not subscribed, but guess that the default calendar app can be launched in this way.
You can use creator pro and create a button to activate the calendar.
