No sir, that was not the intention nor the impression that Apple gave us at the Keynote.I think Apple just wanted to offer a basic app for the mental wellbeing aspect .
Their Journal app was to have access to certain very personal otherwise unavailable APIs that DayOne or any other Journaling app couldn't since it's not Apple branded.
I still have yet to see these benefits, nor have I seen any of the promised integration with the Apple Shortcuts app.
