IIRC, on technical side Android have "intents". An app says to the system : "users wants to navigate to a place" and other apps can say "hey, i have a feature to navigate to a place". Apple don't provide such system and so you are blocked by what the source app wants to open. On Apple apps, it will open other apple apps, and on tier apps, it's up to what they want to open. Of course Apple have zero incentive to change this so I don't see it changing.
