You have plenty of apps. You are still the one connecting them.
The thermostat app knows the temperature. The camera app knows the driveway. The calendar knows your week, and the inbox knows who is waiting on you. None of them knows that the furnace at the lake house hasn't run since last night and you are arriving Friday.
So the connecting is left to you: checking, remembering, chasing. In a busy household, or a business where you personally dispatch, approve and follow up, that load adds up.
Aria's job is to carry some of it for you.
