Calendar
What have I already said yes to?
Agreed, waiting or needing you.
Optional external calendar
Apple or Google, if you want.
Your full Calendar stays above. This simply adds a separate, read-only view beside the rest of your life.
Checking this device…
A view, not another source of truth.
The shared commitment remains authoritative. This calendar never accepts, changes or cancels anything for you, and it does not upload your address book.
