If they are connected to D-Bus, you will see a NameOwnerChanged signal
indicating that the owner of their bus name changed from a non-empty
value to the empty string.

If they are not, and when you say "app" you really mean "systemd unit",
then this is a question about systemd, which D-Bus developers do not
have any special knowledge about.
