I was also asking about tracking a parcel on its route which is what
these parcel tracking apps do.

I doubt the apps do anything more than scrape the data from
royalmail, yodel, hermes etc websites ...

I believe these apps use official APIs, although in the past Royal Mail has
refused to provide the data.

You and I discussed some of this in this group last August in a thread called
"Royal Mail - Track and Trace fail". Since then I see lower value packages
getting tracked and wonder if a third-party app can now follow the progress
of a UK delivery by any courier.
