Is there a way for an app on a watch (Gear S3) to write to a file directly on a connected phone, without a server app on the phone? Ideally I would like to access a database, inserting records, just as if the db was locally on the watch, but actually on the phone. Of course (as hinted above), the watch and phone would have to be connected.

Any ideas?

TIA
