A Tide Height data field would be awesome

Sadly it seems tricky to do this well...

There are a few restrictions with Data Fields. As I understand it:

1. They cannot communicate with an iOS/Android companion app
   1.1 More specifically, a mobile app cannot adjust the data field's Toybox.Properties (Otherwise the mobile app could just push data to a property on a regular basis...)
2. They can issue communication requests (as a background process), but I want this to work when I don't have my phone on me (going for a run)
3. They may be able to access persisted content (waypoints, etc), so it might be possible to get data in that way (but hacky) Just checked this - it is only available to apps, music, and widgets :(
4. Garmin also has "Complications" that would do exactly what we want if I wanted the tide data on a watch face... Which, honestly, would be pretty great too?

Options are as follows:

1. Create a new app that provides all the data fields I care about for running (basically re-build the "Run" activity app), that also does the web API requests to collect tides and cache that data.
2. Possibly use the System.Intent mechanism to launch a Run from the BCTides app and pass in valid tide data
   1.1 Is there a way to query this data from a data field???
3. Unsatisfying, but easiest: Keep BCTides as widget, and use hot keys during an activity to launch the watch face, and from there the widgets...

Complications require api version 4.2.0 or later..
