The official British Marine app, River Thames Guide, has been updated and will roll out from the respective app stores over the next day or so (Note: users of the full Android version will need to download the updated version from the app support site).

New Features for this version:
River Thames Journey Planner results can be overlaid (in yellow highlight) on the interactive map.
Use what3words to tell emergency services, friends or family where you are to within three metres.

Lock detail popups do now popup when tapped on the Locks page (as they do on the interactive map).
Grammar improved in the Journey Planner results.

If you don't have the app yet download links are provided on the support site.

Ideas or comments welcome from all users (via the About pager in the app).
