I'm wondering if there's some way to use RM maps on the apple watch.
What I'm looking for is:

• ability to show/mark waypoints and handle the import/export of them (GPX or USR).
• use in some way ReefMaster depth maps (would they be vectors, passing via the garmin exporting process and maybe by handling them with GPSmapedit, or shaded relief rasters/flat maps with MBTiles or other better formats for the purpose

I'm not too familiar with what Apple watch can display, but assume there must be some mapping apps out there able to display waypoints etc?
