As a stopgap you could snap a photo with the Android camera and (if
properly set) that data would be saved in the snap for later transfer to

Pretty much any "trail logger" can be used for what you want to do and
usually the "tagging" can be made automated in post process. You do
need to know the offset from "real time" to your camera's time in order
to do that - no big deal using exiftool. (ie: your time zone and the
difference between "correct" time and the camera's time (unless you
sync'd it all before going out).
Important note: GPS altitude â‰* altitude above sea level of where you are
as the GPS ellipsoid is not referenced to sea level.
