Caan anybody recommend an Android app which records position and
altitude, and later you can add that data to the exif of JPEGs and
RAWs?


Any trail logger that saves (or exports) date in .kml, .kmz, .gpx,
.log (NMEA sentences) should do the trick.Â* But do check that it
supports altitude, esp. NMEA files as many do not record altitude.

Google Play is the source.
This looks promising:

I use a German product called "Trails" on my iPhone - alas not
available for Android.


I'm using O.I.Share for the E-M1 II but it doesn't record the
altitude.


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 the other photos. (tedious).

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.Â* 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.Â* (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.



I do it the easy way. I take a snap of the location with my iPhone. All
relevant information is recorded.


Yes - I do that too. A manual step, but in some ways simpler than
running weird geotag apps.
