Default Geotagging app

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?

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

I don't have an app suggestion, but a possible idea:
If you don't find it you might be able to rig up
something with Google maps, which does offer
altitude.
Sample:

Enter this URL into a browser and you'll get back the
elevation (in meters) for Boulder, CO. The text is
easily parsed and the whole thing can be automated.

maps.googleapis.com/maps/api/elevation/json?locations=40.014985,-105.270545

That request returns this:

{
"results" : [
{
"elevation" : 1623.978393554688,
"location" : {
"lat" : 40.014985,
"lng" : -105.270545
},
"resolution" : 19.08790397644043
}
],
"status" : "OK"
}

But then of course there's the issue of auto-entering it
into your image files.

Any trail logger that saves (or exports) date in .kml, .kmz, .gpx, .log
(NMEA sentences) should do the trick. 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.

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. 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 * 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.

That sounds like the hard way given what the OP wants to do.

The OP's issue is automated tagging his Oly phots. Similar to me
tagging my SLR phots. (Though I usually use an independent GPS recorder
I can also use my iPhone for that).

If you record GPS continuously then tagging any number of photos after
the fact takes a minute to set up and a few seconds to execute using a
tool like exiftool or any one of a variety of GUI based tools.

exiftool -geotag=GPS_20171103_162238.log -overwrite_original_in_place
-geosync=-4:00:00 *.dng

(Just need to navigate to the folder containing the dng's before
executing the command. I keep a "template" of the command in a text
file so I just need to paste that into terminal, modify the gps file
name and let 'er rip).

Recording the position in a single shot is a fine backup, but pretty
tedious if you have 50 - 100 photos to tag afterwards.

That is useful - I've used exiftool before, but this is either new or I
have not noticed this feature...

What particular app do *you* use for recording travel geo points?

Many years.

I use either a dedicated GPS recorder (AMOD) or my iPhone or both.

On the iPhone I can use several apps but have tended to use Trails - as
I mentioned in my first reply to the OP.

That well may be. For a lot of images it would be a PITA. I do
geotagging primarily so I can come back to the location, and/or let my
friends know the location. I started doing that after I saw some great
potential shots, but was unable to stop. I have been unable to locate
that area on Google, and I was unable to transfer the locations from my
car's GPS.
A few weeks ago we were just going for a ride, looking for possible fall
foliage shots. I quickly realized that I was a few days early, so I took
some iPhone shots, for general location purposes only.

Unfortunately we had a Nor'easter, that blew away the leaves. But at
lease I can look in that area next year.

Agreed. If geotagging all of my images was important to me, I would
attach a GPS gadget to my camera.
