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.
