Bare bones GPS logger for iOS?

Hello. I am looking for a barebones gps track logger with poi/waypoint marking for ios. Something like gpsLogger II on Blackberry. I should be able to export .gpx files for uploading to osm and for working with JOSM.

Most of the products on ios are too fancy and resource hungry. Any suggestions?
