Just what I need  but... Does exactly what I want it for - logging my position so I can geotag photos later - and uses very little battery to do it. It have one little quirk  though. If I have Location Services set to """"""""""""""""high accuracy""""""""""""""""  the app mostly appears to get locations from cellphone towers  not GPS  so you don't get altitude  heading etc. It only uses GPS if you set the phone to """""""""""""""" GPS only"""""""""""""""" (which stops other things working properly). This is not a problem for me at the moment  but it might be annoying at some point.""
