On the plus side, this app is very simple to use and does what it says on the tin - ie it logs your journey with GPS data and allows it to be exported by GPX for use in Google maps etc and to geotag photos.
It does have a few downsides compared to other ones I have tried, however. The main one is that if you lock the iPhone (and so turn off the screen) the app logging pauses. This means that the screen must always be on. My tests suggested that it would completely deplete the battery in about 2 hours (others typically last 5h plus). I also found it less able to acquire a GPS signal than other software I had tried (I don't know what this should be). It also crashed a few times and I had to reboot the iPhone.
In comparison to other apps, I would therefore have given this 2 stars except for one thing. Most other free apps are limited somehow - by number of tracks recorded, or logging time etc. This, however, is an unrestricted app. The battery issue seriously limits is usefulness in my view, but its free and great for short trips or just recording your location for geo-tagging so who's to complain? (3 stars = good in my book)
