GPSTrack allows you to use the GPS receiver in your iPhone or iPad to show your current location and create a log of your travels.
With iOS 4, GPSTrack can track your location while in the background, so you can continue to use your iPhone for other tasks. (Continued use of GPS running in the background can dramatically decrease battery life. Background support requires the iPhone 3GS, iPhone 4, or iPad.)
When recording a track, GPSTrack can show a map with your path, updated in real-time.
Saved tracks can be exported via e-mail in GPX and KML formats, useful if you want to geotag photos from a camera that doesn't have GPS support.
