Anyone using Navionics?? Looks like the app needs a bit more work on the Android version. Navionics kills the battery on the HTC Desire. It puts the GPS on full-time unlike other Applications which have settings to pulse the GPS off and on at user selected intervals. When the app is dormant it still leaves the GPS on, as it is impossible to exit the App you continually drain the battery until you kill the App (using App killer) or use the widget to switch of the GPS. This is not very good. It seems possible to record an "empty" track (ie. turn tracking on, then turn it off without going anywhere). This then becomes an entry in your list of tracks which is difficult to delete. In order to delete it you need to display the track on the screen and "press" on the track to get the track details and the delete facility, as the track is empty there is nothing to "press" on. There is no edit available on the recorded tracks. Using it as a "log" on the boat over the weekend it recorded a nice track etc. for the trip and then proceeded to continue recording the track all the way home in the car (because I forgot to switch tracking off). When veiwing the track and sharing it on the facebook/navionics sharing facility, you then get the trip details including the drive home. It would be nice to be able to cut segments from the track. Pinch zoom has not been implemented. Hope this helps someone.
