Out of all the apps I have downloaded, I wanted to use sky map to look at the stars while on holiday. Only while away the days that I remembered to look up to the sky above, clouds stopped me. The app always boots up and can pinpoint stars and I have used it several times to show how good the android g1 phone is in comparison to others. The ability of the app to search and to show any stars that you see in the distance is exvellent.
