Do you mean this one: "
Sky Voyager"???
My favourite GoSkywatch is
here.
FYI each app has an ID... and has an entry in the (
NON-SEARCHABLE!) Apple-App-shop Web interface.
(the APD 2010+2011 almanac is 380726782).
To search, one needs iTunes (bloatware, spyware, don't do it!). Every iPhone/iPad/IPod Touch has iTunes built-in. It is more convenient to search the App-shop on an apple mobile phone.
All non-
apple-mac-iTunes users need to use google.
In my opinion, mobile phone apps are great. Instant info in one's pocket.
