Hi Alex
Android is an operating system used on many smartphones. Of course it is easy to set up a spreadsheet as you describe - the apps I am talking about have a built in nautical almanac so they take care of the sight in one go - you only provide date time body sextant altitude and height of eye.
You say download the almanac - is there an online copy available to download?

Zvi,
I am not exactly sure what "Android" means, but I use sometimes for the same purpose
my small laptop. It takes few minutes to make a spread sheet which will reduce
your sights momentarily, if at the place where you observe there is no
Internet connection.
Before you do observations, you will have to enter your co-ordinates, GHA for the whole hour,
declination,
your watch correction and your dip correction.
You can also download the Almanac, and then you don't have to worry about GHA and declination.
Then you enter the sextant readings and time by your watch, and it tells you
everything you need.
Alex.
