For years I have logged all my astronomical observations on printouts, made in excel. Carefully arranging all the columns so that it would fit on one page.
Then in the field, every time I was fiddling around with red lights, tables and pencils ('cause ballpoints won't write well on damp paper). And then, the next morning I'd take my notes and I'd copy everything over to my logging software. Sometimes, the stuff I wrote was unintelligeble, since I tried to write it with half frozen fingers and almost no light...
But, now I'm past all that!
I made a logging app for Android!
