Nicely done, handy little app. I'm thinking that a useful update would be to add a compass to the display too as there's a lot of room left on the screen. Just a suggestion. Great app though if this is something you need.

Just what I needed

I need to know the Julian date for spacecraft mission activities and it's a pain to calculate but this takes all the pain away. Brilliant!

Nice simple app

One comment though... LST data implies accuracy to the second but the seconds field just tracks wall clock time which is a little misleading.
