This is really cool and nicely made! Congratulations! I'm assuming you don't have years of programming experience (feel free to correct me!) which makes it even more impressive when looking at the things you got right. This include the idea/functionality, layout, source and that cool Moon animation!

I would suggest improving a couple of things:

1) defaults:

  a) some people don't like pickers (especially this "modern" hour then time thingy) and would like to just click the "Calculate" button. I think that the value that you have already set in the picker is good enough for most.

  b) eliminates issues where the value is not visible in the GUI but it is set in the program. Right now, if you open the picker and click on "Cancel" (or outside the picker) without selecting a time, the input does not show a value but you can click on the "Calculate" button and it calculates using the default value.

2) tables of data: if there's not much data in a table, like in the one the recommended sleep time, do consider copying the data instead of rendering the image. It makes the data searchable (accessibility is important) and, usually, saves an additional request for that resource.

Definitely continue! You're on the right path.
