Hi,
One of my issues is that my wife does not enjoy the night sky viewing with me, not so much for the night sky itself but as she is deaf and sign language as first language she can't talk to me (boring). I found this app that I hope to be useful, and not just for me.

I think it may be good for observers to voice dictate their viewing which could be done with handsfree set or something.
I dont know how well it works but I tried some small tests. I hope that I will be able to talk at night to my wife and she can read what I am saying.
