Loving the stars and planets ⭐️⭐️⭐️⭐️⭐️


I have always wanted to be able to identify the stars in the night sky. Never managed to understand the star maps and charts, couldn’t make sense of them.
Now I can launch the app wherever I am, day or night and make sense of the amazing heavens above me.
Thank you App developers - loving the stars and planets

Notification won’t go away


I am leaving this here because I cannot find where I can contact the app developer. The app is good and very useful to find out what you are looking at however I have a notification symbol that will not go away. It’s been there for a week or so now. I think it must be a bug in the app. Can anyone help?

Memorise the Southern Cross!


Had this a few years ago. Pretty good for free. Downloaded it again last month to find my way round the stars in South Africa. compass only worked below the horizon, so if you’re below the equator, find the Southern Cross first!
