Bug fixes and improvements.

User reviews

Canโ€™t use it anymore

Used to be brilliant but now I canโ€™t work out how to search fir planets. So frustrating.

I'll stick to paper thanks.

Constellation boundaries make the overview cluttered and difficult to read. No ecliptic is a major omission I think. Zoom feature is nice, but if a closer view is needed, apps such as Star Walk are far superior. Good value for a few pennies, but not enough here to persuade me to give up my paper planisphere.

Just needs one fix

Downloaded this app for my astronomy lab. Cool app, everything is really clear, but the GPS function does not work. My phone's GPS is completely functional when I use maps, compass, etc., but not when I use this app. I'll point it clearly at one constellation and it will give me a completely different one. No complaints about anything else in the app. If this one fix is made, it'll be perfect.

This is great fun!

I play around with this with my grand kids. It teaches them while having fun. Great app

Great app!

This is a great app to play around with! Works great! I just wish I could choose a specific date to view directly instead of going hour by hour into the future or past. Other than that minor issue, I love it!
