Great App

This app has more features than I was expecting and they are great. The different features include Sky 2D, Sky 3D, Visibility, Globe, and options, where you can modify parts of the app to accommodate your use of it, and make it specific to you. The accurate and useful information is easy to access with the easy tabs at the bottom of the screen. The app uses the motion of your phone to create a 3D view of space. Further, in each planet is given its own description, where details are very specific and informative. There is nothing I would add!

great graphics, lots of fun!

I love the graphic for each planet - very nice! My favorite quick references are the Visibility List and the Spinning Globe. I love tilting it to see the Arctic or Antarctic in full. I check this app nearly every day!

My only wish is that they would include Pluto. (A so-called 'dwarf' planet is still a planet!) I realize it would be prohibitive to include all the 'dwarf' planets, but Pluto has a special place in the hearts of many people, worldwide. It would be very meaninful to me, and to others, if they would include it with the other planets in this app.

Good app with one rather significant flaw.


I have been using this app for years and have been pretty satisfied with it. It is pretty good for helping me figure out what I’m seeing in the night sky.

However, just found what I consider to be a significant flaw. I wanted to confirm my assessment of the Moon’s phase, viz. that it is about a day before the full Moon (i.e., a waxing gibbous). The app confirmed that tomorrow is the full Moon. However, it called tonight’s phase a waning gibbous. That is not correct. Waxing means growing. Waning means shrinking. Therefore, waxing phases come before the full Moon and waning phases come after.
