This app allows you to visually learn about the different phases of the moon depending on the positions of the moon, the Earth, and the Sun.
The app has undergone a major overhaul to improve its features!
Why does the moon have different phases?
Why does the height of the Sun change depending on the season?
These diagrams provide easy answers to these questions!
You can intuitively grasp the positions of the Sun, the Earth, and the moon through overhead and celestial sphere diagrams!
What are the positions of the Sun and the moon during a full moon?
Where is the Sun when the waning crescent transits the meridian?
You can answer these questions by turning the dial and checking their positions!
※The size and distance of celestial objects are not drawn to scale but exaggerated for easier understanding.
※For easier understanding, the Earth's orbit is made circular instead of elliptic while the inclination of the moon's orbit has been omitted.
Can be 2 screens.

Good start, usable, but still needs more development
It is a good learning tool to start a lunar discussion, however, kids get pretty bored just watching the app make the orbits. To improve, they need to allow the user to select dates and/or times to predict and tie information together. Also, a zoom function would help.
This was pretty good through the big LED projector.
So, this is a good beginning, and I used it in my 7th grade classroom, but to be more powerful than one day...keep going this could be really good.
Excellent visual representation of moon-sun relationship
I agree with other viewers, it has room for more improvement. There is a similar app for Android users. This one lets Apple get a glimpse too, but perhaps needs to be more flexible and I would like to see the Western Hemisphere in the free version, please.
