About

iFox Observatory

Features
Read full description

iFox Observatory is a middle-school astronomy and space science lab for curious learners and homeschool families. It is not a wallpaper app, a space news app, or an image browser. It is a hands-on astronomy lab where learners can observe, adjust, compare, and explain what they see. The first version includes: • Moon Phase Lab: drag the Moon and watch lunar phases change • Orbit Simulator: adjust speed and distance to explore orbital motion • Eclipse Lab: arrange the Sun, Earth, and Moon to identify eclipse conditions • Sky Compass: learn azimuth, altitude, and observing direction • Light Spectrum Lab: adjust star temperature and observe color and spectrum changes Each lab includes an interactive visual model, user controls, instant feedback, short explanations, and clear learning goals. Core visuals are original procedural graphics and do not rely on external space images. iFox Observatory is part of the MindKey / iFox Family Learning science series. It helps learners do more than look at space. It helps them learn to explain it. No ads. No third-party tracking. Learning progress is stored locally on the device.
