Apphemeride

Ephemeris: Sky & Navigation

$49.00 · Designed for iPad. Not verified for macOS.

Explore eclipses, Moon motion, planet illumination, coordinates, and horizon events with a precise ephemeris app for astronomy and navigation. Explore eclipses, sky motion, coordinates, and location-based astronomy with Apphemeride, a precise ephemeris app for astronomy and navigation enthusiasts. Have you ever wondered when the next solar or lunar eclipse will happen at your location, where a solar eclipse will be visible, or what the sky will look like during the event? Apphemeride helps you study these questions visually, with maps, simulations, and detailed astronomical calculations. Follow the apparent motion of the Sun, Moon, planets, and stars. Compare rise, transit, and set events. Examine twilight, illumination, declination, ecliptic coordinates, and horizon geometry. See how the Moon's path changes through the seasons, why the full Moon rides differently in winter and summer, and how sky orientation changes between places such as Germany, Singapore, Australia, or New York. Apphemeride is built for people who like to ask precise questions: - When does the Sun or Moon rise, transit, and set? - Where will the next eclipse be visible? - How will an eclipse look from a selected location? - How does the sky change when I compare two places on Earth? - Why does the Moon appear flipped or tilted in different hemispheres? - How bright is twilight at a specific time and location? - How do planets change phase, illumination, and position? Use Apphemeride for observation planning, travel, education, navigation practice, and pure curiosity about celestial mechanics. It is not just a table of numbers. It connects astronomical data with visual tools so you can understand how the sky behaves over time and across Earth. A professional tool for skywatchers, eclipse chasers, travelers, educators, and anyone fascinated by the geometry of the heavens.
