Amazing AstroCalculation-App
Response from developer
Thank you very much for your feedback! More exciting features will be coming soon, and I hope you’ll enjoy them as well.

This app provides precise astronomical data for sky analysis, including eclipses, Moon motion, and planetary positions. It offers location-based calculations and visual tools to understand celestial events and their visibility.
1.1.0
August 9, 2026
Version 1.1.0 expands Apphemeride with more ways to personalize and plan your observations. • New celestial objects: Pluto, Chiron, and more than 9,000 stars are now available in the app. • Expanded sky map: Use different orientation modes, constellations, the expanded star catalog, and a visibility filter. • Personal watchlists: Track your favorite celestial bodies and the astronomical values that matter to you. • Custom alerts: Get notified when a selected astronomical value reaches, exceeds, or drops below a threshold you set. • Versatile event scanners: Find out when special configurations of planets, moons, and stars, as well as meteor showers, can be observed or photographed from your location. • Direct access: Show detected events on the sky map or jump straight to the celestial objects involved. • Minor fixes also improve precision and the user experience.

Apphemeride can track solar and lunar eclipses, the motion of the Moon, and the positions of planets. It provides detailed data on rise and set times, transits, and horizon events for these celestial bodies.
The app uses your location to perform precise, location-based calculations for celestial events, rather than relying on generic tables. This allows for accurate analysis of how the Sun, Moon, and planets move across your local horizon.
Yes, Apphemeride offers visual simulations for solar and lunar eclipses, complete with maps. You can also see where an eclipse will be visible and how it will look from a selected place.
Apphemeride offers detailed data on relative planet positions, orientation, illumination, phase angle, magnitude, angular size, and distance. It also includes specific information on Jupiter's Galilean moons and Saturn's moon system.
Apphemeride is described as a premium tool for serious skywatchers and those who want to understand celestial mechanics with accurate calculations. It is not a simple star finder but a focused ephemeris app.
No, Apphemeride is ad-free. The application does not contain advertisements, allowing for an uninterrupted user experience.
Apphemeride is available for iPhone and iPad. It supports these Apple devices, leveraging their capabilities for precise astronomical analysis.
The app was last updated on July 4, 2026, with version 1.0.2. This indicates regular maintenance and potential feature additions by the developer.
