Solar Coaster vs EclipseX

Solar Coaster provides accurate position, time, motion and eclipse information for Earth's nearest star, Sol, our Sun, and nearest celestial body, Luna, our Moon. Information includes 3D movement graphs, upcoming eclipses and their circumstances, rise and set times, positions, distances and velocities, moon phase, illumination and crescent rotation. Solar Coaster automatically updates its state every minute, or you can examine minutes randomly. The simulation uses a local horizontal coordinate system when displaying information, which essentially means that your current position is the center of the Universe and all calculated values are relative to you. Sun and Moon positions are also available in equatorial coordinates. Solar Coaster stores enough onboard astronomical data to keep it running through the year 2100 AD, which means that all calculations can be performed locally without the need of a network connection — useful while in the wild chasing an eclipse. Algorithms are accurate at all longitudes, and latitudes between -61° south and +60° north (roughly speaking, locations outside the Polar regions). Of course, you must have Location Services enabled and allow Solar Coaster to access your position for accurate simulation results, and to properly detect eclipses visible at your location. You can also allow Notification Center to keep you informed when those eclipses will occur. Solar Coaster comes in various flavors: for iOS a native App; and for macOS a native App, Screen Saver and Web App.

EclipseX is a fast, offline-friendly catalog of solar and lunar eclipses. Browse upcoming events, check visibility for your current location, and open a trajectory map to explore the path. Highlights: 1. My Location: Detects your country/continent and shows eclipses likely visible where you are. 2. Trajectory Map: Full-screen map with centerline overlay and quick links to details. 3. Upcoming List: Clean list with type icons (Total/Annular/Hybrid/Partial/Penumbral). 4. Search & Filter: Filter by year or by kind (solar / lunar). 5. Region Aware: See where each eclipse can be viewed (continents & countries). 6. Details View: Key facts like date (UTC), magnitude, Saros, max duration, notes, and source link. 7. Lightweight & Private: No account. Location is used only to compute visibility on device. Notes 1. Centerline overlays are provided for key upcoming eclipses and will expand over time. 2. Ad-supported (Google AdMob) to keep the app free. 3. No login required. Works on iPhone and iPad.
