AstraView vs Apphemeride Precise Astronomy

AstraView transforms stargazing from guesswork into discovery. Whether you're a curious beginner with binoculars or an experienced observer with a telescope, AstraView tells you exactly what to look at and when. SMART RECOMMENDATIONS, NOT JUST DATA Every night, AstraView analyzes your specific situation—where you are, what equipment you have, what's blocking your view, and what you're interested in—then ranks celestial objects so you know what's truly worth observing. No more wondering if that galaxy is visible from your backyard or whether your telescope can resolve that nebula. YOUR HORIZON MATTERS Other apps assume a perfect 360-degree view. AstraView lets you capture your actual horizon using AR or a quick manual setup. Trees blocking the east? House to the south? AstraView accounts for it, only recommending objects you can actually see from where you stand. POINT AND DISCOVER Activate AR mode and point your iPhone at the sky. The interactive star map shows exactly what's above you in real-time as you move your device. Scrub through time to see where objects will be later tonight. WEATHER BUILT FOR ASTRONOMY Cloud cover is the enemy of stargazing. AstraView provides astronomy-specific weather forecasts that identify your best observing windows—those precious clear-sky periods when conditions are right. MULTIPLE SITES, ONE APP Save different observing locations with their own equipment setups and horizon profiles. Compare visibility across sites to choose where to observe tonight. KEY FEATURES • Personalized nightly recommendations based on your location and equipment • Horizon-aware visibility that accounts for trees, buildings, and terrain • Augmented reality star map with time scrubbing • Astronomy weather forecasts with clear-sky window identification • Moon phase tracking with sky brightness impact • 10,000+ celestial objects including planets, stars, nebulae, galaxies, and clusters • Personal observing list with multi-location visibility tracking • Equipment profiles for naked eye, binoculars, and telescopes • Planetary conjunction and meteor shower alerts • Home screen widgets and daily notification forecasts PRICING AstraView is free to download with full feature access. The free tier includes 1 observing location with 1 vantage point. AstraView Pro (one-time purchase) unlocks unlimited observing locations and unlimited vantage points per location. Pro purchases are tied to your Apple ID and restore automatically on new devices. Family Sharing is supported.

Track the sky from any location Apphemeride helps you follow current sky events, spot future events early, and explore past, present, and future phenomena. Run location-based calculations for your current location or any place on Earth. Scan for special configurations of planets, moons, and stars, as well as meteor showers. Find out when an event can be observed or photographed, display it on the sky map, or jump straight to the objects involved. The expanded sky map now offers multiple orientation modes, constellations, more than 9,000 stars, and a visibility filter. Create personal watchlists for your favorite celestial bodies and the astronomical values that matter to you. Set alerts for when a selected value reaches, exceeds, or drops below your threshold. Explore detailed data for the Sun, Moon, planets, Pluto, Chiron, and more than 9,000 stars. Depending on the celestial body, examine rise, meridian transit, and set times, azimuth and altitude, coordinates, twilight, illumination, phase, brightness, angular diameter, distances, and rates of change. View planet positions in the sky or solar system and analyze solar and lunar eclipses with maps and visual simulations. Use the Horizon Tracker to study how the Sun, Moon, or planets move across your local horizon. Compare azimuth and altitude over a day, month, or year and plan observations for a particular viewing direction. Where the sky is darkest, there is often no signal. Apphemeride still works: all astronomical calculations and observation tools are available offline—at remote observing sites, in the desert, or out at sea. Only street and address search requires an internet connection. Customize values, units, formats, and precision to match the way you work. Apphemeride is not a simple star finder, but a comprehensive tool for astronomy enthusiasts, astrophotographers, travelers, and anyone who wants to understand movements in the sky precisely. New users can try all astronomy features free for three days. Afterwards, a one-time in-app purchase unlocks them permanently. Anyone who bought Apphemeride before the transition automatically keeps permanent access.
