Satellite Watcher vs SpaceStationAR LITE

This app tracks the 150 brightest man-made objects in space, which can be seen by the human eye. Use it to see the time and location such objects can be seen. It also lets you record when you saw each satellite. You can also use this app to explore all 9000 stars visible to the human eye, as well as major constellations. Educational notes are displayed for satellites, constellations and well-known stars. Some of the app's features: * Preview mode lets you browse through future satellite passes, displaying the magnitude, path and time the satellite will appear * Real-Time mode shows you what is in the sky now, with the current location, magnitude and path for each satellite. If multiple satellites are in the sky, it shows them all simultaneously * Tap on a satellite's name to view detailed information including country of origin, launch date, magnitude (brightness), and more * Tap on a constellation's name to view its educational notes * The app lets you keep track of which satellites you've seen and when. You can tell it you see a satellite now, or enter a past sighting * The device detects your location automatically, but you can also enter the latitude and longitude yourself, or your U.S. zip code * Choose which satellite you want to scan for, or all satellites * Choose how many days into the future to scan for satellites, up to 30 days * Choose the minimum elevation for a satellites to be shown * Choose the minimum magnitude (brightness) for a satellites to be shown * Works offline (you should go online to download satellite data once every couple of days) * Displays weather warnings if clouds will be present (in the U.S. only) * Works on iPhone and iPad If you like science and astronomy, you will have great fun spotting satellites! All you need is a clear night with no moon. For best results, choose a location away from city lights. In the beginning, focus on the brighter satellites passing directly overhead. Satellites are visible after sunset (for about an hour) and before sunrise (also for about an hour) when the sky is dark and satellites reflect the sun's light. This is a great educational activity for kids.

SpaceStationAR is an augmented reality (AR) application that simulates the visibility of satellites in the night sky. With SpaceStationAR, you can easily spot the brilliant International Space Station, spectacular Starlink Trains, and various satellites at the forefront of space exploration with your own eyes. As your iPhone or iPad camera captures the scenery around you, SpaceStationAR overlays passes of the International Space Station, the Starlink Train (a group of Starlink satellites), and the Chinese Space Station onto the actual scenery. You can also use the app to find bright stars, galaxies, spacecrafts like Voyager 1 and Voyager 2, and even see the direction of major cities beyond the ground. SpaceStationAR also indicates the positions of geostationary satellites, making it a valuable tool for antenna installation. You can easily access satellite orbits on maps in addition to the AR views. The "Calendar" tab displays events like upcoming satellite passes and rocket launches within the next two weeks. You can choose a pass from the list and simulate it in AR. Apple Watch app and "Today" widget are also available. They show simple lists of satellites' passes. LITE version has some restrictions. AR prediction stops 30 minutes before the passes. Full version without Ads and with the sky chat view is available on the store. http://itunes.apple.com/app/torisat/id361194118?mt=8 List of Features * AR simulation of satellite passes overlaid on real landscapes * Display of stars, galaxies, black holes, planetary probes, satellites, and world cities in AR (Visibility can be customized by type) * Visualization of satellite passes on maps * Presentation of satellite orbits and current locations on a global map * Calendar listing satellite passes within the next two weeks * Support for newly launched satellites * Offline app usage * Satellite pass notifications: Set notification times from 15 minutes to 6 hours before the event for accurate alerts. (Please allow background location updates for precise notifications. Disabling this feature may lead to inaccurate notifications when traveling long distances with the app closed.)
