ISS Detector vs NASA Eyes

ISS Detector helps users find visible International Space Station passes and predict satellite passes for their location. For each upcoming ISS pass, it gives the local start time, direction, highest altitude, and duration, and can notify users minutes before the pass begins. It checks the local forecast and indicates when clouds may prevent a sighting. Premium features add tracking for Starlink, Hubble, rocket bodies, planets, comets, and amateur radio satellites; amateur radio tracking includes transmitter information and Doppler shift calculations. Users can share sightings on social media. ISS Detector says it combines information from NASA, Heavens-Above, the Minor Planet Center, and yr.no weather. It is listed for Android, iOS, macOS, and web. The free plan includes ads and in-app purchases; ISS Detector Pro costs $17.99, paid once and includes all extensions with no ads. Its privacy policy says location calculations happen on-device and precise location is not stored on the maker’s servers. Google Play says data can’t be deleted.

NASA Eyes is a free suite of interactive 3D applications for exploring NASA data and imagery in a web browser. Eyes on the Solar System lets users move among planets, moons, asteroids, comets, and spacecraft in a simulated view spanning 1950 to 2050. Eyes on Asteroids follows more than 30,000 asteroids near Earth's orbit and identifies the next five closest approaches. Earth views present data on topics including carbon dioxide, ozone, sea level, weather, precipitation, and soil moisture. Eyes on Exoplanets offers exploration of more than 5,500 confirmed systems, with filters for planet type, detection method, and observatory. DSN Now refreshes Deep Space Network station information every five seconds; Mars Relay Network visualizes communications involving Mars orbiters, landers, and rovers. NASA says the browser apps work on internet-connected devices with a modern browser, including phones, tablets, computers, and Linux systems. NASA also provides guidance for museum and educational use, website embeds, and kiosk setups. Older downloadable editions still run but are no longer supported.
