ISS Detector

ISS Detector makes stargazing easy and alerts you to ISS passes

ISS Detector turns casual skywatching into a surprisingly exciting habit. Its main mission is simple: tell you exactly when and where to look to see the International Space Station with the naked eye. In practice, it does this very well, wrapping orbital data, weather forecasts and clear notifications into a clean, user‑friendly interface.

The core screen shows upcoming passes in a concise list, with details like brightness, duration and elevation, so you can instantly see which events are worth stepping outside for. A built‑in compass and sky map help you orient yourself, making it easy even for beginners to locate the ISS as it sweeps across the sky. Timely alarms a few minutes before each pass mean you are far less likely to miss those short but spectacular flyovers.

One of the strongest features is the integration of local weather conditions. There is little point in an excellent pass hidden behind clouds, and ISS Detector clearly flags visibility based on cloud cover, saving you wasted trips into the cold.

For enthusiasts, the optional extensions unlock a lot more. You can track SpaceX Starlink trains, the Hubble Space Telescope, bright satellites and rocket bodies, or dive into amateur radio satellites with transmitter and Doppler shift information. Another pack adds planets and comets, so the app evolves from a single‑purpose tool into a compact personal observatory.

The interface is straightforward rather than flashy, and newcomers might need a few minutes to understand terms like magnitude or elevation, but built‑in explanations help. Overall, ISS Detector is a polished, reliable companion for anyone curious about what is flying over their head, from families watching their first ISS pass to serious satellite and radio hobbyists.
