Spot the Station is NASA’s mobile app for finding International Space Station viewing opportunities. It is designed for the general public and runs on iOS and Android phones and tablets. The app covers most inhabited locations worldwide, combining current station tracking with upcoming sighting lists, local timing information, and alerts. It is a focused choice for people who want to see the ISS, rather than a broad astronomy app for stars, planets, or deep-sky objects.

The published Free plan includes International Space Station tracking, viewing schedules and alerts, and an augmented-reality sky view. Its real-time map shows the station’s current position, while sighting details include duration, height, directions, and local time. Personalized alerts can be based on location and timing, and push notifications help identify upcoming passes. The camera-overlay view adds trajectory lines, with separate 2D and 3D station-location views for users who prefer a map-based perspective.

Spot the Station also includes NASA space-station resources and a blog, giving the app a learning-content element alongside its viewing tools. Offline support is limited: previously downloaded schedules and scheduled notifications may work without a connection, while real-time tracking requires internet access. Choose it if your goal is free, location-aware ISS spotting with alerts and visual guidance. Choose a broader astronomy app instead if you need coverage of multiple celestial objects or a wider observing toolkit.
