GoISSWatch ISS Tracking is an iPhone application developed by GoSoftWorks Development Co. It falls under the category of Education & Reference and is available for free.

This app offers real-time tracking of the International Space Station (ISS) and provides pass predictions for when and where to actually see the space station pass overhead. With features like a 3D globe tracking view, map tracking view, and overhead sky view, users can easily visualize the current location of the ISS. The app also provides ISS information and a high-resolution image, along with links to NASA and Wikipedia for further exploration.

GoISSWatch ISS Tracking offers time-lapse control, allowing users to control the speed of the tracking animation. Additionally, users can zoom in on the map and sky views, and use motion control for the sky view. The app supports both landscape and portrait orientations, making it convenient for users to view the ISS from any angle.

One of the standout features of this app is its pass predictions. Users can receive visible and 24-hour pass predictions, and even set up pass alert notifications to never miss a sighting. The app also supports easy setup using iOS location or a city list.

It's worth noting that GoISSWatch ISS Tracking requires occasional data network or WiFi access to update satellite orbital data. However, once the data has been updated, users can track satellites, including the ISS, in real-time without an active internet connection.

For a comprehensive satellite tracking experience, users can also check out the developer's GoSatWatch app, which tracks hundreds of satellites, including the International Space Station, without any ads.
