WHAT USERS HAVE TO SAY

❝ This app offers as much hard information about the ISS and two other orbiting bodies as anyone could want, presented in a logical and easy to use manner. The watch app works perfectly on my old Watch 5, and the iPhone version is a pleasure to use scientifically and also visually. It offers additional features as well, such as real time video of the earth passing below the ISS which, frankly, is fun to watch. Tech support (needed the one time when I neglected to perform an update) is immediate, personal, and efficient. Among my many, many apps this one is at the very top. Five stars for sure!❞
