Best thing to do with the kids!


I am hooked on watching for the ISS. Last night we watched on the app as the ISS flew over the Pacific and crossed over the Mexican/Southern California border. We live in central KS so that was our cue. We went outside- parents, grandparents, and the kids and watched in total fascination as the ISS went shooting over our heads right on time- the most brilliant satellite you’ll ever see, almost like a comet. It was a 3 star rated view so it was awesome. We cud see it visually and map it on the app til it got to the Canadian border approximately and it faded out. A huge thumbs up for this app. And thank you that it’s free! Especially neat cuz the kids were every bit as fascinated as the next two generations! Fun to experience it together!

I SS Spotter


I love this app because it gives me very accurate information about the tracking of the International Space Station. It also lets me set up alarms to notify me when the ISS will be visible from my location, making this app very useful to the novice astronomer.
The best thing is that it is free for all to use. I like it so much that I made a donation to the developer and I hope that they will have many further improvements to this app.

“That’s so cool…”


It never gets old, watching the best of humanity’s efforts zipping past, plain as you please. Oohs and aahs from first timers. Even when it’s mostly cloudy, no stars are apparent, and there’s only a sliver of maybe-open sky, the ISS can gleam right through and this app will have you looking up at the right time and direction. With a clear sky, it’s a spectacle.

I’ve used the app for years and it’s always stable. Five stars. Étoiles haute, y’all!
