USER REVIEWS

❝ The developer is very responsive to app suggestions. I suggested adding a config option so the ISS wouldn't pulse when viewing. He responded that it would be implemented, and within a few days, a new version was available with that option. Much easier to watch now.❞

❝ If you’ve never seen the space station fly overhead, you really need this app.❞

❝ Spectacular app. Brings ISS into the home. Absolutely marvelous.❞

❝ Absolutely awesome!❞

❝ Having used various other ISS trackers over the years that have since been left behind due to the lack of development, it’s been great seeing the attention that’s gone into this one. Clean, easy-to-use UI, which doesn’t take long to navigate your way through all of the different options. I love the fact there’s a complimentary Apple Watch App, too, which makes looking out for passes really easy! Good work, thank you!❞

❝ Absolutely a brilliant app. We're having a run of about 10 days with the ISS overhead. This app gives you good details of what time and what direction it will be traveling. 10/10❞

❝ Very nice update. New icons for the Apple Watch app, the globe looks good on iPhone and iPad, and the James Webb background is spectacular. In my opinion, still by far the best of the ISS apps!❞

❝ 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. Tech support is immediate, personal, and efficient. Among my many, many apps, this one is at the very top. Five stars for sure!❞

❝ The most beautiful App I have downloaded.❞

❝ My Fave! I like that I get the specifics of where it will come up and which direction it will be heading. I also do the 'spot the station' notifications, but this app gives me more potential sightings. There is a lot of other information here, too.❞

❝ Just bought this app and would like to say a massive thank you, it's an amazing app and very interesting.❞

❝ Absolutely fantastic! I’ve followed the ISS for many years now. This app is by far the most accurate and a pleasure to use.❞

❝ Excellent Application. The new version with the globe is magnificent! Thanks to the designers.❞

❝ A lot of details. Thanks to the developer. Great attention to detail. It's fun to play with the app. Keep it up.❞

❝ This app works great. It gives accurate pass predictions and is fast and easy to use. Looking forward to their next app.❞

❝ This app is fabulous for tracking the ISS. This app is really functional and very simple to operate and understand. I was really impressed with the tracking and info.❞

❝ This is a fantastic app for keeping tabs on when you can view the ISS. I had alerts set that popped up in my calendar with the perfect amount of lead time—without any real thinking or planning on my part. This app makes it easy.❞

❝ I’ve been using this app for about 3 years now, and have found it to be very precise and excellent.❞

❝ Love it! It's great. It's really accurate.❞

❝ Provides useful and accurate information and easy to use. I have used this many times to view the ISS. I like the extra information on each astronaut and adds to the enjoyment of seeing and knowing the specialities of the astronauts. Thanks again for providing this.❞

❝ Love this app. Great for tracking the ISS. You can not only see times visible in your area but also ratings of 1 to 4 stars on how visible it will be.❞

❝ The best app available to track the International Space Station. I recommend it to all my friends!❞

❝The most beautiful app I have downloaded.❞
