About this app

Looking up at the night sky and seeing the International Space Station (ISS) glide overhead is a breathtaking experience. With ISS Detector, you can easily track and locate the ISS using just your smartphone.

The ISS tracker app for all mobile platforms can help you to see the ISS.

ISS Detector notifies you a few minutes before the ISS is due to pass overhead, ensuring you never miss the chance to see it. The app also checks for clear weather conditions, so you can have the best possible viewing experience.

But that's not all - with in-app purchases, you can enhance the functionality of ISS Detector even further. The Radio Amateur Satellites extension lets you track dozens of ham and weather satellites, complete with transmitter information and real-time Doppler frequencies. The Starlink and Famous Objects extension allows you to track famous objects like SpaceX's Starlink satellite trains, the Hubble Space Telescope, rocket bodies, and other bright satellites.

Finally, the Comets and Planets extension lets you track all planets and comets as they become visible in the night sky. Whether you're a space enthusiast or just looking for a unique and awe-inspiring experience, ISS Detector is the perfect app for discovering the wonders of the cosmos.

Fantastic app. Far above and beyond all other satellite tracking apps. You can watch ads to access Pro Features for a few days, I will be buying the Pro Version for sure. You can track many satellites not just the ISS. If you're using it to hear them on the radio, make sure to un-check the "visible passes only" option so it will alert you EVERY time its in range. I can't overstate how much I love this app!! Get it!!

I used to love this app. I bought all of the extension so I could see everything. Recently, notifications have stopped working and when I open it it is only showing the ISS. I need to refresh it to see all of the extensions I paid for. The extensions then work for maybe one more day, then they stop. It seems to have started after the most recent update. I have sent emails, but no response. Sure wish you would fix this issue.

I finally looked into the short easy training. Now that i understand that it all means, i know exactly where to look for the ISSor what ever else i am interested in. Stuff i never knew about before this app. I actually pulled out my cell phone and took a few photos, hoping for at least a dot. Imagine my excitement when i saw a dot, zoomed in and actually have a photo of the iss even with the solar wings and all! I look up every time the sky is clear and some thats not so clear, nust to be sure.
