This is the easiest way to spot the station.
ISS Detector will tell you when and where to look for the ISS. You get an alarm a few minutes before a pass. You will never miss it. ISS Detector will also check if the weather conditions are right. A clear sky is perfect for spotting. The Chinese space station Tiangong 2 are also tracked.

Extensions will enhance the functionality of ISS Detector. With an in-app purchase you can add many famous satellites and amateur radio satellites. See the Hubble space telescope, rocket bodies, Vanguard 1 and many bright satellites.

Love this app

As an amateur radio operator I find this app very useful. So useful, in fact, that I have had it on several phones and tablets over the years. It's great for sitting out in the yard with a nice cigar and enjoying the night sky.

The only improvement that I can think of would be to add the uplink/downlink frequencies and modes for the amateur satellites. If I had that information this would be the only app that I use for satellites.

ISS Detector

This is a great app with all the info on the ISS and the Chinese Space Station. However, it frequently fails to boot up and just the little wheel is left spinning and no info on the screen other than settings and the ad at the bottom. I do not know why the app does this and have tried different maneuvers to get it to boot up without success. Would give it 5 stars if it were not for this issue. Has happened multiple times.

Best ISS App

I pretty much live by this app! I love being able to add flyovers to my Calendar and the 10 minuet notifications so I don’t miss it. I’ve turned many friends and neighbors onto this app also, and we enjoy watching the flyover together. Also love the Info it gives in real time and the radar view is accurate and easy to understand. Thank you for this Great App!!
