Have you seen the International Space Station? It is visible with the naked eye!
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.

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 Starlink satellite trains, Hubble space telescope, rocket bodies, Vanguard 1 and many bright satellites.

Available Extensions (in-app purchase):
Radio Amateur Satellites: Track dozens of ham and weather satellites.
Starlink and Famous Objects: Track Starlink satellite trains, Hubble Space Telescope, rocket bodies, bright satellites and more.

What’s New

Version 2.4.1

Added rotator control to the Extension. With this you can remote control your telescope or antenna rotator. You can find more information in the help section.

Nice looking up. Many things to improve.

A lot of work still needs to be done:
Keep screen awake during sighting. There is nothing more annoying then the phone locking down in middle of qso.
Also, notifications are temperamental. Sometimes you get no notifications for any of the passes then suddenly it comes up and then off it goes again losing some of the best high passes. It usually works over night when asleep waking up to tons of notifications you don’t need. :)
So, maybe need to look for another app but I’d prefer to pay a bit extra and get proper functionality.
Good design and very well done in respect of interface and layout.

Doesn’t Appear to be Working

I have installed and purchased the additional items. Unfortunately, when I tap on any icon a Large information window opens in the middle of the screen. This window cannot be closed or moved out of the way on my iPad and I am not able to use the app.
The developer has answered my email almost instantly and this is being worked on. It might just be the latest update of iOsPad 13.2 that’s causing it, I think.

Great with Wi-fi, no good if you’re out of data range.

Great whilst online, but unfortunately if you’re away from Wi-fi or mobile data signal it can’t detect anything. Would definitely be 5 stars if you could load even 24hrs worth of predictions in and use those as backup if no mobile data was available.
