About this app

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, comets, planets and many bright satellites.

Available Extensions (in-app purchase):

Radio Amateur Satellites: Track dozens of ham and weather satellites. Transmitter information and real-time Doppler frequencies.

Starlink and Famous Objects: Track SpaceX Starlink satellite trains, Hubble Space Telescope, rocket bodies, bright satellites and more.

Comets and Planets: Track all planets. And track comets as they come closer to earth and become bright enough to see.

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!!

One of the most accurate, if not THE most accurate out of all the ISS tracker apps. There's nothing I don't like about this app. The countdown until next visibility as well as the countdown until you lose visibility is spot on. The interactive star map is also a nice touch. The alerts are very helpful. The ads don't bother me. Great work!! Highly recommended downloading this!

I'm impressed with it. This is a well designed, user-friendly app. Ads are pretty much optional and they don't interfere when you're trying to use it. No badly timed pop-up ads to worry about. It been very accurate too as far as the location and timing of objects and what to expect when viewing it. Things like brightness and when/where it disappears completely. This app also turned me on to iridium flares. I never knew about them before. The flares are rare but I did manage to see two of them.
