Take a break, look up and discover a new world right above you!

Written from the ground up for any amateur or even the more experienced sky gazer, Sat Seeker brings pin point accuracy to satellite watching. Locate the current position of the International Space Station and see exactly when it will pass overhead for any point on earth! When you've witnessed a visible pass of the ISS it's an experience you will want to repeat again and again. With Sat Seeker not only will you be able to find all the passes that are coming up over the coming days or weeks but you'll also be able to see the exact position of the space station for every instant during a pass.

Can I see it?
Most people will have no problems seeing the ISS when it makes a visible pass with nothing more than the naked eye. You're looking for a bright object that looks just like a star moving steadily across the sky. Sat Seeker gives clear indication of which passes are visible. Be patient, due to the rotation of the earth sometimes your location won't have a visible pass for a week or two but they will come around.

Not sure where to look?
Use Sat Seeker's built in augmented-reality mode to show the satellite pass overlaid on top of your phone's camera. Just hold your phone to the horizon and look around. In this mode you will see the exact path of the space station as it will look from the point where you are standing. The visible and non-visible sections of each pass are clearly marked by the colouring of the pass line on your screen.

The sky's the limit!
• Pinpoint ISS pass times down to the second.
• Watch visible passes with just the naked eye.
• Find either visible or non-visible passes with ease.
• Show ISS position overlaid on your camera view.

Out of this world.
• Show the satellite position and precise viewing angles for any point during a pass.
• Find passes for any location on earth.
• Uses built in gyroscope and compass to show exactly where your device is pointing.
• Automatically retrieves updated TLEs to ensure pass predictions stay accurate.

Best application to view the ISS

I have tried numerous programs to view the space station and this is the best. It isn't a program to see the stars or planets, it is to see the ISS fly across the sky.

Notifications can be set to let you know when a pass is happening. I've seen the ISS fly over hundreds of times and I still get excited each time.

Great app

I would give this app 5 stars, I would. But I have a funny suggestion for the developer... - When the notification of a fly by alerts the user it makes a jet noise or fly-by noise. The space station is in space.. So it would not be making that noise! Hahah other than that, awesome app.


Had to cancel, could not turn off when not in use.
