## What is Sat Seeker ISS Tracker?

** Featured on ITV's This Morning **
** Top 15 app in UK App Store **
** No.1 Reference app in UK App Store **

Did you know that several times every day a space craft the size of a football field passes overhead at over 17,000mph?

…and that it’s easily seen with your own eyes with no special equipment?

…and that Sat Seeker will show you exactly when you can see it and will notify you of passes precisely for you and your location?

If you didn’t know about one or more of the above what are you waiting for?! The International Space Station is the largest man made satellite ever built and it can regularly be easily seen from your home! All you need are cloudless skies when a visible pass occurs and Sat Seeker to show you when and where to look. 

Keeping track of when the space station is visible isn’t practical to do manually. Throughout the year for most inhabited areas of earth there will be periods of a week or two when the space station will be visible daily. In between these visible ‘runs’ there can be a break of visible passes for a period of several weeks. You don’t want to have to manually monitor when passes are due to occur next so Sat Seeker calculates precise pass details based on your location and then notifies you automatically. Shortly before an upcoming pass Sat Seeker displays a notification so you will never miss a visible pass if you fail to check upcoming pass times.

When you've witnessed a visible pass of the ISS it's an experience you will want to repeat again and again. Don’t waste any time. Get the app now and see when the next pass is happening where you are. It could be this evening

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 very bright star moving steadily across the sky. Sat Seeker gives a clear indication of which passes are visible. Be patient, due to changes in the earth’s position and the ISS orbit sometimes your location won't have a visible pass for a week or two but they will come back around.

Features
—————
* Automatic notifications of passes as they are about to begin
* Current ISS position and orbital path overlaid on world map
* Precise pass timings for your location
* Precise details of ISS positioning throughout each pass including when the visible portion begins and ends
* Augmented reality view for each pass. Tap the camera button on the pass details screen to load the AR view. Point the phone towards to horizon to see the ISS position and path overlaid over the camera view

Are you still reading? If you’ve made it this far then maybe you still have doubts…would it help if I said that on rare occasions you can also see ISS passes followed shortly by visiting spacecraft such as the the SpaceX Dragon? Visible occurrences of these passes are much rarer but we try to announce these on our social media channels. Follow/like us there too!

### 4/5 — Has anyone tried paying the 99p donation?

*2025-09-12, version 2.2.6*

Have tried many times and all that happens is the icon around the payment symbol just rotates

### 5/5 — I miss this app

*2024-12-20*

When this app is working, it is the best app available hands-down. Is anybody else having problems besides myself? Please fix this wonderful App!

### 5/5 — Amateur astronomer

*2024-09-25*

This is my first time using this app. It is real easy to use. I do a lot of astronomy outreach and this will help me show people how to find the ISS ! I will recommend it to my friends and family and the places I do outreach. Thank you !

### 4/5 — Please fix!!!

*2024-02-23*

I LOVE this app! So accurate and makes it so easy to find the ISS. But it has stopped working over the last few months. It just hangs and does nothing when you open it. PLEASE FIX!!!  iPhone 13, iOS 17.2.1.

### 5/5 — Stopped working

*2023-12-10*

This is by far my favorite app for tracking space station. Nothing comes close to this app. However, it hasn’t been working lately. Not sure what to do but would love to get it back working again! Please fix!

### 4/5 — Becoming undependable

*2023-09-19*

This used to be great for locating the ISS with the ability see exactly where in the sky it is, but lately I go in and the app won't load or work AT ALL. PLEASE FIX IT!!!! Thanks!

### 1/5 — Crashing each time the app tries to open

*2023-09-03, version 2.2.6*

I love this app but suddenly it won’t load and crashes each time…very annoying … shame

### 5/5 — Sat Seeker

*2023-05-28, version 2.2.4*

It’s great to watch!

### 4/5 — Love the app

*2022-11-04, version 2.2.4*

But it’s keeps not working only recently , is it still supported ?

### 5/5 — Great but could improve

*2022-05-23, version 2.2.4*

I have used this app a lot and it's great but adding an option for notifications a certain point above the horizon would make it awesome. I can't see the passes under about 10 degrees and am constantly disappointed when I think there is a visible pass but it's not visible for me.
