Have you seen the International Space Station? You can actually see it in the night sky.
See the Starlink satellite train with the Famous Objects (included in the Filter menu).

If you like space or astronomy, you will like this ISS tracker app.

ISS Detector Pro includes the functionality of ISS Detector (free) with all the Extensions and no ads.

You can see more in the night sky:
Radio Amateur Satellites
Track dozens of ham and weather satellites. Includes transmitter frequencies and Doppler shift calculations.

Famous Objects
Track Hubble, X-37B, Fitsat, Tiangong, Rocket bodies and more. Most are visible.

Comets and Planets
Track comets as they come closer to earth and become bright enough to see.

ISS Detector Pro will tell you when and where to look for the International Space Station or Iridium flares. You get an alarm a few minutes before a pass. You will never miss a pass of the International Space Station and you will never miss the bright flashes of the iridium communication satellites. ISS Detector will also check if the weather conditions are right. A clear sky is perfect for spotting.

• Share sightings on social media.

ISS Detector combines data from Nasa, Heavens-above.com, minorplanetcenter.net and weather from yr.no.

I've been a long-time user and even paid for the expansion packs to unlock the Pro version. However, out of nowhere today, the app suddenly refused to open, asking me to pay $6.49 again or subscribe to Google Play Pass. This is disappointing, especially since I’ve already paid for full access. Please address this issue promptly, as it affects loyal users who have already invested in the app.

The greatest, most data rich, easy to use sky watching app I use daily. To learn and see how much is going on just above our heads and we don't need a telescope to see what's going on is just a revalation and opens up the rest of what's up there. It's too bad it seems that a competitor or someone has a bone to pick as I see so many inaccurate reviews perhaps because they are too lazy to learn to use it, if so then they probably won't take the time to walk outside and look into the sky.

This app has been critical to me in the process of learning to use satellites for amateur radio. Not just the ISS! Absolutely worth the "pro" version purchase, and then some! One feature I'd like to see added: filter based on max elevation for an approach. I live between 2 hills. Frequent passes of 5 about degrees aren't viable for me. So for example, I'd like to be able to filter for passes greater than 25 degrees elevation. Great app!! Thanks!

Update Feb 2020: app hasn't properly notified me of an ISS event in six months. Uninstall - reinstall - rebuild phone - alter settings - nothing works. Any ideas? It was great, but for the last six months at least, notifications don't work on my Samsung S5 or S7, Marshmallow or Neugut (?) Neither myself or tech support can solve it. Must be a conflict with another app, but which one - no idea

This app was good YEARS AGO. Now it just fustrates me. The gyroscope is inaccurate. It spins around like a clock (even when you don't move). Satellites never appear when or where displayed. It was simple and accurate years ago. I stopped using it, but recently purchased it for my new android s10e totally inaccurate and a waist of time.

It's alright I quess, it does pretty much what it's serpose to but you can't take screen shots with the app and you can't download the feed either, which it says it does have a live feed but i haven't seen it yet, it's always been a recording, and maybe you could explain how you use the compass to, that wouldn't hurt, other than that you can track a lot space stuff so it dose do what it's serpose to but it could do more like being able to download the feed if ever go's live, so yeah,, average.

Try to update my previous message regarding app crashes. Apparently the developer created a fix today for the issue. I have downloaded and installed the fix and the application is working perfectly, exactly as I would expect. Well worth the price.

One of the most incredible Apps you will ever own. Its all the reviews say it is. Best App for tracking Amateur Radio Satalites. All the data you need to know is at your fingertips. No need to go to Amsat to get frequencies or offsets if you would like to listen to OSCARS. Dont hesitate.. buy the App, its worth the money and it helps the developer, who is doing an incredible job.. enjoy the night sky.
