It's Kept Up With Newer Satellite Technology

For several years, I enjoyed using Satellite! to reliably predict the appearance of Iridium flares from the now non-existent Iridium satellites. After they disappeared I thought the app had outlived its usefulness. I was wrong. I soon found that I could now use Satellite! to view the International Space Station, the Chinese Space Station Tiangong, the Hubble Telescope, and now even the newer Starlink Satellites with the same pinpoint accuracy! It’s like Satellite! has reinvented itself! Great app!!!

Used to be great but has stopped working

I used to use this quite often and it was really handy to have on my phone.

Recently though the app has stopped working and just says “No Sightings” for all the categories. I’ve tried uninstalling and reinstalling to no avail the app now just seems to be broken/useless.

Changing screens

I get very frustrated that when I press to get details of sighting I get into that stupid trace line and can’t get out.

Great free app for find ISS!

I have had this out for years! Back when it tracked iridium flares. Now it tracks the ISS, Chinese station, and Hubble. I love this app. It shows the magnitudes and device orientation from your location. Although I do miss the iridium flares.

Top quality app for your celestial viewing.

This app provides the user with top quality viewing information .

Was good, now refuses to update satellite data. Also, strange error message.

This used to be one of my favorite ISS spotting apps. However, it now refuses to update the satellite data on iPads and iPhones alike, from iOS 12-16 and iPad OS 15-16. Going to Settings and tapping on Update does NOTHING. It continues to report Outdated. And, yes, WiFi is on and working. The Sputnik! app is the latest version. On an iPad 9, iOS 16.5.1(c), it alerts me: “Warning Satellite data has never been downloaded”, but does not load it automatically as it is supposed to — and used to. The Update button doesn't work there, either. On an iPhone SE, iOS 15.7.7, when I select any of the Satellite Sightings choices, it reports: “ERROR. Null check operator used on a null value”.

The app stopped working on my iPhone. I did the update and it’s not working.

Good app

This is a good app for finding satellites especially if you are at a place where there is no or very little light pollution.

What’s “Enters Earth’s shadow” mean?

This app needs more reference information. Are satellites visible when they ENTER Earth’s shadow? Or when they LEAVE Earth’s shadow?
Why would I want to look for a satellite that rises at 10° and then enters the shadow in a few seconds?
Following this app faithfully for two years, I have been able to see less than half of what is shown on the schedule. This “shadow” mystery might be the reason.

Also, the feature where you need to turn your device sideways or landscape to see the satellite path or hear a beeping countdown needs to be explained somewhere.

Finally, the feature to show device orientation does not seem to correspond to the actual elevation. In the settings, it says to adjust the orientation by 90° if you are recording video, but not why, or what that means.

Great

I really like this app

Précision assez précis

Parfois des erreurs !

I preferred the old design

The new one looks like an app for kids

Nice work

Great work in the app. Needs to have a filter. I don’t want to see all the things less than 30 degrees off the horizon due to trees around my house and there is no way to quickly filter out the stuff I won’t be able to see. Maybe a filter for magnitude would be nice as well

Iridium flares ended

The last Iridium satellites deorbited in December 2019. There are nones left to track. Tracking others still works fine.

Coolest app

I just tracked ISS in the first try ,thanks whoever made this app

Really Useful

I guess this is quite basic in what it does - no fancy animations etc - but what it does it’s excels at.

It’s my first port of call to find out what time I can expect to see visible satellites from my locality

Brilliant

My one and only ISS spotting app.

Easy to use and free.

Thanks

Starlink

It would be nice if you could be able to track Starlink. This is a great app and works great.
