Sputnik!

Buena app.

Excellent application. It includes notifications for the ISS and satellites. Minor issues: - Notifications are not working for me. iOS 7 4s - Recalibration should be triggered on every app launch to increase accuracy

Muy útil para ver eventos en el cielo.

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!!!

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.

This app provides the user with top quality viewing information .

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 It continues to report Outdated.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”.

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.

I really like this app
