Fantastic and accurate! (December 14, 2017) NEW QUESTION: (March 19, 2020) I have this app and I see there is a PRO version; what's the difference? I can't tell... I did (apparently) purchase the add on filter pack and I can see the Amateur Satellites & Frequencies, Famous Object, Moon & Planets, Comets, Iridium Satellites (now defunct). I'm really pleased with this app. Easy to track the Amateur Sat's, the altitude and azimuth angles are dead on the money! When needed I can use the alarm / notification feature to remind me when something's coming.

Wahoo wish i could give a million stars, but i just bought the full version instead for $5 and some change. This app has never failed me when it comes to sightings. The compass and trajectories are always right on. Rely on this app more than NASA notifications. It just gives you all you need in one app! Highly recommend to anyone and everyone, buy the full version too. Get out there and start gazing at the heavens people! Now excuse me! My next ISS sighting is in 8 mns and i must prepare!

Most amazing app! I downloaded this after struggling with the Nasa text notification as I know the ISS is here to observe for a limited time. This app is nothing short of amazing! The calculations , viewing times and orientation in the sky have been spot on. I has an average user have no clue how much time and effort went into creating this application but it has far exceeded my expectations in all facets. Plus there are so many othet celestial objects you can track for additional fees. Bravo!

I've used this app a few days for tracking amateur radio satellites. For the few satellites I have tracked so far, this app has proven to be very useful and accurate. It's ease of use has greatly simplified the whole process, but at the same time, it provides more than adequate information. This is accomplished through intuitive & efficient design interface. I also greatly appreciated the temporary unlock feature, to test drive all the bells and whistles before purchase. This was done in a fair & convenient manner. I hope other devs would follow suit. I am picky about which apps I choose to spend money on, and this one was well worth the price. Great job! Verizon / Motorola G6

Great graphic design. Does what it says as far as tracking the orbit of ISS. I have not had the opportunity to test its accuracy of sighting ISS yet, ISS making a pass and me being outside haven't aligned very well. Which of course is in no way the apps fault. I would like to see a option to set a minimum elevation though. I live in a city anything under 30° is unviewable. And more notification options including permanently silence would be nice. But the app worth installing for ISS spotting.

I used to love this app. I bought all of the extension so I could see everything. Recently, notifications have stopped working and when I open it it is only showing the ISS. I need to refresh it to see all of the extensions I paid for. The extensions then work for maybe one more day, then they stop. It seems to have started after the most recent update. I have sent emails, but no response. Sure wish you would fix this issue.

I recently purchased the full add-on package (Combo Pack) to be able to track other objects (i.e. Starlink satellites). It worked for about a week and now only shows me the ISS. And yes, the Starlink service is enabled (switched ON). Update: I have both set location manually and restarted my phone without success. 2nd Update: I was able to get it running properly by clearing the app cache and restarting the app. I hope this is not something I will have to do often, but is good to know how.

Fantastic app. Far above and beyond all other satellite tracking apps. You can watch ads to access Pro Features for a few days, I will be buying the Pro Version for sure. You can track many satellites not just the ISS. If you're using it to hear them on the radio, make sure to un-check the "visible passes only" option so it will alert you EVERY time its in range. I can't overstate how much I love this app!! Get it!!

When my notification alarm goes off, the list only shows the next visible pass, not the one that is about to happen. The notification today only showed the track data/ pass for tomorrow, not the one for today. My alarm is set for 15 minute warning. What is going on? EDIT: The developer contacted me in only 1 day. Great support! Suggested that I change the Threshold magnitude from "all" to a different setting. I set it to -2 and it fixed it. Thanks for the help!

Absolutely great app!! Easy and fun to use. The app let me know exactly when the Space Station was overhead, and there it was easily observable at 9:22 PM, 250 miles up and supposedly moving at 17,000 miles/hr. We watched it for 3 minutes until it disappeared into the night side of the earth. Great shots from the ISS as well. My family loved it and all wanted the app. Thank you to the developers!

One of the most accurate, if not THE most accurate out of all the ISS tracker apps. There's nothing I don't like about this app. The countdown until next visibility as well as the countdown until you lose visibility is spot on. The interactive star map is also a nice touch. The alerts are very helpful. The ads don't bother me. Great work!! Highly recommended downloading this!

I'm impressed with it. This is a well designed, user-friendly app. Ads are pretty much optional and they don't interfere when you're trying to use it. No badly timed pop-up ads to worry about. It been very accurate too as far as the location and timing of objects and what to expect when viewing it. Things like brightness and when/where it disappears completely. This app also turned me on to iridium flares. I never knew about them before. The flares are rare but I did manage to see two of them.

I enjoy viewing the ISS when it's visible overhead. Want to use it for the ham radio, but it lists several that have long been *decommissioned*. Gotta do extra research to find out if satellite is still active. Guess that's okay because you need to research and verify the up and downlink frequencies anyways.

I've had the full app installed for years as it's been very useful in tracking and viewing the ISS. Accuracy can be counted on. And the sextant is a uniquely cool tool. The disappointment I've been having of late is with the Starlink satellites. Late to list new deployments and arrival timing on some have been way off.

'Ad break'... well, that's new. /..uninstalled..\ Reply to dev: this was the newest version on the play store, I had *just* updated it, and I've never seen a 'lets interrupt what you're doing to play an ad' popup prior to this. The previous 'here's an option to watch an add to unlock features' were palatable, locking the ui to feed me a full screen ad was not.

I finally looked into the short easy training. Now that i understand that it all means, i know exactly where to look for the ISSor what ever else i am interested in. Stuff i never knew about before this app. I actually pulled out my cell phone and took a few photos, hoping for at least a dot. Imagine my excitement when i saw a dot, zoomed in and actually have a photo of the iss even with the solar wings and all! I look up every time the sky is clear and some thats not so clear, nust to be sure.

Love how easy it is to customize for what objects you want to track. The location diagrams and star charts are very close to observation. I'm finding, however, that the times are off by about 5 minutes and I must consult other sources or risk missing events such as the passage of starlink trains. I have tried manually adjusting coordinates to no avail. Since predictions are consistently later than actual times observed, I'm wondering if some setting adjustment might be possible.

A worthwhile app to have on your device. However, I came to rate this app because of an annoyance. Every time I go to record the sunset from the ISS, about 2 minutes into fullscreen mode, inevitably a banner pops up at the moment that the sun is just about to set asking me to review Rate this app. Well, that is a real crappy time to ask for a Rating. And the banner doesn't time out and there's no option to turn off the asking of a rating. There's one more thing. It doesn't always show a feed from the ISS. Sometimes it cuts to Nasa Channel, but it will give messages that the sun is about to set or rise in the ISS. Users should be able to pick between watching the ISS feed or Nasa Channel. All that being said, I do enjoy the app.

This app does way more than just ISS predictions, and I have moved away from a few other applications to track/predict Amateur Radio satellite passes. One issue that it does have is that you need an Internet connection to get passes. So turn off automatic refresh and set a manual location before you leave cell coverage!

Excellent App for ISS viewing. I use this app all the time. Works perfect. Gives you an alert when the space station is going to be visible in your location. I highly recommend this app. Small amount of ads are just the right amount. This is one app I patronize the ads because it's so useful. Try it out. It may take a long time for the ISS to be visible in your location. Install it, set up notifications, and give it time.
