The best tracking tool I've found short of having friends at NASA...... NOT kidding at all.
Use the feature that sends a notice of each visible pass for your location. Then have an alarm alert you when the pass is within your choice of minutes or an hour. Extremely versatile and easy to use.
Very small memory footprint even when displaying a pass. Shows the speed of the ISS any time along with it's position around the Earth. Current Crew information with backgrounds and a lot more.
This must have taken an enormous amount of time to write the programming and to keep all information current.
Like I said::: FANTASTIC!👍👍👍👍👍

I saw the ISS twice the first week I downloaded the app. I get the 5 minute alert on my Apple Watch and then head for the door with my 7 year old. It shows us where and when to look and it's pretty accurate. We thought we might miss it at first, but the ISS is really bright and easy to spot once you know when and where to look for it as it moves across the sky at 17,000 mph. I've even seen it in through the light pollution of downtown Washington DC. Great stuff!

Great App

I use this app almost daily. I really enjoy the map feature,and seeing where the ISS is in relation to the earth. The only thing that would be cooler would be for them to put in a live feature so you can look down on your area as it flies over. That would be so cool!! Oh yeah,sometimes the app isn’t exactly in sync with where you’re seeing the ISS in the sky. Sometimes it doesn’t show up at all. But that may be because NASA,or ???, may have made a last second change. Anyway,very good app.
