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!

Excellent Application

This app is very well designed and very accurate, the menu looks professionally designed. The weather upgrade is only a dollar, which is not very expensive. The information about the crew members of the ISS is very detailed and interesting. I would highly recommend this app for anyone who wants to see the ISS, and learn more about it currently.
