App is great for tracking the International Space Station

I have other general apps or software programs about space that will show me where the ISS is, but this is a fantastic app for keeping tabs on when you can view the ISS in your skies. I had alerts set that popped up in my calendar with the perfect amount of lead time - without any real thinking or planning on my part. This app makes it easy. Thank you.

I have used this many times to view the ISS. App functions as it should and makes keeping up to date on location so easy. I like the extra information on each astronaut and adds to the enjoyment of seeing and knowledge of the specialities of the astronauts. Thanks again for providing this.

So glad you like the app and that it's helping you in viewing the ISS. Thank you for your great review and feedback!
Developer very responsive to app suggestions

I suggested adding an config option so that the ISS wouldn’t pulse when viewing. He responded that it would be implemented and within a few days a new version was available with that option. Much easier to watch now.
Don’t go by negative reviews

This is a well made and useful app, a few quirks with the UI, but if you want to track the ISS, see what it is seeing, and plan future viewings.There are issues with map positioning especially if I drag my finger around to move the map underneath the station. I recommend this is disabled and always keep the ISS centered in the display, zoom in/out is ok. Also, plot the ISS path to show on map where it is/will be tracking over.

Great feedback. Thanks!!!
