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.

Provides useful and accurate information and easy to use. 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!

Very interesting, fun, app, for a very senior shut-in.

I am a disabled 86-yr old whose practical “universe” is circumscribed by the walls of my rather small home. Being a life-long space buff, “orbiting” the Earth, via the ISS, gives me hours of amusement and intellectual stimulation both of which are essential for me. The narrow minds apparently reflected by some of the site’s negative reviews are to be pitied.
