5 stars: 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!
5 stars: Absolutely loved the app. Was able to track the ISS passing over Miami for the first time in my life. It was visible right from my window and was truly a life-changing experience... wow. I showed my parents as well and they had never seen anything like it before.
5 stars: very useful and well made app. i use it to track amateur radio satellites in addition to the ISS. It even computed the current frequency shift.
5 stars: The app works excellent for what is meant to do. I receive notifications 5 minutes before the ISS comes visible for me and the app shows me exactly where in the sky I have to look.
5 stars: it is always extremely exciting to navigate to where the sighting will take place and everyone is standing close looking into the sky hoping they will spot it first.
5 stars: excellent! nothing to say! too bad the iridiums are going out of service
5 stars: Awesome for tracking amature radio satellites. includes many filters for other satellites and other earth orbiting objects.
5 stars: Easy to use, very well designed software. Works flawlessly for me.
