This is the easiest way to spot the station.

Best ISS App


I pretty much live by this app! I love being able to add flyovers to my Calendar and the 10 minuet notifications so I don’t miss it. I’ve turned many friends and neighbors onto this app also, and we enjoy watching the flyover together. Also love the Info it gives in real time and the radar view is accurate and easy to understand. Thank you for this Great App!!

Iridium flare‘s?


Great App, the wife and I have been enjoying watching ISS and Hubble fly over. Any chance of adding iridium flares to the list?

Developer Response

The algorithms need to be rewritten to work in iOS. This takes time. On top of that, the Iridium satellites that flare will be taken out of orbit in the next year. Sorry for now, no flares. Regards, RunaR.

Finally on iOS


A few days ago I was hanging out on the beach having a campfire with a friend and we started talking about iridium flare's. When I used the "other mobile platform" I had bought this app years ago and it worked amazing however it wasn't offered on iOS. At the time I mentioned to the person "I really wish I had this app I use on my other phone". Today I went searching for it on iOS; low and behold it was just added on iOS. It's missing the Iridium's as of now but owing it on the other platform and knowing what that version has, I am confident great things will be added to this app. Keep up the great work and thanks for coming over to iOS!
