Superb!!! 5 Star 50x10.png

by Dr fridge for version 1.4

This App is simply superb.

A HUGE APOLOGY to the developers for my previous review saying you could not view beyond mid evening. I have just found an option in the settings to view up to a week!!

I highly recommend this App to all as it is top notch, useful and accurate. Definitely a 5 star App *****


Great tracker! 5 Star 50x10.png

I've been tracking satellites since the days of pulling off TLEs from a BBS. Downloaded this program yesterday and gave it a whirl last night. It's very accurate and user friendly. Well done!

I saw the ISS fly overhead at -3.3 magnitude tonight and it was awesome! This app may not have everything but for showing 10 year olds something they expected to be lame, they're now totally stoked on the heavens and want to see more.


Geeky but great!! 5 Star 50x10.png

I love this application emoticon

I've always liked looking up at the stars on a nice clear night, but this gives an actual reason to spot something too!

Just watched the International Space Station fly over even though it was pretty cloudy - it's so bright!!


Excellent app 5 Star 50x10.png

by Capn Chaos for version 1.2

First class application. Lists all visible sats over 24hr period with very accurate countdown timer and star maps to aid viewing. Just seen STS128 & ISS. Far better than ISS Viewer.
