GoSatWatch Satellite Tracking 4+

I purchased GoSatWatch only because the app I was used to using on Palm and Windows Mobile was, at that time, not available on this platform. As one of my earliest purchases it was a revelation of how nicely an iPhone/Touch app could be done. The design aspects and the functionality are almost impeccable. You could easily be outside looking at a satellite within 10 minutes of buying GoSatWatch. It's so simple to use and the setup required is minimal. The only reason I didn't give 5 stars is because it does not let me easily see passes over a longer period, say for the next week or month. Not to say you cannot quickly step through the coming week, but when a satellite only occasionally has visible passes over your location, it would be much nicer to simply see the next month of passes. There's also a slight quirk in the way passes are displayed. For example, after pressing "Tonight" you will see today's date and a line with today's sunset time. There will also be a line for tomorrow's sunrise. Between those lines are passes. You need to be aware that if it says "AM" the pass is tomorrow. I guess this makes sense, but when I first used GoSatWatch early one morning and saw today's date at the top with a predicted pass of "5:30 AM", I thought it meant a pass was about to happen. I still feel a little bit uncomfortable with that minor thing. But overall, GoSatWatch does a great job and it's a bargain.

After wasting my money on a couple of other Sat/ISS apps I am so glad I found this... and finding it on App store was the difficult bit! (maybe not the best name to use?!)
I just LOVE this app. The graphics and usability are slick and professional, and unlike other Sat/ISS apps I have used you are not limited and can custom your sky view to have as many or as few Sats/objects as you like. I especially like the time control to wind the Sky and Map views through the future - really smooth responsive and informative, and it is really easy to calcullate future passes to your criteria (Visibility/Min Elevation/Magnitude). I have so enjoyed this app that I bought the GoSkyWatch Planetaruim which is equally impressive.
