Pretty useful. Stopped working this week.

Found this very useful for the few ham says that I have used. I love watching the ISS.
But this week I noticed when it wants the download tle data it crashes. Downloads the first 11-12 parts and then crashes the app. It just closes.
I use iPhone 5 with the latest iOS updates. The app has worked great till now. I have used this app since I had a iPhone 3G then used an iPhone 4g.
