I have run several satellite tracking programs - under Palm, iPhone/touch, Mac, Linux, and Windows operating systems. I cannot get this one to correctly show orbits of one of the most popular FM amateur satellites. It senses my location. But gives very wrong results. Tried asking the developer a question: One Web site for them is not accessible; the "support" site offers nothing at all. No forum for inquiries. No email contact info for the author. I will gladly pay for good apps (Ive paid over $230 for 86 apps). But with no support and not working as each and every one of the five other programs I use for tracking satellites, I cannot support this one. I was hoping to leave this "problem report" on a support forum somewhere. This is the only place the developer, apparently, wants comments.
