Absolutely LOVE the app, especially the alert for ISS sightings! What I'm puzzled about are the other visible objects which move like satellites, but they do not appear on this app. Are military satellites hidden from tracking for obvious reasons? Potentially Space Force (insiders say we've been up there for 20+ yrs!)? Also would love to see Iridium Flares and Comets identified ahead of time. If they are available in the Pro Version, I just haven't seen any yet. Very easy to use, night view looks great and is easy on the eyes! .

This is a really useful app. I wish, however, instead of just having a filter to turn on and off all starlink satellites, it had a filter to turn on and off all starlink satellites less than a week old. After about a week or so they become much fainter and harder see. the older starlinks aren't of interest to most observers.

I love this app and have used it for several years ... since before it was an app, actually. Everything is good ~except~ now that we've moved to Arizona the Daylight Saving Time (non) observance throws all the predictions off by an hour. Can you show me how, or put in a time zone option with and without DST toggles so that the predictions will reflect local time? I imagine Hoosiers have the same problem. Thanks so much for a great app.
