Ratings and reviews

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! .

My first sighting of the ISS was thanks to the Heavens Above website in 2006 or so, and have been using them ever since. Having all the same information about passes and what is visible in app form is great. The app works very well, and has a night mode. I don't usually pay for full versions of apps, but I'm happy to support the Heavens Above team.

I just wanted to make comment that paying for the pro version to avoid the ads was unfair. I expected no ads which is what I got but I also expected more features but got none. Apart from having no ads it is no different to the original. I got blocked by reddit for signing out and signing in again. Apart from these hiccups I only ever use this ap. I would advise other users to save your money and stick with the ads version.
