I love this app. Spot on for ISS crossings , ample info for nightly events.
This is a great app for amateur astronomers.
User interface is an 8.5! Was outlast night, was able to ID at least 4 satellites & 2 stars & I'm using the free version!
I use this app quite frequently. Only thing that irks me is that I can't download fresh data when I'm hooked up to my VPN. So it sees me outside the US and won't grab the fresh data. Is it worth a full star deduction? No, not really. But I can't do half stars on the rating system.
It was a really nice experience with this app
The HELP option in the menu is unhelpful.
This is a fantastic, informative, smooth running app that I use very often. ****FYI: There is one issue that just started today, upon opening the app multiple time satellite data data didn't automatically update like it usually does.****
When I use dark theme on my phone, that white circle locator goes black against night sky so its hard to spot.
Simples de usar e leve para celulares com pouco processamento.
I am enjoying the app however when I tried to get help I am directed to Reddit and have been unsuccessful acquiring the information desired to utilize some of the functions. For instance how to choose or select a pass.
