I am novice user of this app so forgive me if i did not understand all the options yet. Here are my observations:
Frequencies list for satellites seems to be available only on satellite details screen which is accessible only from Passes screen.
From user point of view, it would be useful to access satellite and especially frequencies info regardless Passes. Thing is Passes list shows each pass so it my be lengthy list requiring scrolling to find right satellite. And it is a bit counterintuitive.
Satellite detailed info could be accessible from map to, for example, by clicking on satellite icon shown on map.
The other issue is that on satellite details screen, font size for frequencies list is too big. I do not know if it is some global setting on my phone or else, but it is not nearly as nice as in screenshots on your site. I have fairly big screen but only one frequency mode can be seen. Option to set font size for this may help.
Satellite pass graphical compass is on the other hand unnecessarily big. It can serve purpose if twice, maybe three times smaller, leaving space for textual info which has to be read.
There is option to filter satellites by radio mode, which is excellent stuff. TI would be helpful that user can set mods he can actually use and use that to filter out data about satellite - like radio frequency list. It makes sense to hide some radio frequency info if user has no means to use it. It would increase readability of useful stuff on the list.
