Filters are great to get a list of just what an amateur radio operator would want. Or for an ISS observer only interested in high striking passes. Or filter on the low to zero elevation passes if you like.
Another source, or past experience, is needed to know which AMSATs are actually active. Lots of them are still on orbit but long since inactive. Once an Active list is made, a manageable list is produced.
What is really nice is just the information an Amateur needs for field work. Details on the pass, ground track map, and the Modes, Uplink and Downlink frequencies come up with one click on the satellite of interest. More than that is far too much data unless already stationed at a ground base with computer tracking decoders...etc.
Virtual reality will be interesting to test. I can see it being useful as a pointer. How to place the phone in an already equipment-busy setup is yet to be seen. As far as the screen closing, that is more of a Phone screen saver issue than ISSDetector . The phone will blank the screen on every app I’ve used unless you tap it every 30 seconds .
