It’s ADSB Flight Tracker Lite , a very customizable app
It can directly connect to a dongle (with RTLSDR android driver), to a Virtual Radar Server or to dump1090/tar1090 with cutomizable url, but also to adsbexchange.com through an internet connection, you can simply switch between servers with one click.
You can also import your own boundaries (TMA, airspaces, airways, FIR…) with .txt files wrote with a pretty simple language
Free version of that app works only for 5 minutes, there is no way to do one-off app purchase, one only to subscribe for a monthly fee.
No way to cache the map; the loaded map somewhat abysmal and cannot be compated to the one of Avare ADSB.
I’m too quite interested in the parent topic of having offline instance of tar1090 with preloaded local copy of OSM or any other map tiles.
Unfortunately I know nothing of how that can be done, any suggestions are very welcome!
I tried quite a few things, it’s really annoing.
I suppose some very very coarse map (country level) could be done.
Anyhow it’s not fun in the least.
Which app is “that app”?
Thanks @LawrenceHill
Id love to run my piaware with no internet in the garage. Is there a way store the openstreetmap locally? I would just need my state.
Maybe tar1090 as alternative viewer is the thing for you.
There are some discussions about offline maps:
@wiedehopf is the maintainer of tar1090, he might give answers to it if it has ever implemented.
