Makes watching WSPR propagation easy!

I have a WSPR lite flex beacon running concurrent with a pc/receiver running wsjt-x and all I need to do is glance at this app to see the conditions. Nicely done. Love to see a paid/in-app buy version with some extra controls: a time window slider on the map, sorting by time, distance, etc on the list view. Nice work!

Love this but where’s 30M/10mhz?

I love this app. Handy, fast and just what’s needed on my phone. However, for some reason I can’t figure out, I can’t get it to show any 10mhz results when browser-based tools can. Anyone else have this issue?

Great app despite unexplained feature

This is a great little WSPR app. Glad to have found it. Love the miles (or kilometers) per watt calculation. Like others have posted it is very unclear what the colored bars indicate - no doubt know hat would make the app even better. I would also like to view the map in satellite mode. 73!
