Knowing how far you are being heard with a distance value in the alert message would be extremely useful. Call signs are pretty much useless since they can be anywhere unless you look up each call sign independently.
Also I have noticed on the iOS app audible notification it seems to be sending a cw BX. Is this supposed to be DX?
Great app, I use it all the time to spot friends and monitor my JS8 station propagation. Again having a distance derived from grid square values would be a great addition.
