The phone is essentially an Android smartphone, so it can run all sorts of apps too.
I'll be honest, I prefer "real" radio where the link is open to the variations of the ionosphere or troposphere. I can see they have their place where conventional RF radio is not possible such as in hotels or care homes, or where external antennas cannot be erected. At the depths of solar mimima, I can see them having a place too.
