From what I understand, the software is not a legal as the sole means of navigation, basically because the program / hardware has never been qualified for aviation use
You ought to ask the source of that statement for a reference, because there isn't any
In VFR or IFR private-flight (non AOC) there is no concept of sole nav, primary nav, or any of the many similar concepts one often reads about.
Towards the end of last year I had landed at an airfield in Germany when the Bezirksregierung came in to check on the Pilots who were flying - licences, medicals and the like. What they were
also asking to see was the flight planning which
included navigational material. One guy showed his iPhone with ANP, complete with Course preplanned; he was then informed that this was NOT suitable for use as the primary means of navigation......
Now, this might be a case of semantics - primary navigation in this case meaning a valid chart - but on it's own, Air Navigation was not considered by the inspectors of the BR suitable for flight
without a second means of navigation - ie, an actual chart.
