PS, the NAIPS app, owned by OzRunways, in my humble opinion is rubbish.
It costs $10 extra for features that:
A - should be incorporated into OzRunways for your annual subscription costs.
B - are available for free via the Airservices NAIPS website (even in iPad/iPhone)
I've seen many pilots ripping their hair out over the NAIPS app's weird behaviours and inconsistencies. Of course, I'm sure that many pilots use and like it, I'm just not one of them.
