I have just tried Runway HD as it allows a free trial without subscription. I didn't find it as good as SkyDemon for flight planning.

Aware are now offering an airspace warning app which you only have to pay one off for the charts. It looks like a good app with the ability to view 1:500k and 1:250k charts. I think I'll take the plunge on this one and use this on my knee when flying and keep using SkyDemon Light for flight planning.

Has anyone tried the new aware app?
