Hi Jayteeto,
I applaud you for sticking to the old ways, personally, i take a flight out every so often with the gps switched off to go back to old DR ways to keep current with both but normally, i prefer marking out an updated CAA chart and keeping that between the seats or if no pax, on the RH seat if needed.
Anyway, 2 big players exist in the iPad navigation field at this time, Airbox RunwayHD and Skydeamon. It is ultimately a matter of preference what you prefer to use as Skydeamon is vector charting, that is computer generated charts that are actually very, very good and the other, scanned CAA charting with aircraft overlay.
