I've used SkyDemon for a couple of years now and wouldn't be without it.
Combined with a panel mounted GPS and sky demons own IFR charting it's the D's Bs, for VFR and IFR flight.
There's stacks of additional stuff like GAR filing for your first Channel hop., weather updates, notams etc.
I use it on an iPad which has given problems with overheating so given my time again I'd probably use it on an iPad mini, connected to a fag lighter socket.
Mind you I still carry VFR and IFR paper charts: I'm still in the 20th Century.
Have SD also in Android on a Nexus but it's so clunky I don't use it.
Take advantage of the SD 30 day free trial: you'll be impressed and never look back.
Their customer service is first rate: they added my airstrip to their permanent database within 36 hours of my asking.
Good luck
