@mkwadee osmand (Open Street Map for Android), offline maps installed, waterproof case.
Super handy, loads a of detail I(including public a footpaths etc), the ability to create a GPX trace and do routing amongst many other features.
I never go hiking without it now (still need a nap and compass though, their batteries last longer :grinning:)

@twistedLucidity I'm still an analogue walker.

@mkwadee phones flap around less in the wind. :grin:
I'm often in a group and I share the GPX I've created in QMapShack before the walk.
1. It's means more than one person has the route
2. I can easily tag points of interest (read: pubs)
3. If the worst happens, I can give long/lat to rescue
4. It stops all the arguements on which way is correct!
Still need to be able to read a map and know where one's going, lest one suffers unexpected cliff syndrome.
