What knot?

Knots can be tricky to learn and require practice. I was quite chuffed when I learnt how to tie the truckies hitch many years ago. I find it useful when using extra guy lines to tighten the fly on my tent.
What knots do you regularly use when bushwalking? What are your favourites and why? What do you use for different purposes? What do you use when scrambling and pack-hauling?
There is an iPhone App called 'WhatKnot' that I find is quite useful. The names of some knots are confusing though ( the truckies hitch in this app is not the one I'm familiar with ).
