When you're walking, it's often handy to have an idea how far it is to the next direction so you know whether you need to pay attention or you have a few minutes to natter to your friend before worrying about navigating.
Therefore as well as the displaying the text for the current direction, the summary screen of the app provides a real-time countdown of distance to the next direction as you are walking along.
There's also a distance remaining for the whole walk to deal with any "are we nearly there yet?" although feel free to use artistic interpretation! The distance is based on a (flat) map. In reality it will be a fraction longer due to the extra (height) going up and down hills but because Cornwall is not the Himalayas then that's pretty small.
The app calculates your average walking speed over the last couple of minutes to estimate how long the rest of the walk is likely to take. We do this rather than averaging over the whole walk because your speed varies with the terrain (where possible, we aim to get the steeper bits out of the way in the first half) and also as you get a little more tired towards the end of the walk. The speed measurement ignores any periods where you have stopped or are moving very slowly so pausing to take a photo or have a picnic shouldn't mess up the estimate of the time remaining.
