Mostly unusable Conceptually this is a great app. I have found some interesting and useful routes from it and there is nothing else available that does the same job. However I have now given up using it mainly because the mapping is completely unreadable on any current smart phone. The resolution is incompatible and does not scale. It is also pitifully slow to load regardless of bandwidth  exactly like the sustrans website. Geat shame.
