Clew is a very simple app that doesn't have much in the way of an interface. It is very straight forward to use. Would love to see the ability to save routes that I've created. Right now, it only gives you the option to create a route to Point B and then gives you the directions back to Point A. Essentially this is a disposable one time only route creation. This has potential and something I can use in different situations.
This was taken from the developer's site and found that it may answer some of your questions:
"Clew works best in well-lit areas with distinct visual features and few moving objects like crowds and cars. Although Clew can be used outdoors, it is
not as accurate in open areas and intense sunlight. Clew works optimally indoors over relatively short distances."
