I just noticed that you integrate with the Jawbone UP service. I think you should consider integrating with the SAGA lifelogging service too (getsaga.com). You'd be joining, Up, Mapmyfitness, foursquare, fitbit and many others. It seems that logs of completed trips would be a perfect addition to this service, and the users would be a segment that would highly interested in finding another way to log their world (i.e. could be a target market).
