Fitbook.es is a online application that records all your body measurements (weight, body fat, waist, arms, chest, legs...) and builds graphs of them for online publishing. The site can be integrated with Facebook to share data amongst friends. The fitbook API allows developers to integrate the service into their apps and sites. The API can be used to show data visualizations of weight and body fat loss. It uses REST protocol and responses are in a graphical format. The site and documentation are in Spanish.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
