I was looking for a fitness tracker that leaves the user in control of their data and whose software was free and open source. There is almost nothing to choose from. There may not be anything to choose from. I've just found this band that had a very successful crowdfunding: https://www.indiegogo.com/projects/angel-the-first-open-sensor-for-health-and-fitness https://www.indiegogo.com/projects/angel-the-first-open-sens... The first batch are estimated to be released in June for pre-orders. Pre-orders are now open via their store. Their blog has some nice videos of the manufacturing process and a demo of the app: http://blog.angelsensor.com/ http://blog.angelsensor.com/
