I've had a B1 for 1.5yrs. They've promised a public API since before that time, but it still doesn't exist. In fact, I have a hard time thinking of any features they've added this entire time (in fact it's terrible as a watch since you can't set the time/time zone except via the web and after a full data sync, making it often useless if you travel much). I finally got the Amiigo a couple months ago - I didn't see SpO2 stats detailed. It was actually pretty underwhelming - the Amiigo doesn't have the promised API/SDK either. The MS Band's sensor suite is better (GSR, skin temp), it's just too bad it's not waterproof.
