Is there/ will there be any way of developing software for Vivomove Style/ other Vivomove watches

I'm particularly interested in using accelerometer data for health/ lifestyle applications.

I wouldn't necessarily need a UI beyond that available on a connected iOS/ Android display, so could run headless on the watch (although an event-driven sound/ haptic alert would be nice if possible, and visual UI would be great too, neither are dealbreakers for providing some user value). 

Any clues on how/ whether this might be possible?
