From what I've read RSH is used for controlling your asthma by regularly monitoring your breathing patterns. The issue that I raised is that you have a standalone device that you can only use at home or needs to be carried separately from your phone. It would have been useful if they designed it to be more portable (i.e. wrist watch)
Also the fact that they had to redesign the whole algorithm from scratch again says to me that the device wasn't very successful from the start. I'd wait until they release the results of the studies before I consider buying in.
