For anyone interested in on-the-wrist blood pressure tracking who doesn't want to spend the money on a Samsung Galaxy and hack SHMs, or wait for Apple to implement it, there are a plethora of Chinese smartwatches that already have the blood pressure monitoring and calibration capability that can be had for < $15. My experience with them is that although I wouldn't trust these to diagnose a medical condition, the trends are correct and correlate to cuff readings - they're not just random number generators. I just wish there were a way to export the data from the H Band app. Apparently, the data is stored in SQLite files.
