hows this for a mass market use?
Many are saying health related functions don't appeal to the mass market.
How about built in ECG (or EKG for our american cousins)
The watch constantly monitors my ECG, If I have a heart attack and go into VF arrest, the watch tells the iPhone to ring 999 (911) and call for an ambulance with a defib telling them your location.
Version 2 sends out a signal to all iPhones in the vicinity of the collapsed person saying someone has collapsed showing their location and shows them they location of the nearest Defib asking them to help - on arrival at scene it starts showing CPR instructions. *Might* save lives.
Version 3 - only if it detects you have collapsed - broadcasts ?bluetooth wifi etc your emergency medical details e.g. drugs. allergies signif history to a medic looking after you e.g. severe analphlaxis - give adrenaline (epinephrine)
Version 4 goes one step further - a lot of medications have a bad effect on the ECG and a lot are on meds - and so it monitors the QTc interval and perhaps looks out for R on T phenomena and warns you that you are about to have a heart attack showing you the way to the nearest ER.
There is a question of whether you would get enough info from a single lead ECG - you might need to have something on both wrists.
Most of these work best in a mass market ok not to 18 year olds but anyone over 45 or on meds might be interested.
There are other ideas for health related wearables but they are probably more related to specialist devices - Potassium monitoring, Pulse Oxygenation monitoring, 24 hr ECG, Carido memo. I wonder if the market isn't to have all the sensors in the watch but to have the watch act as the computer / central hub for devices and use the iPhone for location, environmental factors and comms.

Reading this rumor was painful. Hydration? Glucose? Non-invasive blood pressure? All of this in a watch? It would be cool and all, and who knows where this will take us further down the road, but there's one little problem... Nobody has invented an accurate way of measuring all this from your wrist. And of all the companies in the world, Apple definitely didn't come to mind.
So no thank you, Apple. I think I'll be sticking to my stethoscope and BP cuff for the time being.
Well, hydration is just measured from skin conductivity 2 electrodes is all you need.
Glucose - sorry but there are already continuous monitoring devices that you wear on your arm - they effectively pull the glucose out of your skin and measure it - i.e. needle less - not cheap at moment and quite specialised.
BP is difficult without a cuff to occlude the artery - and afiak no one is talking about the watch having an inflatable cuff, however my understanding they have hiring people expert in infrared detection of veins, well if you can find veins and arteries, you can certainly measure Oxygen Sat, pulse, and you might be able to measure some form of pressure - id need to look this up.
Ok - accuracy might be an issue, but thats just a case of money.
whether they do any of this is doubtful - again i think its more likely to act as a hub for other devices.
