Prior to the official announcement of the Apple Watch, there were multiple rumors that the device would be packed with health-related sensors. When it finally launched, however, it got just a heart-rate monitor – albeit a sophisticated one. A teardown revealed that there’s also a pulse oximeter in there, to measure oxygen saturation in your blood, but Apple hasn’t yet activated that functionality.

The apparent turnabout on sensors was explained by Tim Cook, who last year told the Telegraph that Apple wanted to avoid the need for FDA approval as a regulated health product as that would slow innovation. Any additional sensors, he strongly hinted, would be external.

If you don’t want to wait that long, however, health-tech company Azoi has launched the Kito+, a credit-card sized unit that pairs with an iPhone app to measure heart-rate, ECG, blood oxygen, respiration rate and skin temperature. Costing £99 ($145), you can either use it as a standalone unit, or slot it into the supplied iPhone case for the iPhone 6/6s/Plus …

Biometric specialist Valencell – whose technology is licensed by iRiver, LG, Sony and others – has filed a lawsuit accusing Apple of using underhand tactics to gain access to its patented technology for use in the Apple Watch.

The company claims that Apple violated three of its patents for improving the accuracy and reliability of heart-rate data when using the photoplethysmography (PPG) approach used in the Apple Watch. But the lawsuit alleges more than just patent infringement, reports AI: it also claims that Apple used deceptive techniques to get access to the technology …

Apple Watch running the original 1.0 software rather reliably recorded a user’s heart rate every ten minutes. With Watch OS 1.0.1, users noticed that heart rate records were no longer being kept as frequently. This was initially thought to be a bug but Apple has now clarified that this is intended behaviour on its website.

The updated website says that ‘Apple Watch attempts to measure your heart rate every ten minutes, but won’t record it when you are in motion or your arm is moving’. The original version of this feature did not care about arm movement.

Apple’s update to Watch OS 1.0.1 was intended to improve the performance of several fitness-related functions, but also appears to have introduced a bug. Instead of the Apple Watch recording your heart rate every ten minutes, many users – including myself – are seeing large gaps in the data.

My readings for yesterday afternoon and evening, shown above, contain four gaps of more than an hour. Two of these gaps span times when I was cycling, when the data would have been most relevant. Users in an Apple Support Communities thread (via EverythingCafe) are reporting the same thing …  expand full story

Apple has confirmed reports of problems using the Apple Watch on tattooed wrists. The company has quietly updated a support page on the heart-rate functionality.

Permanent or temporary changes to your skin, such as some tattoos, can also impact heart rate sensor performance. The ink, pattern, and saturation of some tattoos can block light from the sensor, making it difficult to get reliable readings.

Apple Watch owners on Reddit and Twitter have been posting conflicting reports and video, some showing that the heart-rate functionality works fine with their tattoos, others showing either no reading at all or erratic readings …  expand full story
