Apple has reportedly bought Tueo Health, a startup that was developing asthma-tracking technology for use with sleeping kids.
Tueo was specifically developing a mobile app compatible with commercial breathing sensors. In case of sudden problems, the app would push out an alert.
Apple's aims with the acquisition are uncertain, but CEO Tim Cook recently admitted that it buys a new startup "on average every two to three weeks," and primarily for "talent and intellectual property." It could be therefore that there are no asthma-related hardware or HealthKit plans.
WWDC 2019 schedules recently revealed plans for hearing health in iOS 13, however, and the OS as a whole is expected to include new health features when it arrives this fall. Cook has previously argued that healthcare will be "Apple's greatest contribution to mankind."
Publicly, Apple is known to have bought two other health firms so far. It bought records specialist Gliimpse in 2016, ultimately using that to launch its own records-sharing system. It bought sleep-tracking firm Beddit in 2017, but hasn't taken advantage of that beyond a poorly-received redesign of the Beddit Sleep Monitor.
