Apple’s fault this can’t be a downloadable watch app. WatchOS doesn’t enable onboard data processing to trigger events (increased heart rate for haptic feedback). So the data has to be sent to HealthKit on the phone. But developers can’t access that data when the phone is locked, like while the user is sleeping. So now the developer has to pre-load a watch and phone and the product becomes much more expensive to include both. Kudos to the company for making it work, just shouldn’t be this hard to deploy software.
