Today, Apple revealed the Apple Watch, the much-hyped smartwatch that the company has been building up since it was first mentioned last September. It is a highly customizable wearable (even with a Mickey Mouse face) and several impressive features, including the ability to take calls on your wrist (!), plus Apple Pay and Siri, and many third-party apps like Shazam. It is a machine of excellent convenience (not unlike Android Wear for Google addicts) and great design.
Apple CEO Tim Cook also called it a "comprehensive health and fitness companion." The watch has lots of fitness features, primarily in the two fitness apps: Workout, for data tracking during a run or on a cardio machine like an elliptical, and Activity, for everyday fitness stats like steps taken or calories burned. Those look pretty slick, but we have a few dream features for the Apple Watch that we would like to see someday. Many of these are flat-out unreasonable requests—and it should be noted that Apple has opened it API with WatchKit SDK for developers to make future cool fitness apps—but we thought they should be mentioned. The Apple Watch starts at $349 and will begin shipping soon.
Continuous heart rate monitoring
One thing we'll likely be missing for a while: continuous heart rate monitoring, or long-term monitoring, that can help you find heart rate variability and better determine overall fitness, like the features built into the Fitbit Surge, Epson Pulsense and other Mio trackers.
Likely due to how short the battery life is, you can't exactly wear the Apple Watch at night, so there's a low possiblity of sleep tracking like the Withings Activité Pop.
VO2 Max Estimate
VO2 Max is the maximum rate of your oxygen consumption as measured during exercise, and a great way to tell if you're in shape. Few wearables do it, but some have estimates like Garmin's fenix 3 and Forerunner watches.
Barometer and altimeter
Athletes know that they need to know the air pressure and elevation that they can get with the Garmin fenix 3. Well, they don't, unless they're super athletes.
Microsoft began experimenting with ways to track sets and reps without inputting them manually with the Microsoft Band. Hasn't caught on so far, but at least they're trying. No weight trackers from the Apple Watch.
