Apple is touting the Apple Watch using three main arguments. The first is that it keeps time, and is accurate to within 50 milliseconds. (I'm so relieved by the fact that a watch in 2015 can be accurate, aren't you?) The second is the "fun, spontaneous ways" you can communicate with "your favorite people." And the third is probably the best selling point, given the way people have used wearables up until now: it offers "a smarter way to look at fitness."
I have to agree with that. The tricircular interface on the Apple Watch's Activity app, which shows how much you move, exercise, and stand, is a brilliant design.
However, much of the Apple Watch's data will be piped through to the Health app on your iPhone, and the interface of that app is sorely in need of a redesign, even if we do get a separate companion Activity app for iPhone too.
There is a huge disconnect between the simple, intuitive interface of the Apple Watch and the dry, archaic look of the Health app. With nothing but straight graphs lacking easy-to-spot dividers, the Health app displays data in ways that will put off even the most earnest of exercisers.
In addition, while it's not as obvious in this screenshot, it's very difficult to read the above numbers on an iPhone because the thin, white font doesn't offer much contrast. Depending on which type of metric you select, the Health app chooses colors for the dashboard cards. You can't opt for a more readable color, and the fonts are all white, against a variety of light-colored backgrounds.
Other apps make reading data much easier. Using Fitbit's app, I can see at a glance, in large, readable numbers, what my activity level is, with step counts, distance, calories burned and more. And if I tap on the Step count, I see a weekly view that is still more informative than Apple's.
The Fitbit app also lets you set goals, something that is so far absent from the Health app. You can set daily goals, and the colors in the dashboard reflect whether or not you've met them. (The Apple Watch site mentions daily goals; presumably these will be rolled into the Health app in an update when the Apple Watch ships.)
The Health app also has an odd way of displaying raw data. For some metrics, this might work — think blood glucose levels, blood pressure, and weight for example. But for steps, it's simply incongruous. Look below at the way you view step data for a given day:
It would make sense for this to be grouped by, say, 15-minute intervals. I can't imagine that, for most people, seeing the number of steps per minute would be very useful. Compare the above with the way the Withings iOS app shows daily step counts:
