The Move goal is adjustable — I can lower it at any time — but there’s no way to program the Watch to consistently honor my rest days. I just have to manually lower the goal for that day, and then raise it for the next one. Unfortunately, this requires too much of my attention. I have actual things to do that are more important than manually telling my fitness app to let me rest, so mostly I forget to do it until it’s too late. Even when I remember, I wind up with a different problem: I forget to reset the Watch to a higher Move goal the next day. I spent one week being psyched that I hit my goal only to discover that I had only hit the lowered goal.
It’s two years later, and several versions of WatchOS have come and gone, with another is forthcoming. And yet Apple hasn’t fixed this very common and very basic problem with their wearable line of products.
Apple has repeatedly stated that it recognizes that the Apple Watch is a super popular device for fitness tracking, and I can attest that it’s about the best wearable that’s currently on the market. But when the world’s richest company can’t even get the basics of their product right it raises questions about what it’s really focusing on, and why; pushing people to exercise each day, and forego rest days, is harmful to health and fitness alike. Sadly, it doesn’t look like the current Watch betas fix this problem, though maybe Apple will surprise people with some extra promise when they reveal their new devices in the coming days.
