A new app called Moves could be the simplest fitness app ever.
It lives in your iPhone and tracks your activity in the background, so there’s no separate device to learn how to use or remember to carry (you already have your phone on you at all times).
There’s no setup: You install it, turn it on, and that’s it.
And there’s no management, syncing, or any other “interactive” bullshit to forget to do or get bored of and stop doing altogether. You don’t even have to launch it—Moves will simply ding a little summary of your physical activity into your Notifications Center every day, where you’ll end up seeing it regardless of what you’re doing with your phone.
