Side note: Reporter remains hands-down the best pedometer app I've seen so far.
(Most of the iPhone 5S pedometer apps out there are surprisingly stupid. They do very little other than tell you how many steps you've taken. They fill the screen with ballooney information-poor Pravda-style "infographs" to distract you from the fact that they don't really have much to tell you. They don't update in the background so if you unless you remember to explicitly open the app every week you'll lose data about your steps. And they don't offer a way to export the data to a format you can use elsewhere.)
