RunKeeper is one of the most popular run-tracking apps for the iPhone, and today its launching a new app called Breeze to take count of how much youre walking around too. While theres no shortage of pedometer apps for the iPhone 5S, Breeze stands out by keeping its interface simple, giving you a personalized walking goal to reach every day and telling you exactly how close you should be to it during any given hour. Even so, Breeze doesnt give you quite as much to dig into as other walking trackers, such as Nike+ Move, but it also doesnt bog you down with more information than the basics, which can be a good thing when you just want to know if youre sitting around too much each day. Thats an issue other apps ignore, but Breeze isnt quite as passive.
