Runtime is a new run/walk tracker for iPhone that was completely designed with iOS 7 in mind. You can plot and track your runs so you can perform them again later if you'd like. Runtime also supports the iPhone 5s' M7 motion co-processor to allow you to use Runtime as a general purpose pedometer too.
Upon launching Runtime, there are a few demo runs available that give you an overall idea of how to view, start, and stop a run or a walk. Any time you spend resting or sitting will be marked in yellow so you can see how you're progressing over time on a certain trail or route.
Runtime supports backup and sync through Dropbox as well so if you ever need to clear your iPhone or transfer data to another device, you can simply download Runtime and have all your data come down just as you left it. You can also share routes with other Runtime users via email or AirDrop if you'd like.
If you happen to try out Runtime on iPhone, let us know what you think via the comments. Since so few apps really take advantage of the motion co-processor yet, I'll be curious to see what the impacts truly are on battery life once we've all got enough of the running in the coming months.
