MileTime is for runners who want to race themselves or others. Pick your race distance: one mile, 800 meters, 5K, or another target, then whenever you’ve got a good time and place for a race, just run your fastest. No track needed.
MileTime is small and simple, with quick setup and starts, great feedback, and personal-record tracking.
MileTime tracks all your times, and your personal record (PR), by distance. During your run, it shows your current mile pace, your current estimated race pace, your time and distance, and your current location quality (mostly due to GPS, when outside).
MileTime also runs on your iPhone. You can take it running, and use the iPhone app to view and track your historical runs.
