Trying to beat your PB? Pacr can help - set a target time for your distance and Pacr will help you hit it.

View your progress in the app or via Apple Watch on your wrist. Periodic voice prompts are also available if desired.

Pacr uses your GPS to measure how far you've run whilst analysing your current speed. It then determines whether you're on target or not.

Pacr is a no nonsense app with a simple interface for ease of use. It's easy to change your target time and distance or to switch between miles and kilometres. Voice alerts can be toggled off or on and an interval set.

NB: Continued use of GPS running in the background can dramatically decrease battery life. Pacing accuracy is only as accurate as the GPS data available - please don't expect 'to the second' pacing, however a good GPS signal will get you close.
