Run pacer is an iPhone application to help you with your running.

Step 1. Plan how long you want to take between waypoints on your running routes.
Step 2. Go out and run. Stick to the plan (or try to).

Run pacer does not use GPS:
Use your eyes to tell you where you are
Listen to run pacer to know where you should be.

Run pacer is ideal for use on the running track or on routes that you run often.

Features include:

Create as many routes as you want
Add as many waypoints as you like to each route
Adjust waypoints independently or together (waypoint anchor)
Record audio clips to play when you reach (or should have reached) each waypoint
Choose playlists from the music player to listen to while you run
