Simply tap “start” to …yes… start the app. Put the iPhone in your pocket and walk on (or run, if you are so inclined).
5 minutes later, a robot voice will tell you that you have been walking (running) for 5 minutes, and let you know how far you have gone, and what your speed is.
(You can tinker with the settings and have this voice share your information at many other time intervals. 5 minutes is the default, and I find that to be just about perfect.)
When you are done walking/running, you stop the app and delight in all kinds of information. Your average speed, of course, and the total time, the date, etc… But the thing that I really love is the MAP that you generate with your walk/run, courtesy of the GPS in your phone.
Here is the map that this app generated for me as I ended a quick walk this morning. Notice that I was walking on park paths so you only see my walk against a background of blank space, but if I walked in the neighborhood, you would see each and every street that was strolled upon (or run on). I loved getting the one-mile notification on the map.
Other features make this app even richer. For the average user, the free version is probably sufficient, but there are opportunities within the app to ramp up the features even further (freemium style). I will not be buying a thing. I’m happy just the way it is.
