That in itself, is a pretty poor illustration of likely accuracy.

To get 1.42 mile in 1600 odd steps, as in the illustration, you'd need almost a 60' stride. That said, the numbers in the picture above fly in the face of this assumption. That is, if I get a higher step count, I get higher milage for the same route (so it is not, apparently using GPS). I make these assumption based on my observations walking the same route. Assuming this is the case, you need to be able to input stride length in order to calcuate acurate milage & speed, even assuming you can get the step count correct. The milage appears to be calculated by step count. This may get better as I adjust sensitivity, however, some additional comments. At the default setting it is ranging from 5% to as much as 20% over the actual step count. I am experiencing wide variations in step counts at the same settings. Now with GPS support for even better distance tracking! Continued use of GPS running in the background can dramatically decrease battery life. Keeps a history of your daily totals and timed runs.ДЄutomatic screen dimming saves battery life while continuing to count your steps, and our locking mechanism prevents accidental button pressing while in your pocket. Supports music playback, so you can listen while you exercise.ДЄdjustable sensitivity and automatic calibration allows for accuracy whether walking, jogging, or running, and multiple position settings ensure that your steps are counted whether you carry your iPhone in your pocket, belt, on your arm, or in your hand! A built-in stopwatch mode allows you to time your training sessions while it counts laps, distance, calories, and speed. Importantly, those with a higher BMI at baseline achieved relatively similar increases in their physical activity as participants with a lower BMI.Run, walk, or jog your way to better health! The Pedometer application will help you lose weight and stay healthy as it tracks your steps, distance traveled, and calories burned вЂ“ all conveniently from your iPhone or iPod touch. The PEI-FSP increased physical activity in a sedentary population.

In contrast, reductions in BMI were predicted by the initial steps per day. Reductions in waist girth and heart rate were significantly related to the increase in steps per day. On average, participants experienced significant decreases in BMI, waist girth, and resting heart rate. The amount that participants were able to increase their steps per day was not related to their baseline BMI. Steps per day increased from 7,029 +/- 3,100 (SD) at baseline to a plateau of 10,480 +/- 3,224 steps/day by 3.96 +/- 3.28 weeks of the intervention. The PEI-FSP was completed by 59% of participants. Changes in body mass index (BMI), waist girth, resting heart rate, and blood pressure were evaluated. Using subjects as their own control, physical activity (pedometer-determined steps per day) was compared before and after a 12-week intervention. Participants were recruited from five workplaces where most jobs were moderately-highly sedentary. Here, we examined the effects of a pedometer-based physical activity intervention (Prince Edward Island-First Step Program, PEI-FSP) on activity and specific health indices in 106 sedentary workers. Inactivity is a leading contributor to chronic health problems.
