The iPhone can do many things, and seemingly it can even be used as a running training aid. There are dozens (if not hundreds) of fitness apps for Apple’s smartphone, but among the most interesting is one call iTreadmill. OK, while the app doesn’t somehow actually let you run on the touchscreen – but it would be cool if you could somehow do so – it does however act as a digital chronometer, 
keeping track of the distance you’re doing.
This is whether you’re actually doing miles outside, walking around your house or apartment, or just running in place. Put it in your pocket and go, as this app detects the slightest movement and thus tracks the distance you’ve covered. Should you stop to tie your shoe or wait for a light, or just answer the phone, the chronometer will automatically stop. Based on what it reads it can provide you details of your average speed, distance, pace, step count, strike rate and even calories burned. It doesn’t track heart rate however, so you’ll have to stick with a traditional heart rate monitor if that’s important. However, this app includes some interesting features, including a pace setting that provides a flashing light and ticking sound to get you moving. Now if only this app could actually make running in place at a hotel a little more exciting.
