Pedometer or fitness monitors iPad phones etc

[poo at Paul's]

Anyone have any of theSe numerous devices..

I have an iPad, not 3 g, and an old original iPhone that I use as an iPod only. Is ere anything like a pedometer, or some hr monitor that I can wear, and download the activity data over. Day or week into one of the devices? Bluetooth hook up ?

If it is iPad compatible, is there one that sites the data on board, so I don't need to carry the iPad whilst jogging!

I want to keep an eye on how much I do during a day, I know a cheap ped will work but fancy something tetchy that works to keep me interested.

Someone said Nike did a thing that went on your trainers but I want to carry something on a belt or pocket ideally, so I can wear it at work.

Any ideas?
