Pedometer

Just seen this, I have a free app which acts as a pedometer, there are lots about mine is called Noom.

I am very pleased with mine, but it is not worn on the wrist. It is a Tanita 3 axes pedometer which can be carried in any pocket, handbag or hung round the neck. It is completely accurate, as I have counted my steps and compared! It has even been in the washing machine and dried out successfully! They are available on Ebay, in fact there is a new one with 2 days left on auction, currently only at £2. To 'buy it now' they are under £20.
I hope you find something to suit you.

I have a CSX from Amazon. Cost about £10, suits me just fine. Shows steps walked, calories burned, distance and aerobic activity.

I have a fitbit and love it.
