I'm thinking of doing Shelter's Step Forward challenge (stepforward.crisis.org.uk/) in March because I might actually manage to be more active if it's not just for me. But I need a pedometer or some other way of counting my steps. I know there are apps for this but I don't always have my phone with me. More importantly, I want one that will clip on to my clothes rather than one I have to wear like a watch. Cami anyone recommend one that's teasingly accurate but not too expensive?
