Strap track devices
 

I was checking this one out and it seems it will not work with my phone. Does anyone know of a strap device that will work with all (current) major phones? If possible I would like something that is waterproof (I get messy when I bike in the muddy areas).

That's pretty cool. I'm the kinda person that would buy that just for the tech gimmicky value :lol: Do none of those watch style bracelets do what you want?

Is it just heart rate you want to track?

What phone have you got? I would imagine you need smart phone for any gadget like this to connect to which is apple or android which this works with. Looks pretty cool :)
