Calorie/excerise/HRM tracker
I would really like to keep track of my exercise a bit better so I was thinking of getting something like the Fitbit or UP3 but I really can't afford them and can't find a place that sells the UP3 in Australia. I also need it to be more plastic than metal as I have several metal allergies. (It's also a bonus if it's waterproof/resistant as I swim)
Can anyone recommend a good one, preferably under a hundred.
