I've downloaded the fitbit app and I'm going to buy one tomorrow yay! (Hopefully anyway!) the flex is currently $85 at harvey norman. Hubby is pretty keen to get a charge (because of the watch feature mostly) so that'll help the both of us even though he is pretty slim his diet is atrocious compared to mine even though I'm overweight. He lives on a diet of energy drinks and maccas so I'm hoping this will motivate him to eat better!
I'm hoping to join the challenge tomorrow too!
I'm also on my fitness pal with the same username
