I have a Garmin Forerunner which I use for running (although I'm not running at the moment). I have just given up my sedentary desk job and moved to a new very hilly rural area and would like to start tracking how much walking I do in a day now so was considering a Fitbit. Phone reception can be dicey round here so I suspect an app on my phone wouldn't work (although I am happy to be corrected on this). Can anyone tell me what the best option might be please? I'm assuming I can't just wear the Garmin all day?
