best fitness tracking device

I have a Fitbit One and a Polar FT60. The fitbit is great about making me aware of the effects of my general daily activity (or lack thereof). The Polar helps me determine the calories burned in my workouts (so I don't eat too many back), and helps me keep my workouts at the intensity level needed to make progress in my fitness goals.

I'll second this. I have a fitbit Ultra (circa 2012) and and Polar T4. I have worn my fitbit continuously since July 2012 and it keeps me very aware of my general movement during the day. I nearly always get my 10,000 steps in and set goals to get more than that. The HRM allows me to calculate calorie burns more accurately for formal exercise activities.

I also find data very motivating. I have even set better sleep goals for myself since I track my sleep with my fitbit.

now alot of reviews say they fall off, have you had any problem with yours?

YES. I loved it for two weeks. It would pop off from time to time and I felt it come off. But the last time it popped off I never felt it drop wherever I was at the time. It is gone and I'm out $129.00. Not going to replace it even though it worked just fine.

I like my fitbit one alot. Have not had any problems with it coming off at all, but it is not the "watch type" model it is a clip on. It seems to track calories burned pretty well too, I track food on MFP and fitbit syncs with it and will give you your overall calorie deficit for the week and it has been pretty close to what I actually lose since I have had it. I also use a PolarFT4 for cycling and weight lifting to give me a good idea of burns since fitbit cant really measure that stuff well. Rukeeper is a good app that is free for smartphones. It uses GPS to log you runs and can give you more information about your route and speed that the fitibit will not give you if you are training or anything. That also syncs w/ MFP. Those are the ones I use but there are lots of options and alot of it depends on what kinds of exercise you like to do.

I've been recommended the jawbone up, getting it tomorrow will let you know.

so i got my fitness watch today, i bought the polar ft7 from target and I'm super disappointed by it. perhaps my expectations are unreal for what i want. it has the heart rate sensor but its a chest strap... i wanted it built in to the watch (maybe not possible) i want it to count my steps for the day, and it dose do that but the all in one kinda bums me out. ohh and i want it to sync to my iphone via app or computer etc. not just lose the data. any one have a better idea of what i'm looking for?
i did review other topics though i couldnt find anything with everything included in an all in one product like i'm looking for.

You need the chest strap - although there are HRMs on the market that don't require the chest strap, they're notoriously inaccurate, to the point of being useless.

What you're looking for is a combination activity tracker / HRM, that uploads to an online database. Check out the Polar Loop, and the Garmin Vivofit (although I don't know if the Vivofit is out yet).
