Heart Rate Monitor watches

Ok, so I am in the market for a heart rate monitor that tracks heart rate as well as calories burned during workouts. I know many of you use the Fitbit, but I kinda skipped it because it isn't compatible with my smart phone...and I will be honest, if I need to sit at the computer every day to log, I wont do it. I have looked at the Polar ones..but apparently some have issues with being bumped during a workout and then you lose your data..NOT COOL.

So if you use one, give me your likes and dislikes! I would greatly appreciate it. Also if you have upgraded to something better and wanna sell your old one, let me know!

have you looked into the UP by jawbone.it looks pretty good
