Exercise tracker

Hi all sorry if this has been asked so many times before but want to start tracking my exercise better what is the best device and most accurate to do this. I'm interested more in calorie burn and steps. Tia. Also how accurate do you find MFP to be when you log an exercise. I always use what my treadmill says but MFP gives me another result and obviously it's knows it my weight and height etc. Has anyone found it to be accurate when they've brought a fitness tracker device thanks all ☺ x
