Hi, John! The fitness tracker is a real treasure, even the cheapest models are quite helpful in improving our healthy lifestyle. The very fact it is always on your wrists serves as a good reminder to keep fit. Do you have any model you like after your research? How much are you going to spend on your gadget? Consider the accelerometer with 3-axis, it is able to measure directions. An altimeter is great if you love mountain trips. Counting calories is complicated, apart from the number of steps you walked, your body parameters are taken into account. Weight, age, heart rate, height etc.  Good luck, let us know about your choice!
