<human>:  I want to buy a fitness tracker, but I am not sure which one has all the features I need. Can you help me?
<bot>: Yes, I can help you. To start, you could research what features you need and make sure you know what features you would like the tracker to have before you make a purchase. After that, you can begin looking at different models to compare the features and decide which one is the best fit for you.
