Choosing the right device

How do you know what kind of activity tracker to get? Shopping for an activity tracker is like shopping for a new computer or smartphone. There are several factors to consider, such as:

• Purpose. Consider what you plan to use your activity tracker for. Will you use it only for counting steps? Or do you also want to know your heart rate and how far you have walked? If you have a health condition such as diabetes or heart disease, your healthcare professional can suggest the best tracker for you.
• Accuracy. Some activity trackers are designed for consumers. Other more-specialized trackers can be used with input from healthcare professionals. Sometimes called medical-grade wearables, these specialized trackers may be available only with a prescription and have U.S. Food and Drug Administration (FDA) approval. The FDA does not test wearables sold to consumers.
• Cost. Cost rises with the number of functions a tracker offers and the number of sensors it has. There is a wide range in the cost of trackers.
• Ease of setup and user friendliness. Activity trackers with more features also may take more time to set up and take longer to learn how to use.
• Compatibility. What other devices, such as your smartphone, do you want to connect to your activity tracker? Do you have reliable access to the internet? Does your computer or phone use the same apps or websites as your tracker?

Activity trackers are most accurate when they are worn 24 hours a day, 7 days a week. It helps to think about which device may be the best fit for you and your lifestyle. Consider these factors when making your decision:

• What form of tracker works best for you? What type of tracker works best for you to wear all the time? Do you think you'd like a band, watch or ring? What might be most comfortable for you to wear while sleeping if you're considering one that can track your sleep cycles?
• Does it need to be waterproof? Does your device need to be waterproof or only water-resistant?
• Can you see the screen well? Does your device need to glow in the dark? Are you able to read the small on-screen instructions and information? Does it have tiny buttons that are hard to use?
• Battery life. Tracker batteries can last anywhere from 1 to 2 days to six months.
