Smartwatch or fitness band: which should you buy?

Both track steps, heart rate and sleep. The difference is everything around that.

Pick a fitness band if

• You mainly want steps, sleep and workouts
• You want a battery that lasts one to two weeks
• You want to spend less

Pick a smartwatch if

• You want to reply to messages and take calls from your wrist
• You want GPS for runs without carrying a phone
• You do not mind charging every day or two

Health numbers from both are estimates, not medical readings. Use trends over weeks, not a single reading, and talk to a doctor about anything that worries you.
