Fitness tracker or smartwatch? Which wearable to buy
Both count steps and track sleep. The differences are battery life, screens, apps and price — here's how to choose.
Fitness trackers and smartwatches overlap more every year. Choosing comes down to what you want on your wrist all day.
Fitness trackers
Slim bands focused on activity and health.
- Battery: often a week or more
- Comfort: light enough to wear while sleeping
- Features: steps, heart rate, sleep, workouts, notifications
- Price: usually cheaper
Best for people who want health data without distraction.
Smartwatches
Larger screens and full app platforms.
- Battery: from a day or two up to a week or more, depending on the model
- Features: everything a tracker does plus apps, replies, maps, music and contactless payments
- Sensors: often more advanced, with built-in GPS and extra health readings
- Price: higher
Best for people who want to leave their phone in the pocket more often.
Questions to ask yourself
- Will I wear it to sleep? Then battery life and comfort matter most.
- Do I run or cycle without my phone? Look for built-in GPS.
- Do I want to reply to messages or pay from my wrist? That points to a smartwatch.
- Does it work fully with my phone?
A note on accuracy
Wearables are good at showing trends — whether your sleep or resting heart rate is improving. Treat individual readings as estimates, and talk to a doctor about any health concerns.
The bottom line
Choose a tracker for long battery life and simple health tracking; choose a smartwatch if you want a small, capable extension of your phone.
