What to look for
- Decide whether you need built-in GPS; without it, runs only map when you carry your phone.
- Check subscription costs, since some brands lock their best insights behind a monthly fee.
- Comfort matters for sleep tracking, so a slim band or ring beats a chunky watch overnight.
- Look for at least five days of battery so charging does not become a chore.
How much to spend
Typical prices run from £59 to £459. Budget models cover the basics; spending more usually buys accurate tracking with built-in GPS in a slim band. Only pay for features you will use.
Who should skip what
- Skip the Fitbit Charge 6 if you want a big screen, apps or deeper training data than Fitbit offers
- Skip the Amazfit Bip 6 if you want polished software or contactless payments that work everywhere
- Skip the Oura Ring 4 if you do not want a monthly fee; most insights need an Oura membership
- Skip the Garmin vívosmart 5 if you want built-in GPS for runs; the vívosmart uses your phone’s GPS
Buying tips
Fitness trackers are popular New Year and Prime Day deals. Factor in any membership fee before you buy, check that the band size fits your wrist, and keep the receipt in case you need a different size.

Frequently asked questions
Are fitness trackers accurate?
For steps, heart rate and sleep trends, good trackers are accurate enough to be useful. Treat calorie burn as an estimate rather than an exact figure.
Do I need Fitbit Premium?
No. The Charge 6 tracks steps, heart rate, sleep and workouts without it. Premium adds deeper insights and guided programmes for about £10 a month.
Fitness tracker or smartwatch?
Pick a tracker if you want a slim, light band and long battery. Pick a smartwatch if you want apps, a bigger screen and calls on your wrist.
