The one you'll actually wear — watch for subscriptions
Some trackers lock their best insights behind a monthly fee — factor that into the true cost. Long battery and comfort matter more than headline metrics.
The jargon, decoded
| Spec | What it actually means | Does it matter? |
|---|---|---|
| Subscription | Some hide insights behind a monthly fee. | Check first |
| Battery | Bands last a week+; full watches need daily charging. | Yes |
| Built-in GPS | Phone-free route tracking for runs/rides. | For sport |
| Heart-rate/sleep | Standard; good for trends, not medical-grade. | Trends |
| Comfort | You'll wear it overnight for sleep. | Yes |
What actually matters
- 1Watch out for subscriptions. Some trackers lock their best insights behind a monthly fee. Factor that into the true cost — a 'cheap' band can cost more over a year than a one-off rival.
- 2Battery decides daily wear. Bands often last a week-plus; full smartwatches need daily charging. Long battery means more consistent sleep and activity data.
- 3Match features to your sport. Built-in GPS matters for runners and cyclists who leave their phone behind; heart-rate and sleep are standard across the board.
- 4Comfort for 24/7 wear. If you want sleep tracking you'll wear it overnight — a light, comfortable band beats a bulky watch for that.
