Do fitness trackers actually help?

Activity trackers help many people move a little more: a review of 39 reviews found about 1,800 extra steps and 40 more minutes of walking a day. But long trials found little lasting health benefit, one found less weight loss with a wearable, and experiments show that counting an activity can make people enjoy it less.

What the report found

  1. Measurement has gone mass market. More than 3 million people took part in the Dubai Fitness Challenge in 2025, and Saudi Arabia's Ministry of Health runs walking leagues through its Sehhaty app.
  2. Trackers nudge people to move a little more. A review of 39 reviews, covering about 164,000 people, found that trackers added about 1,800 steps and 40 minutes of walking a day.
  3. But more data is not always better results. In a two-year weight loss trial, people given a wearable lost 3.5 kg, against 5.9 kg for those in the same programme without one.
  4. Counting can drain the fun. In a series of experiments, measuring an activity made people do more of it but enjoy it less, and do less once the measuring stopped.
  5. The famous target is a slogan. The 10,000 step goal began as a marketing name. Large studies found the benefits levelled off at around 6,000 to 8,000 steps a day for older adults, and 8,000 to 10,000 for younger ones.

  5. Questions worth watching

Plus the loop most wearables follow, signals to watch and a graded list of claims.

Who it is for

For device makers, health insurers, employers, public health teams and anyone who checks their rings or steps at the end of the day.

How we work

Frontier Reports look at behaviour the textbooks have not yet caught up with. Every claim is graded Established, Emerging or Untested. Where researchers disagree, as they do on whether wearables make people healthier, both sides are set out before we say where we stand.
