Activity trackers can help to improve your fitness (update)

Activity trackers appeared on the market only recently, but have achieved substantial popularity. Most popular is the Fitbit range1.

Obviously, by itself, an activity tracker will not improve your fitness. You do have to actually get out there & walk, run, play sports or whatever, but, a fitness tracker can:

● accurately2 count all of your steps in a day without any monitoring or other intervention on your part
● for at least some users, act as an incentive3,4

An alternative to a dedicated device, is the Misfit app for the Pebble smartwatch. Free on the Pebble app store.

A user did a side-by-side comparison with a Fitbit Flex, which is known to be accurate:2

In both instances, the Misfit app on the Pebble counted high:

6 hour test
Fitbit Flex - 7,249 steps
Misfit app for Pebble - 7,485 steps
(7,485 - 7249) / 7249 * 100 = 3.26% higher

9 hour test
Fitbit Flex - 10,222 steps
Misfit app for Pebble - 10,536 steps
(10,536 - 10,222) / 10,222 * 100 = 3.07% higher

Keeping in mind that this is based on only one sample of each device, the inaccuracy is not significant.

With the Pebble now at $US99, & the Misfit app free, this combination is a viable alternative to a dedicated device. For anyone who already has a Pebble watch, it’s a no-brainer.
