Back in those dusty bygone days of yesteryear a sports watch (aka fitness tracker) performed but two functions. The first function was that of telling the time. The second function was the chronograph – aka stopwatch. And that was pretty much your lot.


But thankfully modern training watches, which we now call fitness trackers, have undergone a monumental evolutionary transformation in technological advancement. And amazingly the average, run-of-the-mill fitness tracker possesses more computing power then was used to land a man on the moon!


Today even a cheap fitness tracker features a multitude of innovative and highly useful functions. For example, Garmin’s Forerunner 45S GPS (see inset image), which is more specifically designed for runners, not only tells the time but tracks your movement to a degree of accuracy that NASA of the 1960s could only dream of. In addition, it provides the user with precise readings regarding their vital statistics: heart rate, VO2-Max, training zones and calorie consumption. And, on top of all that, if receives text messages and calls!


And here we’ve only just scratched the surface of functions that the 5 fitness trackers featured in this article come equipped with.


However, not to get carried away, before purchasing a fitness tracker it would be wise firstly to consider what you want it for and which features/functions you are likely to use. Of course, the more functions a watch possess the more it typically costs. Also, for the Luddite or technically disinclined, more features could mean more confusion.


To help out below you will find a Buyer’s Guide which outlines essential features that a training watch should possess.



Buyer’s Guide – 3 essential features that a fitness tracker must possess


Stopwatch and lap timer

A bit of a no-brainer I know but beyond telling the time the chronograph – or stopwatch – is (in my opinion) the second most important function. A stopwatch is useful for many training eventualities, most notably timing fitness tests and tracking pacing.


Heart rate monitor

Monitoring the general fluctuations of the old ticker is beneficial beyond the bounds of physical training. Resting heart rate is a physiological biomarker that is used by the medical profession to gauge a person’s cardiovascular health. A high resting heart rate is associated with the onset of hypertension and CVD – cardiovascular disease. Thus, a watch equipped with a heart rate monitor also doubles up as a home health screening device.


In addition, heart rate monitoring is a handy tool to have if you plan to exercise within a specific training zone.


Activity/exercise tracker

The fitness tracker function, which all modern sports watches should come equipped with, records steps taken, distance travelled and (estimated) calories expended. These are handy readings to know as they provide you with an insight into your daily levels of activity while also giving your something to compete against.

The number of features that come with this watch is staggering, especially as it costs a mere £20. In addition to the array of sports and exercise functions – such as steps, distance and pace tracking – TEMINICE’s watch also provides important biometric readings.


The TEMINICE tracks and records heart rate automatically throughout the day and readings can be displayed instantaneously.


Furthermore, it monitors sleep duration and offers an insight into the overall quality of each night’s sleep. And, thanks to the new slim, super-lightweight design, you’ll not even know that it’s on your wrist.


In addition, it provides you with an accurate estimation of the number of calories consumed throughout the day. This feature is especially handy for people trying to lose weight as the data can be used to compare calories in and calories out.


The final feature of note is the sedentary alert. In conjunction with counting steps, calories and distance travelled throughout the day, the sedentary alert vibrates to bring your attention to the fact that you have been inactive for too long. Basically, this watch would be like having a little personal trainer tethered to your wrist.

Fitness Tracker FAQ


Which fitness tracker should I buy?

The fitness trackers featured in this article provide a range of innovative functions that will satisfy most needs. But, as mentioned in the introduction, prior to purchasing a product you would be wise to consider which functions you are likely to use. It is those functions that should steer your decision.


However, if you are not sure it might make sense to go for a middle-of-the-road tracker – such as the Letsfit or Tipmant – as this won’t cost the earth, but it will still feature a multitude of functions.


Are fitness trackers worth it?

For how inexpensive they are fitness trackers are certainly worth it. The wealth of data they provide can be used to enhance physical performance and to shape a healthier lifestyle. Furthermore, fitness trackers can double up as health screening devices thus enabling you to track and monitor vital biomarkers.


Are fitness trackers accurate?

Yes. The fitness trackers featured throughout this article offer an excellent degree of accuracy. And though the trackers cannot guarantee precise readings (but then no device offers perfect precision), ‘they are’ in the words of one professor of Kinesiology and Epidemiology, ‘accurate enough to be useful for most people for most purposes.’
