What to Consider Before Purchase

There are a few considerations you need to keep in mind to work out the best tracker for you – many features may be unnecessary, and you don’t want to purchase one that does not offer a specific feature that you would benefit from. When it comes to fitness, it is important to have the right tools as it can benefit your lifestyle and overall health.


Fitness and activity trackers will be worn on your wrist, and it is clear that not everyone’s wrist is going to be the same shape and size. Some people will have small, bony wrists and small hands; others will have large beefy wrists. And many will be somewhere between these two extremes.

Fit activity tracker watch

So, before you purchase a fitness and activity tracker, you need to work out the size of the wrist that will use it, and also consider personal preference. Some people actually prefer heavier, bulkier watches and jewelry so will not mind one of the bigger trackers. Other people might be after a smaller and more subtle tracker. Think about what types of watches you prefer and go for a tracker that best resembles that.


Do not take it for granted that your new fitness and activity tracker will be waterproof or even water resistant. If you would like to use your tracker in the rain or in humid environments, then get a tracker that is at least water resistant.

Swimmers can actually really benefit from wearing a tracker in the pool as they swim, so if you plan on taking yours in actual water (ocean or pool), then look for waterproof trackers, and read the specifications to see if they mention whether they can be worn in water. Fitness and activity trackers are not always cheap so it would be a pity to break yours just because it got wet.

Waterproof activity tracker

In short, purchasing a water resistant tracker is an added bonus. Ensure you read its manual carefully to ensure the device can be used in wet and humid conditions.

Battery Life

One area where different brands and models of fitness and activity trackers will vary a lot will be in battery life. You will be surprised at how different the batteries will be on two seemingly similar trackers.

Some will need to be charged weekly (usually by connecting to a PC via USB), some monthly (or less often), and then there are a few of the best ones which have a battery life of up to a year. The cheaper trackers tend to need to be charged more often, so you need to think about whether it is worth the inconvenience of constant charging to save money. There are even some models that do not have a rechargeable battery at all – they are more like a digital in watch in that a new battery needs to be purchased after a period of time.


Some trackers come with a built-in display while some don’t. The former has an advantage in a sense that you can view both your fitness goals and time without a mobile app. The display can be colored LCD, curved OLED and many others. However, the information tracked are limited and they are way expensive as well.

Screen display

A tracker without an built-in display calls for a phone app. With this, you have to ensure that the tracker is compatible with your phone. Luckily, most bands do support leading mobile operating systems such as iOS and Android.

The key factor for choosing which variant to adopt is the amount of data you require. Sleeping and steps taken are the 2 significant areas of interest for most wearable trackers. However, many can units keep track of your swimming sessions, workouts, cycling and more. However, user input is needed depending on the activity being done.

Data Tracked

To say that a fitness and activity tracker simply ‘tracks fitness and activity’ is extremely vague. Different trackers will actually track different things, so if you are after a particular function then look at the specifications to make sure that a particular tracker tracks it. Examples of common things that are tracked include (but are not limited to):

  • Heart rate
  • Steps taken
  • Distance travelled
  • Calories burned
  • Sleep patterns

Data tracked by activity tracker

Not all trackers are going to track everything, so make sure you check depending on your needs.

Additional Features

While most trackers only track the basics like steps taken and sleep, more advanced trackers include features like increased sensors, heart rate monitors, smartphone notifications, GPS and more. In short, going for a tracker with such additional features is a good consideration depending on your needs.

Take GPS for example, it will not only help gauge the mileage covered but also help locate your position in case of anything (injury, attack etc.). In short, the latest bands are like hybrids between smart watches, fitness trackers, and running watches.
