All you need to know before buying a great smartwatch

Picture of a smartwatch

Smartwatches are becoming increasingly popular with consumers. Capable of offering a range of helpful functions, these mobile devices are going to be a mainstay in the future, giving even more reason to buy one now!

Finding the best smartwatch for your needs can be difficult however, as there is an overwhelming choice of products available. Plus, given how new the technology is, not everyone is aware of what to look for in a smartwatch. Check out this buying guide for all the info you need to buy a great smartwatch

What are smartwatches?

A smartwatch is a mobile device designed to be worn around the wrist. While it closely resembles a wristwatch, it has the features and functions akin to a smartphone, just on a more compact scale. They perform a wide range of tasks, including calculations, time telling, translation, fitness tracking, and even playing games.

Essentially, the best smartwatches are wearable computer devices using mobile operating systems and applications.

Why should you buy a good smartwatch?

While relatively new, smartwatches have a long future ahead of them, providing a range of benefits to the modern person. For example, they connect directly to a smartphone to provide notifications directly to the watch, which saves you time checking your phone (and getting distracted as you do so!). As they work similarly to a smartphone, there are a range of apps that can make your life much easier and possibly healthier. For instance, fitness tracking is a big selling point for smartwatches, allowing to check your fitness levels and performances. 

These are just a few examples of the many benefits on offer, most of which will improve over time.

How to choose the right smartwatch?

Choosing the best smartwatch is much easier if you know what to look for in a device. Here are some things to consider:

  • Compatibility: You want a smartwatch that is compatible with an appropriate smartphone. For instance, Apple Watches only work with iPhones, and while Samsung smartwatches connect to iPhones and Android smartphones, although these have devices have more features available when used with Samsung mobile phones. Be sure to think about your current smartphone before buying a smartwatch, as it ensures you get the most out of each device.
  • Interface: The best smartwatches are often viewed as those with LED touchscreen interfaces, but this isn’t necessarily the case. While certainly a cool interface, it’s sometimes difficult to control touchscreen smartwatches, so you may want to consider devices that use buttons, or a combo of buttons and a touchscreen. However, a smartwatch with buttons and a basic interface is going to be much cheaper, while their functions may remain just as useful.
  • Features: There is a huge range of features available on every smartwatch, so it’s important to think about what you want them to include. They all function as a watch first and foremost, while the best smartwatches offer notifications from mobile phones, but beyond this there is a limitless selection. For example, many are designed with fitness in mind, so if you are buying a smartwatch to help get in shape and stay healthy, then be sure to look for devices with features that are fitness focused, including things like GPS tracking and heart-rate monitors.
What is the best kind of smartwatch in the UK?

  • GPS Smartwatches: Perfect for navigating, these smartwatches display maps, offer orientation and co-ordinates, and mark locations when on the move. All of this is done by using GPS, which is one of the main features included in the watch.
  • Kids Smartwatches: A great smartwatch for kids, the come with basic functions but have a cool interface and include many educational apps and games. Very affordable and a great way to introduce children to mobile technology.
