Buyer’s Guide

With Apple’s recent release of the watchOS 5, many people are becoming curious about smartwatches. When it comes to what a typical user may want from their device, there is no one-size-fits-all approach as different models offer various features such as cellular connectivity and extended battery life.

But for those who do not need any specific functionality offered by these additional options or simply don’t care that much about having fitness tracking capabilities on their wrists (or running multiple apps), you can save money with some cheaper alternatives available which still provide plenty in terms of productivity software and security measures thanks to its Bluetooth connection.

Standalone or Tethered?

When it comes to the world of smartwatches, there are two types: 

  • Tethered smartwatches
  • Standalone smartwatches

Tethered smartwatches

You might be wondering how a tethered smartwatch is any different from the old-school, “dumb” watch. The answer? They rely on Bluetooth to connect with your smartphone and share some of its functions! That’s not all though; you have to keep it within range for things like messaging alerts or phone calls.

Standalone watches

Standalone watches instead use their own SIM card or eSIM to function independently of a phone. You no longer have to worry about not having your cell when you want it, because standalone cellular smartwatches now exist. They feature 4G LTE and can make voice calls without needing the nearest mobile device!

Cellular-enabled smartwatches are excellent tools for life on the go, helping us keep in touch with others whilst reducing our reliance on smartphones. These types of watches feature WiFi and/or wireless 3G, 4G, or LTE technology so they can connect to networks wherever we may be.

Battery Life

Smartwatches have to be charged on a regular basis, but some can last up to 30 days without needing to charge again. That’s because they’re powerful devices with processors and screens – no different than standard watches which usually only need new batteries every few years.

For a light user, it is recommended to charge once every week whereas for someone who exercises daily with the watch and uses various features like phone calls or listening to music on their wrist they will need more frequent charging.

User Interface

Technology has shrunk so much in the last decade that it’s now difficult for users to interact with their devices. However, clever interface design can make a world of difference between frustration and intuitive ease-of-use when interacting with your device. Apple and Samsung watches are excellent examples of this phenomenon; if you want an easy time using technology then buy one!


Since smartwatches can be pricey, you should establish a budget to know what you’re willing to spend on one. By setting yourself limits for cost and features, it will help narrow down your options so that way when picking out the right watch for you, not too many unnecessary bells and whistles are included with an expensive price tag. You want this purchase to work towards meeting your needs instead of leading them astray by overspending unnecessarily.


What can a Cellular Smartwatch Do?

A cellular smartwatch is the best of both worlds – it functions as its own phone for wireless services, like maps and calling. It also provides a convenient way to stay in touch without having your phone on you at all times! Cellular watches are perfect for busy people who don’t want their phones with them constantly but still need easy access to important features and apps. With Apple Pay or Google Pay integrated into most new models, these devices make transactions easier than ever before? Why not get one today?

Track your fitness, diet, and sleep with an all-inclusive tracker. These devices can also be used for hands-free calling while driving or listening to music on Bluetooth headsets when you’re in transit.

Do you need to switch your SIM card over?

If you’re looking for a way to cut the cord, then embedded SIM cards are an excellent option. These SIMs allow your smartwatch and phone to share data limits on one carrier plan while still maintaining separate call/text plans. Your eSIM-enabled device will “bolt” onto your existing mobile network with no need for physical components such as adding another external chip or card that can get lost in transit; all it needs is power from its battery source!

Some newer models like Google’s Pixel 3 have built-in support for this feature (though they lack other features offered by competitors).

Is Smartwatches Easy to Use?

The rise of smartwatches has been to no surprise. With high-definition screens and responsive touch, it’s easy for users to navigate through their device with ease. Whether you choose a watch that uses a rotary bezel or side-swipe navigation, the interface is user-friendly and intuitive.

When it comes to ease of use, your preference for either an Android-based system or iOS will depend on how you’ve used them in the past. If you have experience with Apple devices before then they are a great choice because their intuitive user interfaces make things easier and allow people to get accustomed more easily.

Are Smartwatches Built to Last?

Smartwatches are great for everyday use, but they’re not invincible. Some smartwatch screens can only resist scratches from a knife or pen and other dust particles while others have an IP rating that measures how much water they can be submerged in without being damaged (if at all). All of these factors make it interesting to find the best watch for you!


With the latest in technology at their fingertips, we know you’re going to find your next favorite smartwatch. The Apple Series 5 is our top pick thanks to its sleek design and amazing features that make it stand out from the pack! If you are looking for something a little more affordable (and don’t mind saving on battery life) there’s always Samsung’s Ticwatch Pro available here too – this watch will save some cash while still providing all of those helpful health insights like step count, sleep duration, water intake levels, etc.
