Smartwatches can make a big difference to your wellbeing and fitness goals, bringing you vital, detailed information about your body that can help shape routine, training plan and sleep schedule. Ordinarily you need to pay a premium to land a decent one, but right now you can pick up a very well-reviewed option at Amazon for less than £45.

The Tensky Smart Watch for Women is currently £44.79 down from £89.99, and you can save another 20% by ticking the coupon option under the price. That’s just £35.83 after all the discounts. This is for the fetching pink colour - there are nine different colours in total, with slightly varying prices - all of which can go toe-to-toe with some of the big-name brands.

As you might expect, this smartwatch comes with a heartrate monitor, as well as a sleep tracker, blood oxygen monitor, and over 60 exercise modes that tailor your data to your preferred activities. Tensky promises a seven-day battery life, and it’s waterproof enough to handle rain, washing your hands, and the pool without issue — that said, Tensky also recommends avoiding wearing it in seawater and hot water.

Beyond the health tracking features, it will also pair with your smartphone to deliver notifications, control your music playback, manage calls, send calendar reminders, and compose text messages. Its companion app VeryFit is great for customising the watch to your needs, and it’s all housed under a vivid 1.8-inch screen that gives it a similar look to an Apple Watch.

Amazon customers have largely been very impressed with it, especially at this price point, with an average of 4.3 out of 5 stars from over 4,900 reviews. One person said: “Bought to replace a Fitbit Versa, I was dubious due to the price but couldn't justify the price of a new Fitbit. Not disappointed in anyway. It's better than my Fitbit was! Everything works as it should and the battery life is brilliant. Used it for 2 weeks and still on 50%. Already recommended to friends."

While another shopper said: “It does everything I need and more. Its comfortable to wear, and along with the app is easy to use. It charges really quickly and the battery lasts for days… I would definitely recommend.” And “This watch is amazing for the price,” was one of the top reviews.

“I am absolutely thrilled with this smartwatch. The 1.8" touch screen is bright and responsive, and the built-in Alexa is a game-changer for quick tasks,” said another five-star review. “Highly recommend this versatile fitness watch.”

Some users have unfortunately encountered some issues, however. One customer complained there was "not enough info in the instruction book", adding: "I still don’t know what some of the icons are for and nothing on the app to explain." Another review said: “I cannot get notifications on it that I want, as neither BBC News nor Sky News are compatible apps. This is not included in the products specifications online otherwise I would not have bought it.” App compatibility is case-by-case, although this is also true of many of the big-name brands.

Speaking of which, if you’re looking for alternatives and don’t mind spending a fair bit more, Samsung and Apple’s smartwatches are considerably more powerful, reliable and feature-rich. Right now you can pick up an Apple Watch at £399 at Currys, provided you have an iPhone to pair with it. Samsung’s premium Galaxy Watch Ultra at £599 has a bigger outlay but comes with a rugged form factor and market-leading feature set.
