The Amazfit GTS 3 is the update to the Amazfit GTS 2, a foursquare smartwatch that sits in the brand’s style scout range. It promises to evangelize smartwatch and fitness features in a stylish package for less than £150/$150.

Like the Amazfit GTR 3 Pro and the GTR 3 that were launched alongside it, the GTS 3 runs on Amazfit’s new Zepp OS operating arrangement. This seeks to bring Amazfit watches closer in line with the likes of the Samsung Galaxy Spotter 4 and Fitbit smartwatches, by providing access to apps both of the native and third-political party variety, forth with improvements to the overall software experience.

That toll tag puts the Amazfit GTS 3 up against smartwatches such as the Fitbit Versa two, and comes in cheaper than an Apple tree Watch Serial three. Amazfit has fabricated great progress with its smartwatches in contempo years, so is Zepp Os the missing ingredient to complete that puzzle of creating a neat smartwatch?

Blueprint and Screen

  • Slim, square aluminium design
  • Well-baked AMOLED screen
  • Available in three colours
  • Waterproof up to fifty metres

Amazfit continues where it left off with the GTS 2, sticking with a square design that doesn’t sit down hulking on the wrist, nor does it feel it either.

Hither, you get a 42mm watch example with curved corners, made from an aluminium alloy and available in your choice of Graphite Black, Ivory White or Terra Rosa colours. I had the black version in for review, paired with a 20mm-sized silicone strap that uses a quick-release set upwards to brand information technology easy to switch out other straps.

It’southward a lovely looking lookout man overall, which displays a svelte, minimalist feel that nigh belies the fact it costs less than £150/$150. It doesn’t feel inexpensive, the weight is nice and at 8.8mm thick, information technology’s past no means a chunky fauna, which is welcome.

To accept control, there’s but a solitary physical button compared to the two you get on the GTR 3 and GTR 3 Pro. Information technology looks similar a traditional watch crown and can be pushed to wake upwards the screen, plus you tin twist to rotate and scroll through menu screens also. However, virtually of your interactions will exist through taps and swipes of the one.75-inch, 390 x 450 Ultra Hard disk drive AMOLED screen, which delivers a bump up in screen size and resolution on the GTS 2.

Amazfit has done a sterling job of putting high-grade displays on its affordable smartwatches and this carries through to the GTS three. It displays the lovely deep blacks you’d associate with a good-quality AMOLED. Colours are accurate, too, and information technology’due south sharp and fairly vivid to view indoors and outdoors. The screen is also nicely responsive to taps and swipes, and there are no worrying signs of lag when yous’re booting upwardly features and modes such every bit workout tracking.

You can use information technology in an e’er-on mode, or even schedule when that always-on fashion is in utilise, to ensure information technology’s engaged when you most need it.

On the durability front, the GTS 3 is waterproof upwardly to 50 metres, which makes it suitable for employ in a pool and in the shower. I’ve taken the GTS iii for a swim and can confirm that it’south comfortable to article of clothing in the water; it doesn’t weigh heavy while swimming at all.

The GTS iii’s design is definitely a huge plus indicate in my eyes. It’southward a smart-looking smartwatch that keeps things unproblematic in the nicest way. It comes packing a corking screen, too, and you even have the choice to switch out the straps.

Features and Performance

  • Zepp OS
  • Two smart administration
  • Misses Wi-Fi and speaker from Pro model

Like the GTS 2, the GTS three is a smartwatch that you tin can utilise with both Android handsets and iPhones – mine was paired with the former. Overall, the GTS 3 has been stress-free to use, with no major problems to study.

To become things set up, yous need the Zepp companion app – which, thankfully, has received a bit of a spit and polish. Information technology features a homepage to view your health and fitness stats and an area from which you can arrange watch settings such as enabling notifications, advanced health monitoring and accessing picket and app stores.

That brings me nicely to Zepp OS, which is Amazfit’s movement to offer a more fully fledged smartwatch feel. The company is promising a slick UI feel, with the improver of an app store from which you tin can download mini apps, with a third-party app for calculation smart dwelling controls. Amazfit is besides working on a spider web-based app developer kit to bring more apps and watch faces into the fold.

The app shop lives only in the companion app, and information technology’s perchance generous to call it a shop since it doesn’t come anywhere shut to rivalling the Apple App Store or Google Play Shop in terms of what you can download. I downloaded mini apps such as a toothbrush timer and a calculator, just in that location are no big-proper noun apps to be plant, which I was hoping to see.

The Zepp OS experience on the watch at least is a positive one. It remains heavily gesture-based, having you swipe from all directions of the principal watch face up screen to navigate, and using the physical push to access the apps list. It won’t take y’all too long to familiarise yourself with the GTS iii.

You lot become a fair number of central smartwatch staples here. Y’all can view notifications, only you tin’t respond to them. Amazfit offers its offline voice banana using a built-in microphone to evangelize hands-free control of features such as launching music playback controls, and Amazon Alexa to ask queries once your account is linked in the Zepp app.

You are defective some features included with Amazfit’s GTR iii Pro, however. At that place’southward no speaker, which ways you won’t be able to accept calls over Bluetooth. There’s no Wi-Fi connectivity, which is tied to the fact that there’s no congenital-in music thespian hither. In that location’s no back up for payments or LTE cellular connectivity hither, either.

Amazfit GTS 3 Amazon Alexa and the weather

At least the features that do brand the cutting piece of work well. Notifications appear promptly and are nicely optimised for the GTS 3’s foursquare display. Music playback controls worked effortlessly when I played Spotify playlists on my telephone, and the offline voice banana and Amazon Alexa assistant are surprisingly responsive to commands. In that location’due south even a useful list of things you tin can ask the offline version hidden in the watch settings.

The app store element that Amazfit offers via Zepp OS is clearly still very much in its early stages– and I’d promise that things will chop-chop improve on that forepart. Although similar Samsung, Huawei and Fitbit have found, this is no mean feat. Thankfully, Amazfit has a smartwatch that’due south easy to apply, shows no real signs of functioning bug, and has the potential to grow every bit a smartwatch platform.

Fitness Tracking

  • Over 150 sports tracking modes
  • Supports five satellite systems for outdoor tracking
  • Automatic exercise recognition for 8 activities
  • VO2 Max and additional grooming insights

From a software indicate of view, Amazfit has always been seen as prioritising its health and fitness tracking features. While it doesn’t include serious health monitoring tools such as an ECG sensor or the ability to monitor blood pressure, its offer will let you to track runs, metrics such as middle rate and blood oxygen levels, plus daily stress levels.

On the sensor front, in that location are the typical movement sensors to track movement indoors and for activities such as pool swims. There’due south a barometric altimeter to measure out elevation and a temperature sensor to detect pare temperature changes, although the data generated didn’t experience hugely reliable.

Amazfit uses a BioTracker 3.0 biometric sensor to monitor heart rate 24/7 and through practice, along with unlocking 24/vii blood oxygen monitoring. Doing the latter volition have an adverse impact on bombardment life, though, so go on that in mind.

The GTS 3 besides includes the one-tap measurement characteristic included on the Amazfit GTR iii Pro, letting yous monitor center charge per unit, stress, breathing charge per unit and blood oxygen with a single 45-second measurement.

You also go the same 24/7 fitness tracking and slumber monitoring support as the GTS ii, and that means PAI Wellness Assessment scores are available to ensure you regularly enhance your heart rate through practice.

When it comes to sports tracking, there are more than than 150 modes at your disposal – but only a portion of those will offer metrics across tracking conditioning duration and heart rate. In that location’s automatic exercise recognition for eight activities including running and walking, plus back up for the v cardinal satellite systems to offering accurate outdoor tracking for activities such as runs and outdoor cycling sessions.

Amazfit GTS 3 awards and badges

Amazfit is now looking beyond tracking exercise, delivering the kind of insights you lot’d usually acquaintance with Garmin and Polar sports watches. Its new PeakBeats grooming insights will analyse your workout data and key metrics to inform recommended recovery time, providing an indication of just how fit you lot are.

Every bit a smartwatch for monitoring health, fitness and tracking practice, I’d definitely say that the GTS three does a solid job overall – but there’s room for comeback on the accuracy front.

It’s fine for counting steps, for example, and y’all have a dedicated scout widget to follow progress. For sleep tracking, the GTS iii is a comfortable spotter to sleep with and it delivers a good array of sleep metrics. All the same, note that I found information technology tended to record a longer slumber duration by one-ii hours compared to a Fitbit Charge 5, Oura Band and Whoop four.0.

There’southward good and bad news with continuous heart rate monitoring, too. Resting heart rate data largely matched upwards to those three devices mentioned above, although boilerplate heart rate recorded by the GTS 3 was usually 20bpm college in comparison.

Information technology’south a similar story for sports tracking. I used it for HIIT workouts and indoor rowing sessions, finding that average and maximum center rate data was significantly higher than a Wahoo Tickr 10 chest strap monitor. For outdoor runs, it came up a piffling short on altitude tracking, simply average middle rate and maximum centre rate data seemed a trivial more reliable for steady-paced runs. Throw in some loftier-intensity time and the sensor started to evidence signs of a struggle, withal.

That inconsistency with middle rate monitoring during exercise throws some doubt over the reliability of the new PeakBeats preparation insights, which I definitely call up you should use as loose guidance – whether yous’re new to tracking exercise or a seasoned tracker.

Battery Life

  • half-dozen days of heavy use is accurate
  • 12 days in typical use seems optimistic
  • Skilful 20 hours of GPS battery life

The GTS 3 substantially promises anything from a calendar week to over a couple of weeks of battery life, depending on the features you use and how regularly you utilise them.

Amazfit breaks downwardly battery life as 12 days with typical use, up from 7 days on the GTS ii. It’s 6 days with heavy use (up from 3.v), offer the aforementioned twenty days when using the more than restrictive bombardment saver mode. If you’re using GPS tracking on a regular basis, Amazfit claims you can get 20 hours of GPS battery life, which puts information technology in good company with pricier sports watches.

Amazfit GTS 3 - app selection screen

My time with the GTS iii definitely saw information technology veer into heavy use, using the brandish in a mix of always-on and standard modes, enabling notifications, monitoring centre rate and blood oxygen continuously, and using the GPS to track outdoor workouts. This saw the GTS 3 run for effectually 4-five days. For an hour of running, the battery drop off was around viii-9%.

It’southward conspicuously a smartwatch that has the capability to last a week without charging. Steer articulate of the more power intensive features – such equally the e’er-on display mode and continuous blood oxygen – and you’ll comfortably see the GTS 3 last over a week, peradventure longer.

Amazfit uses the aforementioned-style charging cable as the GTS 2 to power upward, which takes effectually ii-ii.five hours to go from 0-100%. Unfortunately, there’south no fast-charging support for quick acme-ups here.

Latest deals

Should you buy it?

If you desire an affordable, foursquare smartwatch
There are plenty of square-faced smartwatches available in at the GTS three’s price, simply this ane definitely stands out for the right reasons.

If you care nigh heart rate information
Unfortunately, while the GTS 3’s biometric sensor is capable of delivering reliable center data, it struggles where it actually matters. For more authentic monitoring, look elsewhere.

Terminal Thoughts

The Amazfit GTS 3 is a adept-looking smartwatch at a very expert cost. It offers a decent mix of smartwatch and fitness features that, on the whole, work really well. If you want the best you can go far those departments, yous’ll need to spend more, however; Zepp’s OS and app store is far from fully formed compared to other smartwatch platforms. That being said, if you around the £150/$150 mark to spend and would similar an attractive pick that’s easy to apply and offers a nice, slick operation, there’s still plenty to like here.
