He has started running and walking, and plans to ski and swim. Anow you want to start mapping your adventures, compiling data and measuring your heart rate, and for high-altitude travel, even your SpO2 (oxygen saturation) levels. It may have a pretty jaded industrial design, but the Amazfit T-Rex Pro can do it all and more.

It has a hundred sport modesFrom running and walking to snowboarding, rock climbing and cross-country skiing, it can automatically notice most of them. It has GPS so it can map your run (although that won't help you navigate). It is also water resistant to 100 meters. The battery life can reach 18 days, despite its bright and colorful 13-inch AMOLED screen.

For the low cost, that's quite a feat, plus Is it a rugged fitness tracker or a smartwatch?

The T-Rex Pro will also give you a finely textured readout of your night's sleep.

Amazfit T-Rex Pro Review | Comparison 1

Then, Why are we not fully convinced of the T-Rex Pro? Created by the Chinese brand Zepp Health, previously Huami, the T-Rex Pro summarizes a myriad of data. Sure, it's free on the Zepp app, but aside from being able to post your latest workout to social media, there's not much you can do with that data. So if you're using smartphone apps like Strava or MyFitnessPal to track your activity and/or diet these days, you'll have to live with 2 silos of data that don't integrate. And that seems to be a stumbling block to asking for auxiliary activity data in the first place.



You're going to be hard pressed to find a better value, rugged sports watch that covers the basics of running, biking, walking, and more.. Despite its many positives, we're not entirely convinced that the T-Rex Pro is splendid enough with its data to be considered the best in its class.

Price and launch date of Amazfit T-Rex Pro

  • outside now.
  • It costs $179.99 (about €139, AU$249)

The T-Rex Pro was launched in the month of March 2020 for $179.99 (roughly €139, AU$249). In the US it's available direct from Amazfit, while in the UK it's available from Argos or Amazon. colors: meteor black, desert green and steel blue.

Amazfit T-Rex Pro design

  • Bulky design
  • One-inch three-inch AMOLED screen
  • Silicone rubber strap

You get a lot of features for your money with the T-Rex Pro, but a "wow factor" isn't one of them. The T-Rex Pro looks pretty much exactly like the original Amazfit T-Rex. This new version also has 4 screws on the bezel for a practical, industrial and slightly plastic look.

There are also 4 metal buttons (trend, back, top and also bottom) on the edge of the box that are large enough to simply press on while running or wearing gloves. Too simple, indeed, making casual pressure inescapable.

Look at it with a radius of 47.7mm and a thickness of 13.5mm, the T-Rex Pro is a thick polycarbonate product that has a somewhat masculine look, but its slim 59.4g means it doesn't feel heavy when worn. Zepp claims that the T-Rex Pro is impact resistant, can withstand -40°C to 70°C, is resistant to salt spray, and is MIL-STD-810G compliant, though by far its rugged feature most essential is that it is waterproof up to 100m. This is double what the original version was capable of.

The T-Rex Pro is built around a 13-inch AMOLED touchscreen. which has a resolution of 370 x 370 pixels (again, as above). It's just noticeable in direct sunlight, but only if you set it to its maximum brightness level. Not surprisingly, this affects battery life, which Zepp estimates at 18 days. In practice, its 390 mAh battery lasts around a week, which is still impressive.

It comes with a 2021mm wide silicone rubber strap that is comfortable and stays in place while you run. The only other accessory in the box is a unique charger that attaches magnetically to the bottom of the box. This is where you'll find the flashing LEDs on Zepp's new 2 Bio-Tracking XNUMX PPG optical sensor, which measures heart rate and SpOXNUMX (oxygen saturation). Also inside there is an accelerometer, gyroscope, altimeter, geomagnetic sensor and ambient light sensor.

Long story short, he's a data collection enthusiast.

Amazfit T-Rex Pro setup

  • Arrives absolutely loaded
  • Links to Zepp app easily
  • Customizable watch faces and screen savers

Although the T-Rex Pro is supposedly a fitness-oriented watch, it also has certain smartwatch-like quirks.. It's far from "the ultimate personal assistant," as the manufacturer claims, but it can be set to haptically sound on incoming texts, calls, and reminders. You can also exercise basic control over the music on your phone.

Connect it to a smartphone via Bluetooth, a simple task, and you will also get a forecast of the weather, the times of sunrise and sunset and the current moon phase.

The tempered glass touchscreen is sensitive enough, which makes the T-Rex Pro a pleasure to use on the go. Small face-up and face-down swipes toggle between the watch face and the shortcut control panel, where you can do everything from turning on the flashlight (which isn't bright enough for practical use) and activating the power saver modes. power / don't bother, to choose a screen saver and adjust the screen brightness. It is also possible to configure the screen so that it is always and at all times on throughout the established times.

While Zepp claims the T-Rex Pro has a battery life of up to 18 days, it's been made clear that this only applies if you truly don't exercise. However, if you exercise for an hour every day and stick with it on purpose, you can expect the T-Rex Pro to work for a week or so.. A little less if you customize the T-Rex Pro to say, make a haptic buzz every time you run a mile, or set the screen to full brightness and "always on."

Amazfit T-Rex Pro Fitness Tracker

  • Data is clearly presented
  • Accurate heart rate monitoring
  • Reliable GPS location tracking

Although this is a more capable version of the original T-Rex that we examined last year, in the same way as its predecessor, The T-Rex Pro is a high-end, high-performance smartwatch alternative that isn't without its limits.

Arguably, the T-Rex Pro packs more features than it should for its low cost. For everyday use, its GPS and heart-rate monitoring are surely the most essential, and both worked well throughout our fortnight's test. Alerts your heart rate every 10 minutes at rest and continuously throughout activity. GPS tracking, which uses GPS, GLONASS, Galileo or BeiDou satellite positioning, was flawless in our tests.

So throughout and after a run, you'll get at-a-glance data on elapsed time, calories burned, your average heart rate, and even finer details like cadence, average stride, speed, shifts, altitude and heart rate zones. As soon as you have completed a run, the T-Rex Pro will give you a recommended restore time.

It also gives you a VO2 max reading. Hey? This is the maximum amount of oxygen in milliliters that can be used in one minute per kilo of anatomical weight. And so? The same is true of your data on the effect of aerobic training, the effect of anaerobic training, and training load, which are not going to mean anything to most people either.

We also estimate that the SpO2 (oxygen saturation) readings are new and not truly relevant, unless you are walking at altitude and are suspicious of altitude sickness. There is too much data here and not enough interpretation and goal setting / virtual training.

There are 2 ways to track your activity; let the T-Rex Pro warn you automatically, or physically press the mode button and scroll down to your planned activity, such as outdoor running, walking, treadmill, trail running, indoor walking (to name just 5 of the XNUMX listed activities, although you can add more manually).

In our tests, the T-Rex Pro was able to decipher between running outdoors and strolling, but it was found to be less efficient with other activities. So it is better to tell him precisely what he is about to do.

One frustrating issue we did have was how impractical the button layout was for traversals. The "choose" button on the right side of the watch is too simple to accidentally press while using a sleeve on the T-Rex Pro, interrupting your training. You're not likely to wear the T-Rex Pro up your sleeve when you're running, sport isn't a huge inconvenience every single day, but when you're walking around in a jacket it's pretty much inescapable. The result is incomplete data and there is no simple solution.

The T-Rex Pro is also not the perfect bed partner. It has a vibrating alarm clock, but instead of a slight haptic buzz or 2, you get robust streaks that don't release for twenty seconds. Then everyone in your bed will also wake up.

Amazfit T-Rex Pro companion app

  • It clearly presents biometric and cartographic data
  • Collect data from other Amazfit devices
  • Does not integrate with third-party applications

The T-Rex Pro is linked to the brand's free Zepp app, with which he syncs up a little once an activity is finished and brings it closer to his smartphone. It's very simple to see your current heart rate, step count, SpO2 levels and previous training records, presented in a clear and colorful way.

However, we would also be disappointed in the 'my goals' section of the app, which is simply an end to daily steps, a target weight, an end to burn calories and an end to sleep. All this is somewhat basic considering the esotericism of the data that seems obfuscated to summarize.
