GPS enables global positioning, useful in map, geo-tagging or navigation apps.
A heart rate monitor can help show your fitness levels, enabling you to calculate a suitable intensity of exercise.
Your blood oxygen level is a measurement how much oxygen is reaching your muscles. It is important because low levels mean that you will become easily fatigued during exercise. The more exercise you do, the better your blood oxygen levels will become.
This measures barometric air pressure. It can predict weather changes, for example a sudden drop in air pressure could mean a storm is coming. When calibrated correctly it can be used to determine altitude, which helps GPS devices to lock on quicker and with greater accuracy.
An accelerometer is a sensor used to measure the linear acceleration of a device. A common application is detecting when a device changes between vertical and horizontal positions.
A compass is useful for gaming, maps, and navigation software.
With a temperature sensor you can monitor changes in temperature to measure your exertion levels and avoid hyperthermia.
A cadence sensor measures the number of pedal revolutions per minute when you are cycling. It enables you to monitor how fast you are pedaling.
A gyroscope is a sensor that tracks the orientation of a device, more specifically by measuring the angular rotational velocity. Initially, they were built using a spinning rotor to detect changes in orientation, like twisting or rotation.

I'm using my T Rex 2 for 2 years and I'm definitely satisfied with it. The battery lasts forever and recharge fully in less than an hour. The design shows the toughness and resistance of the G-shocks, the band is comfortable, the app show everything you need, and it resists to salt water. It have the trackback option and yes, you can upload kml maps in it (but all tech sites insists that ir can't). It have a password when you remove it from you wrist, but the bad thing about it is that eventually the password came back even in your wrist. Other bad thing is that I can't buy anything in the store. I've sent a lot of emails to the support but I didn't have and answer. But, in general, it's a very good smartwatch, with all you'll need indoor or outdoor.

Up to today, I've had it for 4 months, and the feature I like most is the track back for my job. I work in mining, and I'm in areas where there is no signal, and the GPS does its job excellently. Everything else performs its function well. For the price, it's great. I'm waiting for the Zepp OS 2.0 version this August 2023... I see it says it has body temperature measurement but it doesn't, hoping this is corrected in the comparisons.

Ultra é uma evolução, mas não justifica o preço.

O t rex representa uma boa evolução, porém não justifica o preço cobrado em comparação com o t rex 2, que hoje pode ser comprado por aproximadamente 40% do valor do t rex ultra. As diferenças mais expressivas são o acabamento em titânio, maior detalhamento dos mapas e a memória de 3gb para músicas. As outras mudanças são todas sutis e não representam exatamente um avanço.
