The Differences?
The differences between GTS and GTS 2 is that the latter comes with 4GB storage capacity, a microphone and loudspeaker than enable voice assistant via Alexa, the ability to make and receive calls from the watch when the phone is nearby, and features blood oxygen tracking – all of which the GTS lacks.
However, while GTS 2 is tested to last up to 7 days with mixed usage, GTS will last up to 14 days.
What’s New?
Although the GTS 2 retains the same shape and appearance as its predecessor, both smartwatches will track all the basics like your steps, heart rate, sleep, calories, and will help you manage notifications. However, GTS 2 comes with new features that make it a better smartwatch.
- 4GB Music Storage on GTS 2
- Microphone and Loudspeaker Have Been Added to GTS 2
- Bluetooth Calling on GTS 2
- Alexa is on GTS 2
- Blood Oxygen Tracking
The GTS 2 comes with a 4GB storage capacity that allows you to store your favorite tracks on the watch. You can add content easily to the GTS 2 from the Zepp app.
Unlike GTS, GTS 2 comes with a microphone and loudspeaker that will allow it to make and receive calls, and you can play media files aloud, as well as access voice assistant via Alexa.
As a result of the presence of a microphone and loudspeaker on GTS 2, you can make and receive calls directly from the watch when the connected phone is nearby.
Alexa voice assistant has been added to GTS 2 which will allow you to do simple tasks like using your voice such as to set an alarm, check the weather, and more. Alexa will be added to GTS 2 via an OTA update in the future.
GTS 2 features a blood oxygen app that allows you to measure your blood oxygen levels. This will allow you to see how well your blood absorbs oxygen.

Blood Oxygen Tracking without having a Pulse OX? How?
There is no Pulse oximeter in GTS 2 and GTR 2, what is available is an SpO2 blood oxygen app that measures blood oxygen saturation based on readings from
Huami self-developed BioTracker 2 PPG sensor.
