The Differences
The difference between GTR and GTR 2 is that the latter features a SpO2 blood oxygen app and comes with onboard music storage, a microphone, and a loudspeaker that enables Bluetooth calling as well as Alexa voice assistant. However, the GTR has a longer battery life than GTR 2.
- Design
- GTR 2 Has Music Storage
- Fitness Tracking
- Battery Life
Nothing much has chnaged in apperance with the release of GTR 2, it reatins same circular shape as its predecessor. And also has same 1.39 inches AMOLED display and 454 x 454 resolution. The only slight difference in design between these two is that while GTR comes in 47mm and 42mm, GTR 2 comes in one size and available in two materials stainless steel and aluminum. Although, the 47mm model of GTR is available in three materials; stainless steel, aluminum and titanium materials.
Both GTR and GTR 2 have a 5ATM waterproof rating which makes these two swim-proof and safe to wear while swimming.
Huami has added onboard music storage to GTR 2 which will allow you to store your favorite tracks on the watch. It also has a microphone and loudspeaker which GTR lacks, this enables you to make and receive calls from the GTR 2 via Bluetooth connection to a paired phone. Alexa voice assistant will also come to GTR 2 which will allow you to use your voice to do simple tasks like setting up the alarm, checking the weather, and more.
GTR 2 also features an offline voice assistant that will allow you to play music on the watch and do other related tasks with your voice.
In terms of fitness tracking, both smartwatches are equipped to track your heart rate, sleep, steps, calories, and have inbuilt GPS for outdoor activity tracking, and both smartwatches feature 12 preloaded sport modes.
However, GTR 2 has an improved Huami self-developed BioTracker 2 PPG sensor that supports the blood oxygen app which allows you to measure your blood oxygen levels. You can also measure and manage stress with the stress app on GTR 2.
Perhaps the price to pay for the additional features on GTR 2 is that it has a shorter battery life compared to its predecessor. Although with a higher 471mAh battery capacity, GTR 2 is tested to last up to 14 days on mixed usage while GTR 2 can last up to 3 weeks. Meanwhile, GTR 42mm has over 10 days of long battery life.
Which is Better?
The GTR 2 is certainly a better smartwatch than its predecessor. It features music storage, Alexa voice assistant, Bluetooth calling, and more fitness tracking features which makes it a more comprehensive smartwatch than GTR.
However, GTR is a fantastic smartwatch.
