Amazfit GTR 2 VS Amazfit GTR 3 & 3 Pro? Which one best for you?

The Amazfit range covers the basics when it comes to 24/7 activity and sleep tracking. What you need most, including stress and blood oxygen tracking.

Sleep statistics, in particular, are very detailed. The SomnusCare Sleep engine on the GTR 3s remains the same as that of the previous generation. In addition to your overnight stats, it monitors the quality of naps and sleep breathing over 20 minutes. RealBeats 2 monitors heart rate with 98% accuracy. It also produces high and low heart rate alerts.

What’s new on the GTR 3 watches is the one tap measurement. Thanks to the Biotracker 3.0 engine, in just 45 seconds the device can read your heart rate, SpO2, stress and breathing rate – all at the same time. This is for on-demand reading.

More exciting than that is the ability to continuously measure blood pressure. The functionality is not currently available. Zepp Health is currently awaiting regulatory approval for its Pumpbeats blood pressure engine. Once the CE and FCC certification is secured, the functionality will be rolled out via a firmware update. But we are told that this is a very strict and complicated process so there are currently no clear plans as to when (or if) this could happen.
