With an aim of going beyond simple heart rate monitoring, the Amazfit Stratos is seeking to cement its status as a premium fitness device with a variety of cutting-edge fitness and performance metrics and features powered by the integrated Firstbeat heart rate analytics engine.

“In the world of elite sport, there has been a long trend towards personalization, training based on what works best for each individual athlete,” said Aki Pulkkinen, Director of Consumer Technology at Firstbeat. “To be truly useful, a fitness wearable needs to provide feedback and information that is relevant to you, personally, and that has been achieved here.”

With the Amazfit Stratos, users can monitor trends and gain motivation with automatic cardiorespiratory fitness (VO2max) detection during running and walking activities. This information is also used to scientifically personalize training programs and to deliver guidance so that efforts can match goals.

“We are proud to have partnered with the leader in physiological analytics,” said Frederik Hermann, Head of Marketing and Sales at Huami, the company behind Amazfit Stratos. “Firstbeat’s technologies allow us to convert heart rate data into meaningful information for the user, from professional athletes to the more casual sports enthusiast.”

He continued, “Amazfit Stratos marks the launch of our new flagship multisport smartwatch with our continued focus on beautiful design, premium build quality, a competitive price point, rich feature set and long battery life.”

Amazfit Stratos and Amazfit Stratos + (Sapphire) will become available Internationally via Amazfit’s official online store at, Amazon and other channels starting on 6 March 2018 at US$199.99 MSRP and US$249.99 MSRP respectively.
