California-based smart lifestyle tech company, Renpho has announced the wide availability of its Lynx smart ring for tracking essential health metrics conveniently.
The ring helps those looking to gain deeper insight into their well-being with an always-on health tracker that delivers the Renpho Health App experience anywhere. Tracking metrics from the ring seamlessly integrate into the health app, connecting all Renpho devices within the firm’s ecosystem.
“Renpho focuses on empowering wellness for all individuals in different phases of their health journey,” said Julia Evers, head of marketing at Renpho. “With the introduction of the Lynx smart ring to our product ecosystem, we can provide users with a comprehensive understanding of their physical and mental health, taking wellness to the next level.”
The ring comes with a charging case and is waterproof up to fifty metres. It tracks a variety of health metrics, including:
- Stress levels: Wearers can see patterns and fluctuations in mood that are closely tied to their daily routines.
- Blood oxygen (SpO2): Users can view how effective their circulatory system is at delivering blood throughout their bodies.
- Heart rate: Beyond keeping a record of beats per minute and heart rate variability, the ring’s exercise report features heart rate zones throughout the day across multiple exercises, including running, walking, hiking and swimming.
- Sleep score and cycle: It analyses sleep cycles to determine user rating based on efficiency, quality and latency and shows the typical duration of sleep stages, with the cycles repeating throughout the night.
The ring (renpho.com/pages/lynx) is available on renpho.com in either a titanium or black colour finish for $200.
Founded in 2016, Renpho is creating a growing ecosystem of smart lifestyle products and is widely recognised for its smart weight scales and massage products.
