Frequently Asked Questions for B2B Buyers & Distributors
Technical guidance and commercial policies provided directly by the FITVII product development team.
How does the optical PPG sensor estimate sleep phases accurately?
FITVII smartwatches use multi-wavelength optical sensors to continuously track micro-fluctuations in blood volume at the wrist. By combining heart rate variability (HRV) analysis with movement frequency captured by 3-axis motion sensors, the algorithm calculates autonomic nervous system status to categorize sleep into Light, Deep, and REM stages.
Can FITVII sleep tracking devices diagnose Sleep Apnea clinically?
No. FITVII health smartwatches provide non-invasive wellness trend estimates and nocturnal SpO2 monitoring for everyday awareness. They are not clinical diagnostic medical devices. Wearers who experience severe oxygen dips or persistent fatigue should consult a certified medical professional.
What are the typical lead times and shipping options for bulk wholesale orders?
Standard inventory orders ship from our primary warehouses within 2–5 business days via express air freight (DHL/UPS/FedEx) or dedicated logistics routes. Custom OEM production runs typically require 15–25 business days depending on customization specifications and order volume.
Are there any ongoing software fees or app subscriptions for end-users?
No. FITVII companion apps are completely free to download and use on both iOS and Android platforms. All health tracking, sleep metrics, and family sharing features operate without any monthly subscription charges, creating high long-term consumer satisfaction.
FITVII smartwatches are designed for general wellness tracking, sports activity management, and daily baseline reference. They are not intended for medical diagnosis, treatment, prevention, or clinical disease management. Always consult qualified healthcare providers regarding health conditions.
