Product Overview

The V3 is a cost-effective, screen-free smart ring constructed with polished stainless steel housing, built for basic all-day wellness monitoring. Since it is worn on the finger, it avoids the bulk of traditional wrist smartwatches and can stay on during daily routines and sleep. It relies on Bluetooth 5.0 BLE to sync biometric data to mobile devices, while its integrated PPG sensor suite captures core lifestyle health metrics. In addition, the supporting portable magnetic charging case extends the total cumulative usage time. However, this model has no touch gesture controls or NFC module. It also does not include speaker, microphone or vibration hardware for incoming calls and message alerts, with no support for ECG, blood pressure trend, stress index or female cycle tracking. All biometric readings, activity logs and long-term trend visualizations appear exclusively inside the paired mobile wellness application.

Target End Users

Adult male and female consumers looking for an affordable low-profile wearable. Their core needs include continuous heart rate, blood oxygen and skin temperature tracking, automatic sleep stage recording and light fitness activity logging, without extra premium features such as touch gesture or NFC.

Target Wholesale Buyers

1. Distributors specializing in entry-level health wearables and budget smart ring product lines
2. Corporate procurement teams sourcing economical wellness bulk gifts for employee health programs
3. Private-label brands launching basic smart ring collections for mass-market lifestyle tracking

Core Hardware Specifications

2.1 Form Factor & Exterior Finishes

• Wearable type: Finger-worn polished metal screen-free smart ring
• Sizing: Multiple inner diameter physical ring sizes to accommodate different finger circumferences
• Available surface finishes: Black, Silver, Gold, Rose-Gold
• Control method: No touch-sensitive gesture controls
• Operation note: No on-board screen; all data visualization and biometric analysis take place in the companion mobile app

2.2 Integrated Sensor Hardware

• Optical sensing: PPG optical sensor suite for continuous vital sign sampling
• Temperature sensor: Skin surface temperature detector
• Motion sensing: Built-in accelerometer to detect body movement, sleep status and daily activity

2.3 Wireless Connectivity Module

• Radio: Bluetooth 5.0 Low Energy (BLE)
• Functional limitations: No built-in NFC module and no touch gesture controls. Furthermore, there is no onboard speaker, microphone or vibration hardware, so the ring cannot support two-way calling, audio playback or message vibration alerts.
• GPS note: No standalone GPS chip. Activity route tracking depends entirely on GPS signals captured by the paired smartphone.

2.4 Power & Charging Hardware

• Cell type: Miniature 20 mAh lithium polymer battery optimized for low-power BLE sensor operation
• Primary charging method: Custom magnetic contact charging dock for single ring recharge
• Extended power accessory: Matching portable magnetic charging case to extend aggregate usable time
• Runtime performance: Single ring delivers approximately 5–7 typical days of continuous use. Actual battery life varies based on sensor sampling frequency.
• Safety protection: Multi-layer circuitry prevents overcharging, over-discharging and minor internal short-circuit risks

2.5 Enclosure & 5ATM Waterproof Rating

• Waterproof standard: 5ATM (ISO 22810:2010) dust and water resistance
• Operational limits: Supports hand washing, daily showering and shallow cold-water swimming. On the other hand, it is not suitable for deep diving, hot springs, saunas or high-pressure water jet cleaning. Internal sealing gaskets degrade naturally over extended use and gradually reduce water resistance over time.

2.6 Cross-Device Compatibility

The V3 maintains stable BLE pairing and full tracking features with two mobile operating systems:

• Android 8.0 and newer Android smartphone releases
• iOS 9.0 and subsequent iPhone versions All biometric sync and historical trend analysis run through a unified multi-language wellness mobile application.

3. Sensor & Wellness Tracking Functions

Mandatory Non-Medical Critical Disclaimer

All heart rate, SpO2 and skin temperature metrics produced by this smart ring serve solely for consumer lifestyle wellness reference. This device is not certified medical diagnostic equipment. It cannot be used for disease diagnosis or medical treatment decisions. If users experience persistent physical discomfort or cardiac symptoms, they must consult licensed medical professionals immediately.

3.1 PPG Multi-Parameter Vital Monitoring Suite

• 24-hour automatic continuous heart rate sampling with manual spot check capability
• Real-time SpO2 blood oxygen measurement for resting and post-activity recovery assessment
• Continuous skin temperature tracking to record shifts in physical condition
• Verified lab baseline heart rate measurement accuracy exceeds 97%. Nevertheless, real-world readings may shift based on ring tightness, finger skin condition, body motion artifacts and ambient temperature fluctuations.

3.2 Multi-Stage Overnight Sleep Recording

The ring automatically detects full-night sleep cycles, separating records into light sleep, deep sleep and REM sleep phases. It stores simplified sleep summaries locally and synchronizes full sleep archives to the app’s cloud storage when BLE reconnects to the paired smartphone.

3.3 Activity & Light Sport Logging

• Built-in step counter and multiple light fitness sport profiles for daily activity tracking
• Offline local storage saves workout duration, step count and calorie consumption without constant phone connection
• Once BLE pairing resumes after outdoor activities, all offline fitness records automatically sync to the mobile app cloud.

3.4 Unsupported Specialized Tracking Modules

This entry-level metal wellness smart ring omits dedicated hardware and firmware for the following functions:

1. Built-in screen for real-time on-ring data viewing
2. Touch gesture control system
3. NFC tap trigger module
4. Speaker, microphone and vibration motor for calls and message notifications
5. Single-lead ECG snapshot capture hardware
6. Blood pressure trend estimation algorithm
7. Stress level assessment algorithm
8. Female physiological cycle health tracking reminders and data logging

4. Mobile App Cloud Ecosystem

• Bidirectional BLE data synchronization between the V3 smart ring and multi-language wellness mobile app
• Secure permanent cloud storage for all historical datasets: heart rate, SpO2, skin temperature logs and sleep & activity records
• Automatically generated weekly and monthly wellness trend reports to help end users observe long-term physical and sleep patterns
• Cloud backup prevents permanent loss of accumulated biometric and activity tracking archives
