Leveraging Expertise from Medical/Elderly Care Systems for Individuals: Launch of 'Vital Navi,' a Remote Monitoring Solution Featuring a Certified Medical Smartwatch

TechnoCraft Inc. (Headquarters: Niigata City, Niigata Prefecture; Representative Director: Masanori Tsugazaka) will begin offering "Vital Navi" from April 1, 2026. This solution is optimized for individuals, enabling remote health management and vital monitoring, based on the company's expertise in systems developed for medical institutions and elderly care facilities.

**Background of Development: Growing Interest in Health Management for Elderly Parents Living Separately** In recent years, there has been an increase in people gifting practical healthcare devices to their elderly parents living separately, driven by growing concern for their health management (Note 1). However, conventional blood pressure monitors are "too troublesome to take out and thus not consistently used," and inexpensive smartwatches "cannot measure blood pressure with medical-level accuracy using green light (optical method)." Our "VitalNavi" utilizes a smartwatch certified as a medical device (Note 2), which can measure blood pressure on the wrist by automatically inflating a small airbag integrated into the watchband. This is a remote vital monitoring service. *Note 1: Source: Comparison of "Father's Day Survey (2024 Edition)" and "Father's Day Survey (2025 Edition)" from Chichinohi.jp *Note 2: Target device: HUAWEI WATCH D2 Wearable Blood Pressure Monitor Certification Number: 306AGBZI00008000

**Three Features of 'VitalNavi'**

**1. Fully Automatic Measurement with "Just Wear It": Inflates like an Upper Arm Blood Pressure Monitor** This is a medical device-certified smartwatch that can measure blood pressure on the wrist by automatically inflating a small airbag embedded in the watchband. To prevent daily measurement forgetfulness, the cuff automatically inflates at a set time to measure blood pressure. It makes it easy to record daily blood pressure fluctuations, including during the night and early morning, and is designed for consistent use.

**2. Real-time Notification of Vital Changes to Family Smartphones for Those Living Apart** Measured data is automatically shared via the cloud (our proprietary system) to the smartphone app of adult children living separately. It also includes an alert notification function for when vital data falls outside "set reference values," allowing you to monitor daily health changes even from a distance.

The accurate daily data recorded in the app can be easily shown to your primary physician, aiding in smooth health consultations.

**4. "Long Battery Life of Up to 6 Days" Reduces Daily Operational Burden** Addressing the common challenge of frequent charging for wearable devices, it offers up to 6 days of continuous operation on a single full charge, even when using features like 6 blood pressure measurements per day and various monitoring functions. Daily charging is not required, reducing the burden of monitoring and making it easy to continue use, even for those not accustomed to digital devices. Charging approximately once a week is feasible and can be coordinated with family visits, supporting a sustainable monitoring habit tailored to individual lifestyles. * (Note) Conditions for normal use: Default settings, 6 blood pressure measurements per day, 5 ECG measurements, heart rate monitoring ON, stress monitoring ON, blood oxygen level monitoring ON, message notifications ON (average 50 messages, 6 calls, 3 alarms per day), approximately 30 minutes of screen-on time per day.

**Future Development (Proposal for Gift Seasons)** This product is ideal as a "practical healthcare gift" for parents living separately, suitable for occasions such as "Mother's Day" in May, "Father's Day" in June, and "Respect for the Aged Day" in autumn. We will continue to provide information and run limited-time campaigns for each gift season, offering a new option to present "24/7/365 peace of mind through monitoring" along with your daily gratitude.
