Tethered to Safety.
Total Peace of Mind.
The discreet biometric band engineered for independent ageing. Continuous clinical vitals, dual-vector fall detection, and an emergency NFC passport concealed in a screenless fabric strap.
The Hidden Vulnerabilities of Independent Ageing
Ageing in place is every senior's wish, but sudden trauma, asymptomatic vitals collapse, and social isolation turn independent homes into silent hazard zones.
1 in 4 Seniors Fall Every Year
40% of fallen seniors cannot get up unassisted. Lying immobilised on the floor for hours leads to acute hypothermia, dehydration, muscle necrosis (rhabdomyolysis), and permanent loss of mobility before anyone discovers them.
Asymptomatic Collapse
Orthostatic blood pressure drops upon standing trigger sudden syncopal blackouts. Meanwhile, blunted elder immune systems suppress visible fever markers until urinary tract infections or pneumonia escalate into life-threatening sepsis.
Living Alone Without Help
Over 39 million seniors live in solitary residences without adult children at home. Elderly parents refuse to feel like burdens, while remote family members suffer constant dread that an emergency will occur while their loved one is alone.

The 7 Layers of Protection
Why Tether engineered each defensive layer—and how it translates into autonomous protection and actionable triage for caregivers and emergency responders.
Engineered for Reliability
Discreetly concealed under soft, skin-friendly woven fabric—continuous medical-grade reliability without daily maintenance chores.
Dual-Vector Fall Sensing
6-Axis IMU paired with a micro-barometric altimeter detects sudden drops with a 30-second cancel countdown.
Passive NFC Medical ID
Passive ISO 14443 chip readable at 0% battery. First responders tap their smartphone for instant triage access.
Centred Tactile SOS
A single textured safety-orange button allows blind, tactile emergency triggering with smartphone BLE calling relay.
Clinical Telemetry
Continuous optical PPG and dual precision thermistors track resting HR, blood pressure trends, and early fever spikes.
Why Traditional Wearables Fail Seniors
Smartwatches were built for tech enthusiasts; panic pendants were built in the 1980s. Neither solves the realities of independent elder ageing.
Daily Charging Anxiety
18-hour smartwatch batteries mean devices spend nights on charging docks—leaving seniors completely unprotected when 40% of falls occur.
Stigma & Screen Friction
Touchscreens cause accidental taps and confusing errors for arthritic fingers. Bulky medical alert pendants look institutional and are abandoned in drawers.
Locked Medical Data
When EMTs arrive at an emergency, critical health records, allergies, and DNR directives remain inaccessible behind passcode-locked phones.
Fitness-Only Focus
Current screenless trackers are targeted towards athletes with overly complex metrics, completely lacking dedicated fall detection or emergency response.
Family Peace of Mind.
Zero Maintenance for Parents.
The Tether App lives quietly on the senior’s phone—bridging the strap’s Bluetooth connection for automated SOS emergency calls, Find My tracking, and fall relays without requiring any daily attention.
While wearers can check their own vitals anytime, most elderly parents prefer not to manage apps. That’s why Tether enables adult children and family members to passively monitor trends, receive instant drop alerts, and stay connected from anywhere.
Silent Emergency Phone Relay
Runs in the senior’s pocket to instantly trigger 911/caregiver calls and GPS coordinates when the strap button is pressed.
Tailored Dual Interfaces
A simplified high-contrast view for elders paired with clinical-depth telemetry and Fall Radar monitoring for remote family.
Multi-Parent Switcher for Family
Adult children can monitor Mom and Dad simultaneously with seamless profile toggling.
