FallGuard keeps your family safe by detecting falls and streaming live vitals from your loved one's Apple Watch to your phone — instantly. ALERTS THAT GET THROUGH A fall alert can reach you even when your phone is silenced or in Do Not Disturb. Most apps go quiet at night — the one time a fall is most likely to go unnoticed. FallGuard doesn't. You'll be asked once whether to allow this, and you can turn it off anytime. LIVE VITALS, ON YOUR DASHBOARD See heart rate, breathing, and blood oxygen as the watch reads them. Open the app and the latest readings are waiting for you. CUSTOM ALERT LEVELS Set the limits that matter for the person you're watching over. Heart rate above 100? Below 50? Oxygen below 92%? Their watch fires an alert the moment any value crosses your threshold — no waiting hours for the next summary. FALL DETECTION When the wearer's Apple Watch detects a fall, FallGuard immediately sends an urgent push notification with the time and GPS location to all caregivers. No checking email, no delays — an instant alert right on your iPhone. ONE PERSON, ONE CARD The redesigned dashboard shows a big card for each person you're watching over — their name, status, and last update at a glance. Tap a card for full details. SIMPLE SETUP Pick whether you're wearing the watch or someone else is, and the app shows you the right experience. Add a person with their family code and you're done — no jargon, no menus to dig through. WHO IT'S FOR Adult children watching over aging parents. Caregivers monitoring patients. Anyone who wants real-time visibility into a family member's health and safety, without waking up at night wondering if they're okay. PRIVACY Vitals data only flows to caregivers who joined with your family code. Apple Watch handles fall detection and emergency calling at the OS level — FallGuard never replaces that, only supplements it with family-side awareness. REQUIREMENTS • An Apple Watch with watchOS 10 or later for the wearer • An iPhone running iOS 17 or later for caregivers • HealthKit and Notifications permissions We'd love your feedback. Reach us at support@fallguard.me. A FULL DAY OF HEALTH, NOT JUST A MOMENT FallGuard records vitals throughout the day and keeps a history, so you can see trends over time — not just a single stale reading. Compare this week to last to catch changes early. KNOW THE WATCH IS WORKING See at a glance whether the watch is worn, off, or charging, plus its battery and your loved one's phone battery — so you always know whether "no update" means all is well or the watch just needs putting on.
