About this app
Auto-SOS via SMS + call (with GPS location) to your chosen emergency contact — even offline.
Not a government alert app: when you can’t call for help, SafeGuard notifies your own contact.
Note: Heart-Rate Guard sends immediately (no countdown); other modes include a 60-second grace timer.
SafeGuard is a safety app built for emergencies. It helps anyone who may need assistance when they can’t call for it themselves, by automatically sending an alert message.
Latest update: Let your heartbeat speak — Heart-Rate Guard and SOS Flashlight are now available.
Key Features
Heart-Rate Guard (no countdown): Connect your heart-rate watch/band. When your heart rate stays abnormal for an extended period, the system automatically sends an SMS to your chosen emergency contact and dials that contact’s number.
One-Tap SOS: Press and hold for 3 seconds to send your prewritten help message (location text optional).
SOS Flashlight: One tap to activate a high-intensity SOS strobe (…—…) so you’re easier to spot.
Automatic Help: No user action needed. When abnormal conditions occur, the system automatically starts the help flow.
Emergency Notification: Automatically sends a location SMS to your chosen contact and can automatically place a call to that contact.
Crash Detection: Detects sudden stops and impact changes to automatically trigger the alert screen.
Inactivity Countdown: If the phone isn’t used beyond your custom duration, it automatically enters a protection countdown and issues a warning (60-second grace).
Wake on Lock Screen: Even in the background or with the screen locked, it can display a full-screen alarm above the lock screen.
User Customization: Customize protection durations and automatic alerts to contacts according to your environment.
How to Use
Four protection modes cover different scenarios, at home or on the go. If an abnormal event is triggered and the alert isn’t dismissed, the system will notify your emergency contact.
Heart-Rate Guard: Pair with your heart-rate watch/band → in the app’s “Heart-Rate/SOS” page, enter and save your emergency contact and help message → turn on heart-rate monitoring. Monitoring continues even when the screen is locked.
One-Tap SOS: When you need immediate help, press and hold for 3 seconds to send the help SMS (location text optional).
SOS Flashlight: In dark environments or when you need attention, turn on the SOS flashlight with one tap.
Existing protection modes:
• SafeGuard: For static detection — if there’s no phone use beyond your custom time, it enters countdown and sends alerts automatically.
• CrashGuard: For dynamic situations — e.g., after an impact with no movement, it starts the alarm and sends alerts automatically.
• DateGuard: Low-distraction operation (keeps necessary notifications) and automatically sends an alert at your set time (low profile).
After an alert is triggered, an alarm sound plays and a pop-up appears. Tap “I’m OK” to dismiss.
Suggested Use Cases
• Living alone, working alone, late-night commute/run
• Driving, riding, public transit, outdoor sports
• Any moment you feel unsafe or need help even when your hands can’t move
Free Trial
