Does Apple Watch Call 911 If Your Heart Stops?
No. Apple Watch does not automatically call 911 just because your heart stops or no pulse is detected.
Apple Watch has Emergency SOS and Fall Detection, but those features have specific conditions and generally require user action or a detected fall.
RscMe does not call 911 either. RscMe sends SMS alerts to selected contacts when configured heart-rate limits are crossed and credits are available.
Apple Watch built-in alerts vs RscMe
Apple Watch built-in alerts notify only you. RscMe sends SMS to up to 5 trusted contacts with your name, current heart rate, and a GPS link.
Apple Watch alone
- Heart-rate alerts go only to you
- Emergency SOS typically requires user action
- Fall Detection can call emergency services after a hard fall
- Uses Apple's fixed thresholds
With RscMe
- SMS to your selected contacts (up to 5)
- Message includes name, heart rate, and GPS location
- Contacts receive normal SMS, no app needed
- Custom high/low limits (tachycardia/bradycardia)
Apple Watch and iPhone requirements
Apple Watch is required for monitoring. In normal use, your iPhone should be nearby for SMS sending.
Monitoring modes and Battery Saver
- Normal monitoring: approximately every 5 seconds.
- Battery Saver mode: when Apple Watch Low Power Mode is enabled in Settings → Workout → Low Power Mode, checks are approximately once per minute.
- Both modes can trigger alerts when thresholds are crossed.
Alert delivery is not guaranteed in all situations.
How SMS alerts work in practice
When alert conditions are met, RscMe sends SMS alerts with your name, current heart rate, and a location link so your trusted contacts can react quickly.
Alert Credits pricing: $2.99 for 20 credits and $6.99 for 50 credits. Credits never expire. Each alert uses 1 credit per contact and alerts are sent only if credits are available.
