Apple Watch
An extra layer of awareness for your heart during rest and sleep.
Cardiac Alarm is a standalone Apple Watch app engineered to provide an additional layer of monitoring for individuals tracking specific heart rate trends. It is designed to notify family members when a critical pulse reading is detected, offering added support for you and your loved ones during your quietest hours.
How it works. When a monitoring session is active, the app tracks heart rate data via the Apple Watch sensors. If the system detects a heart rate below the fixed 33 BPM threshold or a loss of signal, it triggers a high-volume siren. This alert is specifically designed to be loud enough to notify those in your immediate surroundings so that support can be initiated if necessary.
Who is it for. Cardiac Alarm is a tool for individuals interested in maintaining a high level of awareness regarding their heart rate trends. While it is a wellness tool, it provides a valuable supportive layer for those who wish to stay informed about their cardiac data during rest or sleep.
IMPORTANT: Best-Effort Tool & Limitations. Cardiac Alarm is a best-effort tool. Due to inherent technical limitations, software errors, or hardware malfunctions, the app does not guarantee the detection of every pulse drop or cardiac event. Monitoring frequency is strictly dependent on Apple Watch sensor availability and hardware performance. The app requires an active monitoring session and firm skin contact (proper device fit) to function. It cannot alert to events that occur between sensor readings or if the system is interrupted by OS constraints or battery depletion.
Please Note: Cardiac Alarm is a monitoring and alerting aid only; it does not provide medical treatment, diagnosis, or first aid instructions. It is not a life-saving device and should not be relied upon as the sole monitoring system in life-threatening situations.
MEDICAL DISCLAIMER: This app is intended for informational and monitoring purposes only. Cardiac Alarm is NOT a medical device and is not a substitute for professional medical advice, diagnosis, or treatment. The 33 BPM threshold is a fixed safety parameter and cannot be modified. Always consult your cardiologist regarding your health and treatment plan. In case of a medical emergency, contact your local emergency services immediately.
