FAQ
1. Does the app require an iPhone to be nearby to trigger the alarm?
No. The siren sounds directly from your Apple Watch, even if your iPhone is not nearby or is turned off. Alerting your Guards needs an internet connection.
2. Will the alarm sound if my watch is on Silent or Do Not Disturb mode?
Yes. Once you allow Critical Alerts during setup, the alarm sounds at full volume through Silent Mode, Do Not Disturb and Focus, on your watch and on your Guards' iPhones.
3. What triggers the alarm?
The alarm sounds when your heart rate falls below the low threshold you set or, if you switched it on, rises above your high threshold.
4. How can I be sure the alarm is working?
The watch app includes a built-in Test button. You can also send your Guards a test alert at any time. We recommend doing this once a month, and the app will remind you.
5. What is a Guard and how do I add one?
A Guard is a person whose iPhone sounds an alarm when yours goes off. You can add up to three. Create a connection code in the app and send it to your Guard. They install Cardiac Alarm, choose "I'm a Guard" and enter the code.
6. Does a Guard have to pay or own an Apple Watch?
No. Being a Guard is free and only needs an iPhone.
7. How do I cancel my subscription?
On your iPhone, open Settings, tap your name, then Subscriptions, and choose Cardiac Alarm.
8. Is Cardiac Alarm a medical device?
No. Cardiac Alarm is a monitoring and alerting tool for informational purposes only. It is not a medical device and does not replace professional medical advice, diagnosis or clinical monitoring. Always consult a physician about medical concerns.
