Mijn HartslagNu is a free Android app developed by Stan - Standby to help that could potentially save someone's life. With 40 people outside the hospital in the Netherlands experiencing cardiac arrest each day, every minute counts. This app is designed to alert you when someone in your vicinity has a cardiac arrest, allowing you to provide life-saving help.

Mijn HartslagNu works by sending an alarm notification to you based on your home and work address or GPS location if you give specific permission. The 100 nearest civilian emergency responders are alerted within a 2 km radius, along with any nearby AEDs. With enough volunteers, the remaining responders will receive a notification to avoid overcrowding the scene.

This app also allows you to view your previous alarm notifications and questionnaires, locate nearby AEDs, and use the HSN passport for identification on the scene.
