Ariadna for Android download

Why every minute counts

In out-of-hospital cardiac arrest, the chance of survival drops by roughly 10% for each passing minute without treatment. Rapid access to a defibrillator can be the difference between life and death, so locating one quickly is critical.

What the app does

Provides an interactive map of Automated External Defibrillators (AEDs) across Spain so you can find the closest device fast.
Lets users attach photos and precise GPS coordinates to AED entries, improving location accuracy.
Enables confirmation of existing entries submitted by other people to keep the database reliable.
Shows device locations in both public and private spaces, increasing the number of accessible AEDs listed.

How volunteers and the public help

Anyone — not only certified CPR responders — can add AEDs to the registry, making it a true crowd-sourced resource.
Contributors can validate devices uploaded by others to improve data quality and trust.
The community model helps maintain an up-to-date inventory of defibrillators throughout the country.

Rewards and motivation

The app uses gamification to encourage participation: users earn symbolic badges for uploading or verifying AEDs.
Those badges build a personal record of contributions visible on your profile, recognizing active participants.

Origin and purpose

Ariadna was created through a collaboration between the Spanish Society of Cardiology (Sociedad Española de Cardiología) and the Red Cross (Cruz Roja). It is part of the SEC-Calidad initiative, a program focused on preventing, diagnosing, and improving treatment for cardiovascular disease while promoting better heart health in the general population.
