Description by Precordior Oy (from Google Play)

Gain information about your heart health in just one minute with your phone.

CardioSignal application is a reliable and easy-to-use CE marked (Class IIb) medical device. The intended purpose of the application is to detect signs of atrial fibrillation in adults (aged 18 years and older).

Why use CardioSignal:

Atrial fibrillation is the most common heart rhythm disorder, and it may present without symptoms. With regular monitoring, it can be detected and treated early. When left untreated, atrial fibrillation can expose to e.g. stroke and heart failure.

How it works:

The app is easy to use: Lie down and relax. In the app, press the start button and place your phone in the center of your chest. The measurement takes 60 seconds, after which you will get the result shortly. If after a ‘Repeat the measurement’ result you get a ‘Signs of atrial fibrillation’ result, contact your doctor or care provider. Visit https://cardiosignal.com/support for more information.

Our patented technology utilizes smartphones' motion sensors to detect signs of atrial fibrillation, and is based on a decade of academic research and algorithm development. The accuracy of the CardioSignal app is 94% to detect signs of atrial fibrillation.

Please note that the atrial fibrillation measurement requires a 1 month, 3 month or 1 year subscription. Creating a user account is required. For more information, please visit https://www.cardiosignal.com.

Contraindications (= when the device should not be used)

This application is intended for individuals aged 18 years and older. Do not use it on those aged under 18 years. The heart rate of children and adolescents can be significantly affected by their breathing rate and a normal heart rhythm might look irregular.

Do not use the application for individuals who have a cardiac pacemaker. A powered-on phone held close to a cardiac pacemaker can create electromagnetic interference (EMI), which may alter the function of the pacemaker.

Comments on CardioSignal for Android

★★★★★ Kamal Jafarian · Jul 19, 2021

The idea of just using built-in sensors of a smartphone to detect atrial fibrillation is fantastic. Bravo! 👏👏

★★★★★ Ricardo Stephenson · Mar 30, 2023

Awesome app. A potential lifesaver. It converts your phone into a fine medical instrument that with the built sensors make it conducive to picking up afib irregularities. For a few quid a month, having this info makes it an invaluable kit for Joe public to use in monitoring heart irregularities. This app and having it is a no-brainer for me. An app that potentially could give me a warning ⚠️ of my heart health. Best app ever for me. Trust me, you won't regret purchasing it. I promise !!!

★☆☆☆☆ Johnathon Weare · Aug 27, 2023

Installed per recommendation of Omron connect app. That in itself wasn't clear enough for my liking. Ok, this app itself has no free trial, and the minimum subscription is £4 for a month which isn't upfront enough in my book. Best avoid until and unless all of this is completely transparent.

★☆☆☆☆ Matthew Welland · Jul 15, 2024

Signed up as recommended by Omron to use for free. It's asking for money, not impressed !

★☆☆☆☆ nige J P · Jun 22, 2025

What a disgusting way to get money out of you download the app and do the test then they won't show you the result until you pay a subscription. Shame on you and shame on moron for recommending it
