Customer Ratings & Reviews

Hi There, A subscription is not required to use the KardiaMobile with the Kardia app. Basic users who opt to not upgrade to KardiaCare still have the ability to detect and monitor basic arrhythmias using the included features in the Kardia App. KardiaCare is designed to help you get the most out of your Kardia device and provide you with deeper, more personalized insights about your heart health, but is not required to use the KardiaMobile and Kardia app.


When you create a new account, AliveCor collects the following required information: name, email, date of birth, sex, smoking status, height, and weight. We use this information to ensure that only you have access to this account. Other information we collect when you create a new account are: activity level, medications and medical conditions. This information is good to have as a baseline to understand your current condition. This information is not required to access your account. If you are a Premium subscriber, we may collect other information you may input into Kardia, such as EKG recordings, blood pressure, resting heart rate and activity levels. If you are a connected patient to your physician, all of this information will be seen in your doctor’s Kardia Pro account for identification and to help your doctor manage your treatment.

AliveCor does not resell any data we receive. AliveCor may use de-identified EKG recordings for future clinical research and feature improvements. All personal information is removed from a user’s EKG and stored on our secure and encrypted servers.

Thank you for your feedback. We apologize for any confusion during the setup process. While AliveCor offers optional KardiaCare membership plans for enhanced features and services, please be assured that the basic functions of KardiaMobile do not require a subscription. We are here to support you and provide clarity on how our products can be used effectively without additional costs. If you have further questions or need assistance, please contact us at Support@AliveCor.com or call 855-338-8800. We’re committed to helping you make the most of your device in a way that suits your needs.

Dear Shan, Thank you for sharing your concerns about the AliveCor KardiaMobile device. We apologize if there was any confusion or dissatisfaction regarding our product and its subscription services.

We would like to clarify that a monthly KardiaCare subscription is not mandatory to use the KardiaMobile device. Without a subscription, you can still record EKGs, store them on your device, and manually share them with your healthcare provider. The KardiaCare subscription is an optional service that provides additional benefits, such as unlimited cloud storage, automatic report sharing with your healthcare provider, and access to our Clinician Review Services.

We understand that every user has different needs and preferences, which is why we offer a range of options to suit your requirements. We apologize if this was not clear from the outset, and we appreciate your feedback.

As for additional gadgets, the KardiaMobile device is designed to function effectively on its own. However, we do offer accessories and other devices that can enhance the user experience, but these are optional and not necessary for the core functionality of the KardiaMobile device.

We are sorry to hear that you chose to return your device, but we respect your decision. If you have any further questions or concerns, or if you'd like to explore other options within our product range, please do not hesitate to reach out to our customer support team. We are here to help and ensure you have a satisfactory experience with our products and services.

Best regards,
AliveCor Customer Support Team
