No Bluetooth Connection Option within Kardia App on iPhone

Bluetooth is on, in Settings on my iPhone 14 but the device keeps saying to turn Bluetooth on when I’m trying to “find device”. The Kardia app itself doesn’t have the Bluetooth icon within “Allow Kardia to Access” it only shows access to Siri, Search, Notifications and Cellular Data….there’s no Bluetooth to turn on here. Which is why no device is found when I try to find device. Why isn’t the Bluetooth button included in the actual app to turn Bluetooth on? My phone is operating on 26.6.1. Help!

Amazing helpful technology

This is a must device if you have AFIB. Easy to operate and very accurate.

I love getting the immediate feedback: afib or no

I wish you still load the model that you could attach to my phone. now it’s another device I have to carry & hopefully not lose.

The APP needs to suppress the first ten seconds of recording while the vectors stabilize

Time to revise the app!

Great product

I’m not a doctor. The only thing I have in common with my cardiologist is a heartbeat. But he recommended this device and I trusted him. And it does exactly what he said it would. This device helps me retain the peace of mind I need to not feel anxious about my heart.

FAQ

What does the Kardia app do?

The Kardia app works with specific FDA-cleared Kardia personal EKG devices to record medical-grade EKGs. It provides instant analysis for common arrhythmias like atrial fibrillation, bradycardia, and tachycardia. The app also allows you to manage your heart care from home by sharing your heart data with your doctor and tracking your health history.

What are the key features of the Kardia app?

Key features include the ability to capture medical-grade EKGs anytime, anywhere without wires or gels, immediate analysis of your EKG results, and the option to share recordings with your physician or for a clinician review. It also helps you track your heart health data and integrates with Apple Health for a combined view of your metrics.

How much does the Kardia app cost?

The Kardia app itself is free to download and use. However, it requires the purchase of compatible Kardia hardware, such as the KardiaMobile, KardiaMobile 6L, or KardiaBand device, to record EKGs. Additional clinician review services may incur separate costs.

What hardware is needed to use the Kardia app?

To record an EKG with the Kardia app, you need specific hardware: either the KardiaMobile, KardiaMobile 6L, or KardiaBand personal EKG device. These devices are sold separately and are necessary for the app to function for EKG recording.

Who is the Kardia app for?

This app is designed for individuals who want to proactively manage their heart health from home. It is particularly useful for those who need to monitor for common arrhythmias, have been advised by their doctor to track their heart rhythm, or want to easily share EKG data with their healthcare provider for remote assessment.
