Frequently asked
How does CardioAI measure my heart rate?
CardioAI uses your iPhone's rear camera and LED flash to detect tiny colour changes in your fingertip caused by blood flow — a technique called photoplethysmography (PPG). Simply cover the camera lens with your fingertip and hold still for a few seconds.
Is CardioAI a medical device?
CardioAI is designed for general wellness purposes and is not a certified medical device. It should not be used to diagnose, treat, or monitor any medical condition. Always consult a qualified healthcare professional for medical advice.
Why are my readings inconsistent?
Make sure your finger fully covers the camera lens without pressing too hard or too lightly. Good ambient lighting and keeping your hand steady will improve accuracy. Readings can vary if your finger moves during measurement.
Does CardioAI access the internet or my personal data?
No. All measurements and history are stored locally on your device. CardioAI does not require an account and does not transmit any health data to external servers.
How do I cancel my subscription?
Open the Settings app on your iPhone, tap your Apple ID at the top, then go to Subscriptions and find CardioAI. You can manage or cancel your subscription there. Apple handles all billing on our behalf.
Something isn't working — what should I include in my report?
Please include your iOS version, iPhone model, a short description of what happened, and a screenshot if possible. The more detail you share, the faster we can help.
