Cardiom estimates pulse from your iPhone cameras: Finger PPG through the fingertip, or Face rPPG by scanning your face. Guided, short, and only saved when the signal quality is good.
Finger PPG: rest a fingertip gently over the rear camera and flash. Face rPPG: hold the phone so your face is in frame — no contact needed — and Cardiom reads subtle skin-colour changes from the pulse.
Cardiom prepares the right camera, shows placement cues and waits for a clean signal. Progress starts only when the reading looks usable.
Keep still in steady light. Sessions never run longer than 30 seconds. Soft light in front of you helps Face rPPG; a relaxed fingertip helps Finger PPG.
Cardiom labels which method you used, so Finger and Face trends stay comparable. Add context, build your baseline and return over days and weeks.

Visit support ↗No. Cardiom is designed around the cameras already built into your iPhone. You can also add readings from devices you use separately, such as a blood-pressure cuff or pulse oximeter.
Those values are entered manually from a dedicated device or another trusted source. Cardiom does not claim to measure them through the camera.
Finger PPG is a contact check-in: you place a fingertip over the rear camera and flash so Cardiom can read light changes from blood flow. Face rPPG is contactless — the front camera scans your face and detects tiny colour changes linked to your pulse. Cardiom labels each method and lets you compare Finger and Face trends separately.
Yes. Choose Face rPPG for a contactless reading. Keep your face in the guide, use even light from in front of you, and stay still. Soft daylight or a lamp in front of your face usually works better than strong light from behind.
HRV details appear only when a session contains a suitable beat-to-beat signal. The 7-day Stress Index unlocks after check-ins on seven distinct days so it can reflect a longer pattern.
