Instant Pulse measures your heart rate using the build-in wide angle camera of your iPhone, iPad or Mac.

From the moment you place your finger calmly on the camera and stand still the app needs only 8 seconds to measure your heart rate and save the result.

If you are using an iPad or Mac with no camera flash, you need to take your measurements in a well lit environment - under the direct sunlight or close to another light source.

DISCLAIMER

Instant Pulse measures your heart rate accurately but it is not an actual medical equipment.

Normal resting heart rate for adults ranges from 60 to 100 beats per minute.

Consult your doctor if your resting heart rate is consistently above 100 beats a minute (tachycardia) or if you're not a trained athlete and your resting heart rate is below 60 beats a minute (bradycardia) — especially if you have other signs or symptoms, such as fainting, dizziness or shortness of breath.
