iPhone – An App that measures your heart rate with the iPhone’s camera and battery
The free Heart Fitness app from Senscare measures your heart rate, by using your iPhone’s camera and a light source to watch blood pulse through your finger. Just follow the directions, and it’s pretty accurate! It shows your beats per minute, plus the pulsing heart rate graph we all know and love from medical dramas. It even charts your resting heart rate over time, as a measure of overall fitness. Heart Fitness works best with the iPhone 4, since its camera flash lights your finger up nicely, but it can work with the iPod Touch or iPhone 3GS if you hold it up to a bright light. Got an Android device? Try Instant Heart Rate on the Android Market, instead! Both apps are free to download.
