## What is Heart Rate Display?

Detect and display your heart rate using an iPhone or iPod/Touch.

Notice: This app demonstrates the detection of one's heartbeat using an accelerometer. Although under the right circumstances it can be quite accurate we do not recommend using Heart Rate Display for critical medical applications.

How to Use:

Sit or stand. Hold the device in one hand. Rest that arm on the edge of a stable surface like a table midway between your hand and elbow. Start up app. Do not move. It takes 5-10 seconds for the device to auto-adjust the signal from the accelerometer (this is the blue line in the top graph). The detection algorithm takes about 10-20 seconds to find your heart beat (middle graph). The red line is your detected heart rate (40-240 beats per minute). The bottom graph plots your heart rate over a 5 minute period.

App automatically captures a screen shot every 30 seconds. Tap upper left button to send email with latest screen shot attached.

### 1/5 — Horrible!

*2013-02-22, version 1.0*

Don't waste your money. This app does not detect anything but shaking or movement of your arm. It had my heartrate between 40 and 200+ bpm. If I took my own pulse, it was 65-75 bpm. Please don't buy this. I wish there was a way to get a refund!

### 1/5 — Doesn't work. Based on shaking

*2012-04-25, version 1.0*

Doesn't work

### 5/5 — Fun app!

### 4/5 — Works!

*2012-02-04, version 1.0*

Cool app
