Instant Heart Rate - Heart Rate Monitor by Azumio Free

By Azumio Inc.

Open iTunes to buy and download apps.


The best Health & Fitness app on Mobile Premier Awards 2011 according to the jury of industry experts and as seen on Dr. OZ show.

See every heart beat on the monitor, just like in ER rooms. Measure your heart rate instantly!

Instant Heart Rate uses your iPhone's camera to detect the pulse from your fingertip - leveraging similar technique as used in pulse oximeters.

Place the tip of your index finger on the iPhone’s camera, and in a couple of seconds your pulse will be shown. Instant Heart Rate will beep with your pulse. A real-time chart will show you every heart beat.

- Heart pulse measurement
- Real-time PPG graph
- Continuos or Auto-Stop mode
- Heart Rate Zones
- Pulse waveform graphs
- One week data storage and tags
- Export data for registered users
- Sharing to Twitter and Facebook
- StandUP test for fatigue and fitness testing as an in-app purchase.

NOTE: Works best on iPhone 4/4S/5 because it has flash. On iPhone 3GS and iPod touch it has to be used in good lighting.

NOTE: Make sure that your fingertip completely covers the camera lens. Press gently, since pressing too hard reduces blood flow in your finger and it's harder to get a result. Make sure that your fingers are not cold. This app is for recreational and fitness use only!

From our heart to yours,

Like it, and suggestions how to use

Just went to the doctors, who measured me at 93BPM. This app measured me at 96, but measurements varied by three in either direction. What I did was re-measure myself, but did the following:

* I was completely at rest.
* I placed my finger on the camera lens, at a 45 degree angle.

* and most importantly, I held my finger steady using my thumb and forefinger - so the thumb was on the front of the iPhone. While holding it steady, but did not press down too hard.

The results were a consistent 92 or 93 BPM.

If you hold your finger steady with thumb and forefinger, and relax while tested, I believe the app is really super accurate.


Works very well and matched my blood pressure machine within 2 beats. Make sure you use light pressure with your finger. At first I could not get a reading because I was using too much pressure . I've had this app for some time now . Since I have a bad heart, I use it all the time. This is one of my most important app's.
I am not sure why this app is asking me to submit a second review? My review would be the same as above. I have a bad heart so I find this app very handy indeed since I almost always carry my phone with me. Plus it reminds me to check my heart rate!
This is a great app! Very cool indeed!

Monitor HR changes due to Anxiety

I like this app as a simple tool to help me visually monitor my anxiety. Soon as I feel my heart beating like crazy I use the app, then I can do some focused breathing & check my heart rate when I feel more calm.

I realized that I have a pretty slow resting heart rate so when I feel anxious/stressed out it doesn't get too high. Made me realize I need to be looking at my heart rate according to my daily "normal." So, tracking daily resting HR is good to do initially to get a sense of own HR patterns :) I got a new phone so hvg to start tracking from scratch again.
