Customer Reviews

This app is great! Highly Recommended.

I'm looking forward to trying the new features in this update. I've been a big fan of this app for over two years. December, 2014.

I continue to use this app on a regular basis to check my heart rate. (For some reason I've always found it a problem to consistently feel my own pulse.)
Also, I've found the app very useful for checking my heart's rhythm. I use the app routinely to confirm that I'm in normal rhythm, when I don't have easy access to a stethoscope.
In addition to the visual and auditory enunciation of the heartbeat, the app also has a useful graphical output. Maybe not accurate enough for checking one's QT interval, but otherwise informative.

Great app! The visual and audio enunciation of the heart beat makes the app a good tool for checking one's heart rhythm. I'm amazed at how well the app functions. Recommend it highly. August, 2013

Works well and does exactly as advertised. Well worth the optional 99 cents payment. I gladly paid it to support the app. Important to read the instructions and understand how the app works. Instructions are clear and simple.

I continue to be amazed at the accuracy of the app. I highly recommend it.

Have been using this powerful app daily for several months. Last update added some nice improvements. The additional features of the optional 99 cents version are an amazing value. - April, 2013

Clever idea to use the camera. Great job!

I have been using this app for more than two years now and have been able to trend my heart rate over those years. By doing so it keeps a good check on my health that when the rate goes up I know that I'm stressed.
It also detected an issue that I've been having when BradyCardia episodes rise up. And I am able to show that information to my doctor.
Though my doctor doesn't believe in this tool, she cannot deny the trending of the results… So, she does consider it, nonetheless.
This is one of those apps that is definitely a must need for me since I use it at least three times a week.
However, time does change things and when the Apple Watch comes out with its extensive health related functionalities, I believe it will replace this app since I will be getting the iPhone 6. I currently have an iPhone 5S. Sorry, but thanks… It was a great ride.

Works -But Paid Version Is NOT Ad Free :(

This app does a good job of measuring heart rate. It also allows you to tag your results with built-in or custom tags. Sounds great, right? Two problems, though:

1. There is a long-standing issue with the tags occasionally disappearing. Sometimes it goes away, only to return. Disappointing.

2. The bigger and more annoying issue is that I upgraded from the FREE to the PAID app only to find that it is still filled with advertising! It's not ads for third-party apps but for the developer's own products. That is just str8-up rude!
Even more annoying is that the advertisements pop up RIGHT AFTER you measure your heart rate and you can't tag without dismissing the full-screen ad! I just finished working out, I may be working at an Xtreme or Max heart-rate, and the developer wants you to check out their other products?!?!?!? This is unacceptable for a PAID app.
Sad, but true.

Remove this annoyance and it's an easy four stars, but the developers are clearly just cashing in without concern for user experience even after they have your money.
