Cardiio helps you measure your pulse (heart rate) using your phone camera, learn how the numbers relate to your general wellness, perform effective workouts to get in shape, and track your progress.
*** Featured on The Doctors (CBS), ABC News and more ***
MEASURE YOUR HEART RATE:
• Just hold your iPhone or iPad and simply cover the back camera with your finger to read your pulse
• See how your heart rate relates to your fitness and endurance
IMPROVE YOUR FITNESS:
• Built-in high-intensity circuit training exercises that only takes 7 minutes to complete
TRACK YOUR PERFORMANCE:
• Personal dashboard with history (daily, weekly and monthly)
• Save, edit, annotate, export your data (CSV)
HEALTH KIT INTEGRATION
• Save your heart rate measurements to the Apple Health app.
*Upgrade to PRO to enjoy the full features of the app!
Blood absorbs light. Every time your heart beats, the blood flow to your finger increases, causing more light to be absorbed. In between beats, less light is absorbed. By using your smartphone camera to capture tiny changes in reflected light from your finger, Cardiio can calculate your heart rate.
**IMPORTANT TIPS FOR BEST RESULTS
• ALWAYS hold your phone steady, keep still, and don’t talk during a measurement.
• Make sure your fingers are not cold.
• Cover the entire back camera lightly with your finger; Don't press too hard to avoid restricting blood flow to your finger.

A reasonable app
Generally good. The sensor part of the app does a reasonable job, when the circulation to my finger is good. Sometimes after a strenuous workout, or even during one measurements can get squirrelly. My BP tends towards low and so sometimes given the right circumstances it looks like I'm flat lining it.
The basic app is festooned with adds/add-ons of dubious benefit. Not quite as bad as some of the other count your heartbeat apps, but they're there.
Update 8/17 They've upgraded the measurement function so it reliably works on my iPhone 7. It's much better than doing a remote facial pulse determination. The add ons are still a bit gooey. I'm certain waveform will prove useful, but getting useful medical data from sporadic measurements is a bit weird.
Doesn’t work with iPhone 11 Pro Max
Beware - this app simply doesn’t work with the flagship Apple iPhone 11 Pro Max. The problem seems to be the three cameras built into the iPhone 11 Pro Max. I contacted the help desk who in turn simply replied that I should read the directions. Either the help desk people don’t realize their own app directions are no longer up to date for current versions of iPhone, or I hope I’m wrong but perhaps they simply don’t care about customers of this app any longer. The app directions only refer to iPhones with a single camera. If it was just experimenting with placing my finger over one of the three cameras of the iPhone 11 Pro Max, or some combination of cameras, I wouldn’t have had to see if the help desk could actually “help” a customer.
If you’re using most any version of iPhone less than the iPhone 11 Pro Max, this app is fantastic and works well.
I hope the developer decides to update this app for Apple’s flagship iPhone.
I also hope the help desk procedures get updated to provide actual help to customers.
Worked perfect forever...until now...
Always worked perfectly but I just got the new iPhone 11 Pro which has three cameras. The camera that the app uses is the bottom right camera but the flash it at the top left. Considering how the technology works this means that you cannot get a reading anymore as the light does not enter your finger.
The camera that is used needs to be swapped within the software of the app, else it’s not possible anymore to get a reading - it just gives a poor signal quality error message each time. :(
