★★★★★ "Fake waveform. I also have the Kardia 6L EKG device. The waveform is totally fake. At least the CARDIIO app does not pretend to be EKG. That app shows actual blood flow variations more like a sine wave but real" - Gary W Martin

★★★★★ "Major flaw. It show the heart rate ok, but it will only save it if the heart rate is regular and normal rate. I want to show my doctor when rate was irregular and jumped from fast to slow. It is worthless at this point." - PippinSays

Fake waveform
I also have the Kardia 6L EKG device.
The waveform is totally fake.

Not a real ekg
This app is bound to give people anxiety. Folks this is not a real ekg and can not tell you anything about your rhythm. Get a Kardia or an Apple Watch if you want an ekg.

If you have heart issues and/or need to check your heart in public, this is not the app for you.

Totally inaccurate & unreliable
I have been using this for a couple of weeks. I compared the readings with one of those finger pulse/oxi meters that doctors are now using. The heart rate measurements were not the same. Sometimes very different. I also compared with a BP cuff. Same inaccuracies. The graph of the heart beats is also totally off. It appears to be fake. I have tried contacting the vendor and they have not responded.
STAY AWAY FROM THIS

Much artifact gave erroneous results when checked against wrist pulse.
I’m sorry
I’m sorry to give it such a bad review, but I tried 23-30 times both front and back camera without getting a successful reading.
Works great for normal rhythm
The app records heart rate if everything is OK. I have tachycardia. During an episode, it fails to work, and gives error message every time.
Does not work!
Waste of money does not work correctly.
Misleading!
I had the older version of this app from the same developer and a few days ago there was a message asking me to upgrade to the new version for free. I did and was charged $1.99!
Worthless, ineffective piece of junk.
Even if I sit PERFECTLY still like it wants me to, this fails to capture a pulse or is wildly inaccurate: it shows 54 BMP with an irregular heartbeat right AFTER I stop exercising . It's only two bucks, but get a small latte instead.
No está actualizada
La aplicación no está actualizada, ni funciona bien con los dispositivos de doble y triple camara.
Too short

Misleading... fake waveforms
Accurate to take pulse, but the waveforms are fake. I think it was misleading to make it look like you are getting more data back than you are. Want my money back.
