## What is CardioX?

Every heartbeat matters in decoding your cardiovascular health vitals. With CardioX AI-powered mobile app you can track your Blood Pressure (AI BP), Heart Rate, and all major HRV parameters. CardioX mobile app was built around a powerful neural network, which can estimate AI BP based on a short ECG interval. 
Our neural network is a combination of an enormous database of real clinical records and machine learning algorithms that allow us to analyze users’ data and use it to maximize the accuracy of the estimated metrics.
CardioX mobile app works by interpreting an ECG graph recorded by a wearable device. Currently, we support all major smartwatch brands as well as wearable ECG monitors.

*If your device is not currently supported or you’re getting an error when importing your ECG file, you may email us a PDF file with an ECG graph, recorded by your wearable device, so we could get it programmed ASAP.


Some of the main features of CardioX:

-Estimation of AI BP (AI estimated blood pressure).
-Levels of productivity, energy, and stress based on the Heart Rate Variability analysis.
-All major Heart Rate Variability metrics.
-Journal for keeping health records organized. Each reading is recorded in the journal with an option to add personal notes.
-Reports to show trends in your AI BP, Heart Rate, Productivity, Energy, and Stress.
-Export your current readings or share them with your doctor in a convenient PDF format.


HowCardioX works:
* This is the beta version. Future updates will be available with new features and improved automation.  
Install CardioX app
Have your fitness tracker or ECG monitor ready and take your ECG reading.
Open CardioX AI BPM app on your smartphone and follow the steps to create your personal account. Make sure to provide accurate information, since it will be used to provide the most precise AI BP readings.
Import PDF file with the ECG graph generated by your wearable device.
You will be prompted to calibrate the app by measuring your blood pressure using a traditional tonometer. Calibration is optional but recommended in order to provide the most accurate AI BP reading.
Get your estimated AI BP, HR, and HRV readings. 

CardioX mobile app is an invaluable tool to monitor your AI BP. Detecting early signs of hypertension can drastically improve your future cardiovascular health and motivate you to lead a healthier lifestyle.

### 2/5 — Was working well

*2024-11-24*

Since updating to IOS 16.3.1 this app crashes with a lot of red writing saying something about certificates. It was a good app to be able to see my ECG history.
It is happening again. Please look into it as I find this app very useful.
Do you read your feedback? Since June this year I have not been able to import ECG readings from the health app. 
You need to either sort this app out or remove it before I report it to Apple.

This is very cool. You should get this because it can measure your heart rate very quickly and is advanced.

### 1/5 — Non funziona più!

*2022-07-19, version 1.2*

Cercando di aprirla da una serie di errori e non si avvia… :-( (lug.2022)

### 3/5 — Misuratore della pressione

*2022-01-16, version 1.1*

Non ho potuto ancora calibrarla con un strumento idoneo , però devo dire che il dato sembra verosimile.
Sarebbe carino se avesse l’app per l’Apple Watch.
Alla fine è anche gratuita … aiutiamoli !
