HRV: Heart Rate Cardio Monitor is a lightweight and intuitive app that allows you to measure your heart rate using your iPhone's camera and flash. With just a simple touch of your finger on the back camera and flashlight, you can instantly see your heart beating live.

The app provides all the necessary pulse information, including your current heart rate, HR waveform graph, estimated time passed, and camera signal quality. The camera signal quality indicator turns fully red when your finger is placed properly, ensuring accurate readings.

One of the standout features of HRV is its user-friendly interface, free from disruptive popups or persistent offers to upgrade. There are no mandatory registrations or subscriptions, only a one-time premium purchase option for those who want additional features.

In addition to its heart rate tracking capabilities, HRV offers dark and light themes, an indefinite scanning mode for continuous pulse tracking, and reminders to help you stay on top of your heart health. The app also provides advanced metrics such as RR, SDNN, RMSSD, NN50, PNN50, LF, and HF.

It's important to note that the pulse rate data and HR waveforms displayed by the application are for reference purposes only and not intended for medical use. For healthcare purposes, it is recommended to use medical-grade hardware.
