Instant Heart Rate: HR Monitor
This text is promoting the Instant Heart Rate app, which is described as the most accurate and easy-to-use heart rate app. The app claims to provide users with their heart rate in less than 10 seconds and also allows them to check their stress levels, see trends, and gain insights. The app has been featured in Apple's TV ad and has received media coverage from various sources. It is rated as the number one heart rate app in multiple countries and is trusted by cardiologists at Stanford for use in clinical trials. The app works by placing the tip of the index finger on the iPhone's camera, which detects a color change in the finger each time the heart beats. The app offers various features including heart rate measurement, heart rate activity zone calculator, pulse waveform graphs, real-time photoplethysmogram graph, and more. There is an option to upgrade to a premium version for additional features and support. The app is not intended for medical use but rather for recreational and fitness purposes.
