Stop guessing if you are stressed or why you feel "off". Your body is leaving patterns, and PulseCheck translates them for you in just 60 seconds.

Using only your phone’s camera, PulseCheck measures your heart rate and heart rate variability (HRV) to instantly reveal whether your nervous system is in a stressed, strained, or recovered state.

We built PulseCheck because we were tired of health apps giving inaccurate readings without warning. You deserve to understand your own body, which is why PulseCheck is private, honest about accuracy, and free to start.

Why PulseCheck is Different:

The Confidence Level (Our Honest Moat)
Most heart rate apps lie to you when the lighting is bad or your finger slips. We don't. PulseCheck is the only app that shows a real-time confidence level for every single reading. If the measurement isn't accurate, we tell you not to trust it.

Free to Start
Your first readings are free, with no account and no card. Going deeper with trends, programs, and your personal baseline is part of PulseCheck Premium.

Privacy First, Always
We do not want your data. Your measurements, logs, and health history stay strictly on your device. No accounts required. No backend cloud storage. You are in total control.

What You Can Measure & Track:
• Heart Rate (BPM): Get an accurate pulse reading in seconds.
• Heart Rate Variability (HRV): The scientifically proven marker backed by 20,000+ studies that reveals the true state of your nervous system.
• Stress & Recovery State: Instantly see if your body has the energy to push hard today or if you need to rest and recover.
• Blood Pressure & Vitals Log: Keep a reliable journal of your blood pressure and oxygen saturation to share with your doctor.
• Lifestyle Impact: See exactly how your sleep, workouts, caffeine, and daily habits affect your heart health trends over time.

Who is PulseCheck for?
• Anyone experiencing unexplained fatigue, anxiety, or physical stress who needs data to validate how they feel.
• People managing chronic conditions who need a reliable, on-demand tool to track their vitals and share reports with their doctor.
• Athletes and biohackers looking to optimise their training by measuring daily recovery scores.
• Anyone who wants the insights of a $300 smartwatch without having to wear one.
• Anyone who wants to check how sleep, alcohol, caffeine and travel affect their heart state, body battery and recovery states.


Your heart knows exactly what is going on with your body. It is time you started listening to it.

Important Note: PulseCheck measures heart rate and HRV using your phone’s camera. It is not a medical device and does not diagnose, treat, or prevent medical conditions. Always consult a healthcare professional if you have health concerns.

Below are the few users'. testimonials:
1. I didn't know I could check my heart rate with my iPhone! Now I check my heart and HRV after sleep, before sleep, and pre and post my training to see how I should plan and whether I am improving!
2. I was honestly a bit sceptical that an app could measure my heart rate and HRV just using the phone camera, but I tested it against my chest strap monitor, and the results were almost identical! It’s incredibly convenient when I don't want to wear my smartwatch. The daily energy and stress scores are a fantastic bonus.
