Cardiomic

🩺 Turn your phone into a simple heart sound observation tool.

❤️ Cardiomic is a heart sound recorder and heartbeat recorder that lets you capture heart sounds with your smartphone microphone, see the captured signal as a live waveform, and listen back to your own recordings over time.

📱 Use it in a quiet place, place the phone gently on your chest, and record a short session. When heart sounds are captured clearly, you can watch the phonocardiography-style waveform, review estimated BPM, and replay the recording after the session.

📈 Cardiomic is not just a heart rate number. It supports personal heart sound observation, heartbeat tracking, and heart rhythm tracking by helping you review the signal behind the beat: the sound, the rhythm, RR intervals, HRV metrics, coherence, and how your recordings may change across different moments.

💎 Premium:

Cardiomic Premium gives access to more than 7 saved measurements in your history, so you can keep reviewing older sessions over time.

🫁 For best results:

1. 🧘 Sit or lie down in a quiet room.
2. 📱 Place the phone gently and steadily on your chest.
3. ⏱️ Record for 30 to 60 seconds.
4. 📈 Try small position adjustments until the waveform becomes clearer.
5. 🎧 Use headphones when listening back, because the sound can be low.
6. 🔄 Repeat sessions in similar conditions to compare recordings over time.

🧠 Cardiomic is inspired by phonocardiography, the study of heart sounds, but it is designed for personal heart sound tracking and rhythm metric review. Your recordings are processed on your device.
