SteadyPulse: Calm Heartbeat

SteadyPulse plays a warm, lifelike heartbeat at any pace you choose — a simple, steady sound to relax, focus, or drift off to. Unlike a plain metronome click, every beat is a real heartbeat tone: the familiar "lub-dub" rendered for each tempo so the rhythm always sounds natural. Set it slow for a calm, restful pulse, or quicker to match your breathing, your pace, or your mood. WHAT YOU CAN DO • Choose any pace from 50 to 140 BPM with a large dial and simple + / − buttons • Press play for a continuous, seamless heartbeat — no gaps, no clicks • Turn on Heart Rate Variability for a gentle, natural "breathing" drift around your chosen pace • Change the pace while it plays — SteadyPulse glides smoothly to the new rhythm and never cuts a beat short • Keep it playing in the background and with the screen locked WAYS PEOPLE USE IT • Winding down and falling asleep • Focus, study, and deep work • Calm, steady breathing and relaxation • A soft, familiar sound for soothing baby and adults alike • Pacing a slow walk or gentle movement • Pacing moderate to high intensity exercise WHY IT FEELS RIGHT A real heartbeat doesn't tick like a clock — it has a sound and a shape. Each beat is two soft sounds with a pause between them, and that pattern is what makes it feel calming and human rather than mechanical. SteadyPulse is built around that, with a built-in explainer that shows what you're actually hearing. I found myself using the metronome feature of Cadance in an effort to calm the anxiety caused by my safe, but really annoying, heart rhythm, with pretty good success. Cowbells and Congo drums got old, so I started researching how to create or capture healthy human heart sounds. I extracted the Metronome feature, improved it, and SteadyPulse was the happy result of that effort. Note: The HRV switch gives the beats a more natural, slightly jostled, feel and rhythm.
