Cardicalm

CardiCalm is a simple, tactile way to calm down: your phone's vibration becomes a slow, steady heartbeat that your body instinctively starts to follow. The calm rhythm helps you slow down, settle, and drift off to sleep more easily. Place your phone on your chest, in your palm, or in your pocket, and let the steady pulse take over. Perfect before sleep, in stressful moments, or whenever you just want to pause for a minute. FREE • Adjustable heartbeat (BPM) and vibration strength • A real heartbeat sound through the speaker, in sync with the vibration — the app measures your phone's audio latency and keeps correcting it, so the two stay together • Vibration calibration: it detects what kind of vibration motor your phone has and adapts the beat to it — and you can fine-tune it by hand • Timer: quick presets, or a slider precise to the minute, from 1 to 60 • Works reliably with the screen off and in the background • Dark and light themes, 14 languages PRO — one-time purchase, NO subscription • Biosync: measures your pulse with the camera, then gently guides the vibration down to a resting tempo • Custom wind-down: you choose the starting tempo, the target and how long the descent takes • Haptic-guided breathing modes: 4-7-8, box, and coherent breathing • One-tap goals — fall asleep, ease stress, quick calm — and save your own rhythms • All future Pro features, forever PRIVACY CardiCalm runs entirely on your device. No account, no data collection, no ads. The camera is used only to measure your pulse — the image is never saved and never leaves your phone. CardiCalm is a wellness app for relaxation. It is not a medical device and is not a substitute for professional medical advice or treatment.
