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. Hold it in your palm, rest it on your chest, or slip it into your pocket, and let the steady pulse take over. Close your eyes, and simply feel it. FREE • Adjustable heartbeat (40–70 BPM) and vibration strength • A real heartbeat sound in perfect sync with the pulse — nothing to calibrate, they simply play together • The sound adapts: a fuller sample through headphones, a cleaner one through the speaker — it switches by itself when you plug in • Pocket mode: black screen, minimum brightness — put it in your pocket or on the mattress • Sleep mode: the heartbeat sound keeps playing with the screen locked, all night • Timer from 1 to 60 minutes, or unlimited • Dark and light themes, 14 languages PRO — one-time purchase, NO subscription • Programs: calm heart, deep sleep, power nap, focus — one tap and everything is set • Custom wind-down: you choose the starting tempo, the target and how long the descent takes • Haptic-guided breathing: 4-7-8, box and coherent — followable with your eyes closed, by touch alone • Personalised tempo: suggests a starting rhythm from your Apple Watch resting heart rate • Save your own setups by name and recall them with one tap • All future Pro features, forever GOOD TO KNOW The vibration works while the app is open — that's exactly why pocket mode exists: with a black screen, your phone can stay in your pocket or beside your pillow. If you want it to continue with the screen locked, turn on sleep mode and the heartbeat sound carries on. iPad has no Taptic Engine, so there the heartbeat plays as sound only — vibration needs an iPhone.

Your resting heart rate is read from the Health app only if you allow it — and that data never leaves your phone. CardiCalm is a wellness app for relaxation.
