Cadyne is a cardiac-coherence breathing companion. Breathe at a calm, steady pace, follow a smooth on-screen guide, and keep a simple record of your practice - all in one fast, private app with no account required. THE 365 METHOD The classic cardiac-coherence rhythm: 3 sessions a day, 6 breaths a minute, for about 5 minutes. Cadyne paces every inhale and exhale with a soft visual guide and optional audio cues, so you can keep your eyes closed and just follow the sound. GUIDED BREATHING PATTERNS Cardiac coherence, box breathing, 4-7-8, and resonance breathing are built in. Pick a pattern, set the length, and start - the pacing engine keeps perfect time so you never have to watch a clock. SCREEN-OFF AUDIO Audio guidance continues when your screen is off, so a session keeps pacing in your pocket or on the nightstand. Choose calm cue tones or quiet soundscapes. YOUR HRV TREND Cadyne reads your heart rate variability from Apple Health and shows your own trend next to your practice days - a read-only view of your data, not a measurement or a diagnosis. PRACTICE LOG AND STREAKS Every completed session is logged. See your days at a glance, build a streak, and watch your practice add up over weeks. PROTOCOL EDITOR Build your own patterns. Set inhale, hold, exhale, and pause to the second, name it, and save it next to the presets. APPLE HEALTH Completed sessions can be saved to Apple Health as Mindful Minutes, so your breathing practice lives with the rest of your wellbeing data. PRIVATE BY DESIGN There is no account and no server. Your practice log stays on your device, and Cadyne uses no analytics or tracking SDKs. NOT MEDICAL ADVICE Cadyne is a breathing-practice timer and a personal record. It does not provide medical advice, diagnosis, or treatment, and it is not a substitute for a qualified professional. Always follow the guidance of a licensed professional. Find your calm, one breath at a time, with Cadyne.
