Cohera vs DreamKnock

Use your mind to align your heart. Cohera is a mind-driven heart-coherence trainer for Apple Watch. Bring your attention into the moment, pick a target rhythm, close your eyes, and guide your heart into sync while a living visualization drifts on screen. The whole point is that you can stop staring at numbers — the guidance is something you feel, not something you watch. When you're done, you get one honest score and a real sense of having slowed down. HOW IT WORKS Soft lub-dub haptic pulses pace your breath through your wrist — the gentle mechanism that helps your mind settle your heart into rhythm, tightly synced to the on-screen visual. Run a whole session with your eyes shut — no screen to stare at. ONE HONEST SCORE The Coherence Index (0 to 100) shows how closely your heart settled into your chosen rhythm, in plain language — Dispersed, Balanced, Aligned, Harmonic — instead of a wall of stats. FOUR RHYTHMS, ONE APP Choose your pace: Deep Rest, Calm Flow, Active Focus, or Walk & Talk. The same app helps you wind down and stay composed while you move. FOUR AMBIENT VISUALS Breathing Orb, drifting Particles, Fire, and Horizon Breath. Color and motion shift with your coherence — a living visual, not a chart. NUMBERS STAY OUT OF YOUR WAY The clock is hidden during a session and your data graph waits for the post-session summary. Coherence first, by design. PRIVATE BY DESIGN Cohera runs on the Apple Watch you already own and works with your own heart-rate data. No account required to start. HONEST ABOUT WHAT IT IS The Coherence Index is Cohera's own measure of how well your heart followed your target rhythm — it's a training signal, not a medical or diagnostic tool. Cohera is for everyday calm and focus; it doesn't treat, diagnose, or prevent any condition. Built by an independent developer who wanted a calm session you can do with your eyes closed — and proof it actually worked.

Wake up inside your dreams. DreamKnock turns your Apple Watch into a lucid-dreaming trainer. While you sleep, the DreamSense™ engine reads your heart-rate dynamics and wrist stillness to sense when you're dreaming — then plays a gentle, distinctive haptic rhythm, soft enough not to wake you. Trained by day, that rhythm means exactly one thing inside a dream: this is a dream. HOW IT WORKS • Tap Start Sleep, set your intention, and drift off • DreamSense™ fuses heart-rate dynamics, micro-motion atonia sensing and sleep-architecture modeling — self-calibrating to your body every single night • When REM holds, a quiet cue slips into your dream BUILT TO PROTECT YOUR SLEEP • Adaptive backoff: if a cue wakes you, the next one waits twice as long; three awakenings stop cues for the night • Cues wait for the REM-rich second half of the night • A battery guard ends the session gracefully and saves your report THE COMPLETE METHOD • Wake Back to Bed (WBTB) timed gentle wake • MILD intention screen at bedtime • Daytime rhythm training and reality-check reminders • Morning report: REM timeline, cue moments, heart-rate curve, sleep latency • Dream journal with dictation, lucid wins and dream-sign tags • Trends: lucid rate, REM per night, your top dream signs • Three cue rhythms, three strengths PRIVATE BY DESIGN No account. No cloud. No analytics. Heart-rate data is processed on your watch via HealthKit and never leaves the device. Your Apple Watch runs the whole night on its own — your iPhone can charge in another room. Requires iPhone (iOS 17) and Apple Watch (watchOS 10) or later. DreamKnock is a wellness tool, not a medical device. Sleep inferences are estimates and vary by person.
