Haptic reality checks
Throughout the day, a vibration so subtle only you feel it nudges you to ask: am I dreaming? That habit follows you into REM — and that's where lucidity begins.
Introducing LucidRing
A smart ring that reads your REM cycles and gently trains your mind — with whisper-soft haptic reality checks — to become aware while you sleep.
You spend a third of your life asleep. LucidRing turns that time into the most vivid, intentional space you'll ever explore — by catching the exact moment your mind slips into REM.
01 — Sensing
The ring reads your heart rate through the night, about every ten minutes. From that one signal the app estimates your sleep stages, and predicts when REM is due from your own recent bed and wake times.
02 — The system
Throughout the day, a vibration so subtle only you feel it nudges you to ask: am I dreaming? That habit follows you into REM — and that's where lucidity begins.
Inside a REM window predicted from your own recent nights, the ring buzzes — and holds the cue back while your heart rate still reads deep. Up to four a night, at least twenty-five minutes apart.
Wake into a guided voice-to-text journal timed to your last REM window, so the dream is still warm. Patterns surface. Recall compounds.
Nights sync both ways — Apple Health on iPhone, Health Connect on Android. If a watch already measured your stages, those win. The ring's estimate never overwrites a measurement, and every night tells you which it was.
The signal you trained yourself to notice arrives — and the dream becomes yours to shape.
03 — The coach
Speak the dream before it goes. The Dream Coach writes it down as you talk, finds the dream signs you keep returning to, and draws what you describe. It remembers the characters who come back.
04 — The dialogue
Sonar maps an ocean it cannot see. Physicists read hidden quantum systems from the echo of a single disturbed qubit. Your mind does the same thing every night — the echo is called a dream.
All day, a whisper at your finger asks one question: am I dreaming? Asked often enough, the question sinks beneath the surface — and travels with you into sleep.
Inside REM, LucidRing delivers its cue — a disturbance so small only the dream can feel it. The dream bends around it, and begins to notice itself.
What returns is lucidity — and, by morning, a journaled dream: a map of territory you've been walking your whole life in the dark.
Every dream is an answer to a question you didn't know you were asking. LucidRing teaches you to ask on purpose.
05 — The object
Titanium, a champagne-gold inner band, and a finish quiet enough that you stop noticing you're wearing it.

Sometimes. The cue is timed into a predicted REM window and held back while your heart rate still reads deep — but the ring's motor has one fixed pulse, not a calibrated one. If it wakes you, switch the overnight cue off in Settings, or take the cue on an Apple Watch, where you choose the pattern.
You don't — but consistency is everything. Lucid automates the reality-check habit and times its cue to the one moment it matters most, which is what most people can't do on their own.
The echo experiments are real physics — researchers map hidden quantum systems by disturbing a single qubit and reading what returns. We borrow that as an analogy for what a small, perfectly timed cue can reveal about a hidden system. The ring itself is straightforward engineering: optical heart-rate and motion sensing — nothing quantum. The techniques it automates (reality checks, REM-timed cues, morning recall) come from published lucid-dreaming research.
LucidRing estimates your sleep stages — it reads heart rate, not brain activity, and it is not a medical device. When a watch writes measured stages into Apple Health or Health Connect, those take precedence over the ring's estimate, and the app tells you which you're looking at. We have not run a polysomnography comparison, so we don't quote an accuracy number.
Yes. The Android app matches iPhone on the parts that matter: pairing, cues, the sleep pipeline, journal, coach and training. Two things are iPhone-only today — speaking a dream to the coach, and the Apple Watch companion, which is where you can shape the haptic pattern.
Both, from Account & Settings, on either phone. Export writes your dream journal to a file you can keep. Delete erases your dreams, nights, coach conversations and dream images from our servers, then the account itself — in that order, so a failure leaves you able to sign in and try again.
Tracking, journaling, training and the Dream Coach are free. LucidRing Plus — $6.99 a month or $49.99 a year — raises your AI dream images from five a month to forty. It's an in-app purchase, and it isn't on sale yet.
We haven't set a ship date. The first end-to-end test on physical hardware hasn't happened yet, and we won't publish a date before it does. Your deposit is fully refundable at any point until we do.
