About

Turn “you snore” into a thoughtful next step. Lullaby Sleep helps couples collect a few nights of private evidence, review what happened together, and decide what to do next. It focuses on useful observations—not a sleep score. MONITOR ON YOUR TERMS Start a session only after everyone in the room agrees. Lullaby estimates probable snoring periods while the iPhone is placed near the bed. REVIEW THE NIGHT TOGETHER See recording coverage and a simple timeline of probable snoring periods. Add morning check-ins from the person who may snore and their bed partner to capture both perspectives. TAKE A SENSIBLE NEXT STEP After a few usable nights, Lullaby can suggest collecting clearer evidence, trying one low-risk change at a time, or discussing observations with a clinician. PRIVATE BY DESIGN • Sound classification happens on the iPhone • No account, cloud upload, advertising SDK, or tracking • No raw full-night audio is retained • Session markers, check-ins, and preferences stay in local app storage • Delete all local data whenever you choose BUILT WITH SAFETY IN MIND Lullaby Sleep includes shared-room consent reminders and clear guidance for symptoms that deserve professional attention. Lullaby Sleep is an informational wellness tool. It does not detect or diagnose sleep apnea or any other medical condition. Results can be affected by bedroom noise, another sleeper, device placement, and interruptions. Formal clinical testing is required for diagnosis. If someone is dangerously sleepy, avoid driving or safety-critical work and seek medical advice.
