Private sleep intelligence for iPhone

Your night,
handled automatically.

DreamOS learns your rhythm from Apple Health data you choose to share, explains whether recovery was likely restorative, and quietly prepares the next night.

Less tracking.
More useful mornings.

DreamOS turns permitted signals into a clear wellness estimate, with confidence and limitations always visible.

Learns your normal

Adaptive machine learning builds a personal baseline from your recent sleep duration, rhythm, and available recovery signals.

Explains the night

Duration, continuity, regularity, heart-rate patterns, breathing stability, and available environment context are separated clearly.

Prepares what’s next

Wind-down reminders, morning summaries, and safe schedule boundaries run automatically while you remain in control.

A complete view, honestly framed

Signals become context—not a diagnosis.

DreamOS weights only the information available for that night and lowers confidence when data is limited.

General wellness only. DreamOS does not diagnose insomnia, sleep apnea, or any medical condition. Persistent concerns or daytime sleepiness should be discussed with a licensed clinician.

Present without being distracting

Always available.
Never demanding.

Home Screen and Lock Screen widgets show the essentials. A privacy-safe Live Activity can remain visible on supported Always‑On iPhones and in Dynamic Island.

Always‑On presentation requires a supported iPhone, enabled Live Activities, and the relevant system settings. Lock Screen content avoids raw biometrics.

Wake to clarity,
not another task.

DreamOS for iPhone is in launch preparation. The first release supports iOS 18 and later, with enhanced system alarms on compatible newer iOS versions.
