Insights at Scale Improve Health Drive Growth
Movement
Sound-based detection picks up tossing, turning, and micro-awakenings without asking you to wear anything on your wrist or body all night.
Coughing
The SDK naturally identifies and timestamps coughing episodes that can signal irritation, illness, or poor air quality.
Breathing
It provides breathing-related insights without the discomfort of chest straps or dedicated respiratory devices.
Snoring
Detect and quantify snoring patterns on both sides of the bed, revealing how often and how intensely each partner snores.
Noises
Environmental noises such as traffic, pets, or household sounds are automatically logged and aligned with your sleep timeline.

Sleep Science at Scale
Every night, more than a million people trust Sleep Cycle to understand and improve their rest. Across 15 years and 75 million downloads, that trust has built something extraordinary: the world’s largest sleep intelligence database, with over 3 billion nights of analyzed data. But data alone doesn’t create insights. Our scientists turn numbers into knowledge, transforming society at scale through scientific partnerships with leading universities. When you work with Sleep Cycle, you gain access to the most comprehensive sleep data resource on Earth. Science with purpose, applied at scale.
Flexible integration. Deploy audio identification as standalone data. Add sleep analytics.
Or use complete feature modules. Match the SDK to your needs.
SLEEP SCIENCE
Lab-Grade Sleep Tracking, Anywhere.
Sleep Cycle's audio-based technology transforms any smartphone into a precision sleep lab. Using only the device's built-in microphone, our SDK measures sleep duration, latency, timing, efficiency, sleep stage dynamics, and variability. All with clinical-grade accuracy.
This innovation brings validated sleep tracking to scale. Individuals gain detailed nightly reports. Partners gain a seamless way to embed validated sleep insights into any digital product or ecosystem.
It is the technology that redefined what sleep tracking could be, and today, it powers the next generation of health intelligence.

UNIQUE TRAINING DATA
A Data Set of 15 Million Verified Sleep Samples
Most AI sleep models are trained on thousands of samples, and can potentially match expert-level performance for typical adult sleepers. The real challenge lies in the long tail, encompassing individuals with conditions such as apnea or insomnia, as well as users on various devices or firmware. Moving up to 15 million samples means these rare patterns appear hundreds or thousands of times rather than just dozens, giving the model enough exposure to perform consistently across all these subgroups rather than just performing well on average.
For SDK partners, this distinction translates directly into risk reduction. A model trained on a larger number of nights means fewer surprises in production, fewer support escalations about edge cases, and the ability to confidently roll out to an entire user base rather than just the easy cases.
