Sleep Is the Habit Your Audience Already Has

Nutrition, movement, mindfulness, recovery: every wellness goal runs through sleep. It is the one behavior your audience repeats every single night, which makes it one of the most powerful ways to keep people engaged with your brand.

Sleep Cycle helps you tap into that habit, whether you want to build sleep intelligence into your own product or bring a ready-made sleep experience to your audience.

Why Wellness Brands Build on Sleep Cycle

Drive Engagement and Retention

Sleep happens every night. That makes it one of the stickiest touchpoints you can own: a daily reason for people to come back, whether that habit lives inside your product or in an experience you provide.

Reach Everyone, No Wearable Required

Sleep tracking works with the standard microphone already in your audience’s phones. Reach everyone, not just the segment that owns a ring or a watch.

Add Value Fast

Skip years of R&D. Embed ready-to-use sleep features, or bring your audience a complete sleep experience, and strengthen your offering in a fraction of the time it takes to build from scratch.

Build on Trusted Science

Sleep staging validated against polysomnography and developed with leading universities. Give your audience insights they can believe, and your brand a credibility advantage.

Ways to Partner

Whatever role sleep plays in your product and your business, there is a way to bring it in. We shape the partnership around your needs.

Build With Our SDK

Embed accurate, contactless sleep tracking directly into your own app. You own the experience and the interface; we provide the validated sleep intelligence behind it. Best for brands that want sleep to live natively inside their product.
