Sleep.ai Debuts Sleep Sense to Transform Smartphones into Scalable Sleep-Tracking Tools

Sleep.ai has introduced Sleep Sense, a new platform designed to convert any smartphone into a frictionless, privacy-conscious sleep sensor capable of delivering nightly measurement for nearly all users. The solution removes the need for wearables, additional hardware or daily user interaction, aiming to broaden access to consistent sleep data across diverse populations. Sleep Sense builds on Sleep.ai’s established position in sleep analytics, which has been supported by nearly one billion hours of proprietary data and more than 250 scientific studies.

Sleep Sense is designed to address a widespread measurement gap in sleep health. Despite sleep being a central indicator of long-term wellbeing, only a minority of adults actively track it through wearable devices or apps. This has limited the availability of actionable insights for individuals and reduced the ability of organizations to personalize interventions or validate program outcomes. Sleep Sense automates the entire process, enabling sleep detection through the smartphone alone and requiring no behavioural changes from the user.

The technology uses AI-driven, multimodal inference techniques to identify sleep and wake periods while maintaining strict privacy protections. The system operates without audio recording or sensitive data capture and relies on signals such as movement, light exposure and device interaction patterns. According to the company, hybrid spatio-temporal boundary detection allows accurate identification of bedtime and wake time, reaching confidence levels comparable to trackers assessed against polysomnography. All components have been built to meet GDPR and ISO requirements, ensuring that no information from within the user’s bedroom is stored or transmitted.

Colin Lawlor, Founder and CEO of Sleep.ai, said: “Sleep Sense is a major step forward for the entire health and wellness ecosystem. Sleep has always been one of the most powerful determinants of overall health, but until now it has never been measured at scale because of the reliance on wearables or daily user effort. With Sleep Sense, every smartphone becomes a sleep-sensing device. Organizations can finally personalize programs, understand risk, and measure outcomes across nearly their entire population.”

The launch follows heightened global interest in scalable sleep-health solutions, accelerated by Sleep.ai’s earlier introduction of Dein Schlaf, a reimbursed sleep-improvement app in Germany. By eliminating friction and expanding measurement reach, Sleep Sense offers new opportunities for digital health platforms, insurers, wellness providers and AI developers. Organizations can derive population-level insights, enhance predictive models with broad and unbiased datasets and develop new services without investment in dedicated hardware.
