Your sleep does two things, and until now, no app told you about either of them. DreamSweep is the first sleep app that separately scores how well you recovered overnight and how well your sleep supported brain clearance.
sleep. sweep. restore.
WHY TWO SCORES?
Sleep research has shown that sleep serves at least two distinct biological functions. Restoration is how your brain resets: synapses are pruned, memories are consolidated, and cognitive capacity is replenished. Brain waste clearance is a separate process: during deep sleep, the glymphatic system flushes out toxic proteins like amyloid-beta and tau, the molecules linked to Alzheimer disease.
These two processes depend on different aspects of your sleep and can vary independently. A great night for recovery can be a poor night for brain clearance, and vice versa. Every other sleep app collapses this into one number. DreamSweep gives you both.
YOUR TWO SCORES
Restorative Sleep Score (RSS): Did your body and mind get what they needed? Modeled on sleep-lab methodology. Combines sleep duration, continuity, cycle architecture, and timing stability, scored against age-appropriate clinical norms.
Brain Clearance Opportunity (BCO): Did your sleep support brain clearance? Based on the emerging science of the glymphatic system. Tracks deep sleep quality and heart-rate variability patterns linked to brain clearance activity.
WHAT MAKES DREAMSWEEP DIFFERENT
Two scores, two biological questions, not one opaque number. Every parameter traceable to a published scientific norm. Age-fair scoring: a well-slept 65-year-old earns a high score on age-appropriate criteria. Fully transparent algorithm, no black box, every weight explained. Grounded in peer-reviewed sleep science and glymphatic research. Graceful degradation: missing sensors drop out, your score always works.
WHO IS DREAMSWEEP FOR
Health-conscious adults who have outgrown single-number sleep scores. People investing in longevity and brain health. Users who want to understand their sleep, not just track it. Whether you are 30 and optimizing performance or 60 and protecting cognitive reserve, DreamSweep gives you the answers that matter.
THE SCIENCE
DreamSweep is grounded in decades of sleep research, including the seminal discovery of the glymphatic system by Iliff and Nedergaard (2012), landmark studies on sleep-driven brain clearance (Xie 2013, Fultz 2019), and AASM clinical scoring standards. Every scoring parameter traces back to a published source.
REQUIREMENTS
Works with Apple Watch (Series 4 or later) and Apple HealthKit. Also works with other HealthKit-connected wearables (some physiological features require Apple Watch). No special permissions or entitlements required.
DreamSweep is a wellness product, not a medical device. Scores are wearable-derived estimates and are not intended to diagnose, treat, cure, or prevent any disease.
